Several research studies have made it possible for us to understand that population growth continues to increase day by day and that, if concrete environmental measures are not taken, resources will become insufficient. The same occurs with the modality of productivity and massive and indiscriminate consumption that, if it follows the upward and progressive curvature, can lead to serious consequences for the world we inhabit. That is why it is totally necessary to take the appropriate actions that lead us to develop a sustainable industry and the key is in the circular economy. Circular Economy and the Good Use Of Plastic. The Circular Economy seeks to keep products, materials and resources in the economy for as long as possible. In this way, the use of new resources and the generation of waste are minimized, favoring their reinsertion in the value chain by reusing and / or remodeling the useful life of a product. In the case of plastic, derived products are characterized by being resistant to corrosion and attacks by various chemical agents. This makes them especially useful among other things for packaging, textile articles and product, liquid and food packaging. However, one of its main drawbacks lies in the time it takes to decompose: between 100 and 1000 years, depending on the size and type of plastic. After glass, it is the second most slowly decomposing material. Plastic pollution emphasizes the importance of the plastic recycling process. The PET bottle recycling and washing line is a device that has been designed to provide a rather smooth and easier recycling process. Is It Possible To Achieve Sustainability Through Plastic Recycling? Currently, plastics are at a crossroads where all their benefits are being overshadowed by the problems caused by their abandonment in the environment and especially in our seas. Therefore, innovation in the sector is essential to face this new challenge, to develop new recycling technologies, create new business models and ultimately evolve towards a circular and therefore more sustainable economy. One of such example is the high quality plastic recycling machine. Results of An Industry Aimed At Sustainability: Sustainability must cut across the economic, social and environmental factor. The best way is to encourage those actions that have to do with the ecological transition and discourage those activities that are not related to the field of sustainable development. And although government agencies with a national and international framework intervene in regulations, citizens in their role as consumers have a relevant role in achieving the objectives of sustainable development and, of course, the business sector, which must have as its objective grow and act sustainably. The applications of the resulting products vary depending on the type of material in question (PET, HDPE, FILM). Among the most common are: PET: textile fibers, carpets, rugs, trays, packaging blisters, electrical connectors, elements for the automotive industry. HDPE: low pressure pipes for irrigation, flowerpots, drugstore bottles, broom and mop bases, buckets, containers, litter bins, etc. FILM: hoses, temporary waterproofing, pipes, industrial film, carafe protection, garbage bags, etc. A wide range of plastic recycling machine for sale in the global market further buttresses the strength of the manufacturers in responding to the issue of pollution in our environment.

Reducing plastic is a top environmental concern for governments and customers. Using paper products instead of plastic is a good choice. There are two main reasons why people use paper bags. First, plastics are recycled without releasing toxic and toxic gases into the atmosphere. Paper bags are usually 100 percent recyclable. Paper bags can be reused and pollution-free. Despite the low durability of paper bags, one advantage of paper is that it breaks down much faster than plastic and poses a risk to wildlife. Plastic bags can take 400 to 1,000 years to decompose. Finally, paper bags still need to be used one less time over their lifetime to make them more environmentally friendly than single-use plastic bags. Ningbo New Glory Machinery: professional paper bag machine, we produce paper bag production line: square bottom paper bag machine, V bottom paper bag machine, printing machine,cutters and handlebar machine. Your inquiries are welcome.

Plastic bags can be divided into side sealing bags, bottom sealing bags, middle sealing bags and three side sealing bags according to the processing technology. Production of the time of the process is also different, especially three side sealing bags, in life can be used for food, cosmetics and other packaging bags, very common. The production of three side sealing bags, every step is necessary, indispensable, interlocking, closely linked together. (1) the premise of making three side sealing bags: the use of feeding rack, through a cylinder control iron slide up and down, convenient feeding, drum with snail QQ dead. After feeding, use a low pressure wide bag to bind the film. The reel rotates counterclockwise. (2) The two step of the three-side sealing bag production is to use the tail frame cots, the two cots are pressed, driven by a small motor to rotate and traction film. (3) The material receiving rubber roller, up and down two, take turns to replace the material (4) In the middle process of making three-side sealing bags, printing steps are carried out: the upper and lower iron rollers in front of the printing machine are used for feeding and collecting materials. There is a tracking machine in front of the iron roller, until the tracking material swing error, control the printing error distance within 1MM. (5) Printing machine offset printing, it is three-dimensional, the height of 4 meters, a circle of plastic bag film is estimated to be about 40 meters -- the structure of the film is constantly folded, can print 1 ~ 4 colors. (6) Copperplate printing is in long shape, about 15 meters long, and it is estimated that 80 meters long for a circle of film. Can print 1 ~ 8 colors or 1 ~ 10 colors. (7) Rolling curtain is generally made of mat or plastic, which mainly plays a role of pressure and tension control. An inductor behind the cursor detects whether there is a film in front to control the operation and stop of the tailstock cots motor. Stop when there is, and move when there is no. (8) Pause board Made of stainless steel, it acts as a flat film to prevent bag wrinkles and ensure bag size. So the pause board should be flat. Light weight items can be placed above the film to flatten the film. (9) An important step in the three-side sealing bag: sealing

Eight side sealing bag making machine added a new function, namely "up and down printing control mode". Although we can make square bottom bag with bag height of 800mm, but the large bag printed on the inside is limited by the width of printing machine and compounding machine. "Upper and lower printing control mode", can use the upper and lower printing, compound film, without replacing the printer and compound machine, can produce large bags (large height). Can produce high 800mm large capacity square bottom bag. Can be attached with ordinary zipper and slider zipper, easy to operate. The sealing method of the side insert is "three-dimensional folding edge insert" (45 degrees folding edge insert). It can be completely sealed without rubber strip.

First, heat sealing temperature The choice of heat sealing temperature of composite film is closely related to the performance and thickness of composite substrate, the type, speed and heat sealing pressure of bag-making machine, which directly affects the level of heat sealing strength. The sealing temperature of composite film is determined by the viscous temperature Tf (or melting temperature Tm) of the heat sealing material, and the high temperature of heat sealing can not exceed the decomposition temperature Ta of the heat sealing material. The temperature range between Tf (Tm) and Ta is the heat sealing temperature range of the heat sealing material. It is the key factor affecting the quality control of heat sealing. The wider the temperature range of heat sealing, the better the performance of heat sealing, the easier and more stable the quality control. At the same time, the heat sealing temperature of the composite film can not be higher than the heat setting temperature of the printing material. Otherwise, it will cause shrinkage and wrinkling of the heat sealing part, reducing the heat sealing strength and the impact resistance of the bag. Good heat resistance of printing materials, such as PET, ONY, etc., can increase the heat sealing temperature in production to rapid production; Printing materials with poor temperature resistance, such as BOPP, try to use a lower heat sealing temperature, and by increasing pressure, reduce the speed or choose low temperature heat sealing materials to ensure the heat sealing strength. Heat sealing temperature setting should be in heat sealing temperature range of heat sealing material, generally in the viscous flow temperature Tf (or melting temperature Tm) on 15 ℃ ~ 30 ℃ (if within the scope of this, cannot make heat sealing layer sealing, must be from the pressure up to try to improve, speed, mechanical properties, the greater the pressure is not the better, too big welding edge will damage, increased problem. "Supplementary discussion"), the heat sealing material in the heat sealing part is easy to be fused out due to the high heat sealing temperature, which reduces the heat sealing thickness and increases the thickness and non-uniformity of welding edge. Although the apparent heat sealing strength is high, it will cause root breakage phenomenon, greatly reducing the impact resistance of sealing (easy to produce the problem of broken bag, "supplement"), sealing performance. (This analysis makes a lot of sense.) Heat sealing temperature is lower than the softening point of heat sealing material, increasing pressure and prolonging heat sealing time can not seal the heat sealing layer. The heat sealing temperature of continuous automatic filling equipment is often set at a higher temperature, because during heat sealing, it is easy to be affected by the pollution of the contents, extrusion and cooling speed. Two, heat seal pressure At the heat sealing temperature, the heat sealing material begins to melt, and pressure is applied on the bonding surface to make the corresponding heat sealing material contact with each other, penetrate and diffuse, and also promote the gas on the surface of the film to escape, so that the distance between molecules on the surface of the heat sealing material is reduced, resulting in greater intermolecular force, thus improving the heat sealing strength. (Add heat seal theory) The heat sealing pressure is provided by a spring on the bag-making machine. For lightweight packaging bags, the heat sealing pressure is at least 1. Larger than 96N/ cm ². The size of heat sealing pressure is related to the structure, thickness and heat sealing width of the composite film. The heat sealing material has high activation energy, and the temperature rise has a great influence on the decrease of its viscosity. The heat sealing pressure required is small, so as to avoid the molten material in the heat sealing part being extruded and reduce the heat sealing effect. PE and PP are non-polar heat sealing materials with very small activation energy and high pressure, which are favorable for heat sealing strength and interface heat sealing property. (how to understand this time, should be heat sealing materials of heat sealing material has high activation energy and low activation energy of heat sealing materials, PE, PP is a common heat sealing materials, referred to in here should be a common type of PE, PP material, belongs to the activation energy of smaller heat sealing materials, with copolymerization, blending modification, or special heat sealing materials, such as catalytic, ionic resin Such as mPE, EVA, EAA, EMAA, Surlyn, etc., are heat sealing materials with high activation energy pickaxe. I wonder if this understanding is correct. The heat sealing pressure increases with the increase of the thickness of the composite film. If the heat sealing pressure is insufficient, it is difficult to heat seal the propylene film and exhaust the bubbles sandwiched in the middle of the weld. The heat sealing pressure is too high, will squeeze out the molten material, damage the welding edge, cause root breakage. When calculating the heat sealing pressure, consider the required width of the heat sealing rod (the width of the heat sealing rod rather than the entire width of the rod) and the actual surface area (the area of the heat sealing contact). The wider the heat sealing rod width, the greater the pressure required. The width of the heat sealing rod is too wide, easy to entrap bubbles in the heat sealing part, it is difficult to heat sealing firmly. Hollow heat sealing rod is generally used to strengthen the heat sealing fastness. For heat sealing rod with the same width (heat sealing width), if the surface is engraved, the actual contact area is greatly reduced and the pressure per unit area is correspondingly higher. This is beneficial to heat seal wide packaging bags. Three, heat sealing speed Heat sealing speed reflects the production efficiency of bag making machine, and is also an important factor affecting heat sealing strength and appearance. The higher the heat sealing speed, the higher the heat sealing temperature to ensure the heat sealing strength and state; Under the same heat sealing temperature and pressure, the slower the heat sealing velocity is, the fusion of the heat sealing material will be more sufficient and stronger, but the phenomenon of root breakage can not be caused. In domestic bag making machine, the length of heat sealing time is mainly determined by the speed of bag making machine. Increase the heat sealing time, must reduce the bag-making speed, reduce the hand production efficiency. If an independent variable frequency motor is used to control the lifting and feeding of the heat sealing rod, and adjust the heat sealing time independently without changing the bag-making speed, the operation and quality control of the bag-making machine will be greatly convenient. (Several domestic manufacturers can produce this kind of bag-making machine, using three frequency conversion motors, one independent control of heat sealing time. At present, the smic 600 bag making machine purchased belongs to this kind, not the above mentioned domestic bag making machine controlled heat sealing time production is determined by speed.) Four, cooling conditions Cooling process is under a certain pressure, with a lower temperature to just melt sealing weld shape, eliminate stress concentration, reduce the contraction of the weld, improve the appearance of the bag flatness, improve the heat sealing strength of the process. The cooling water of bag-making machine is generally tap water or circulating water of about 20℃. If the water temperature is too high, the pressure of the cooling rod is not enough, the circulation of cooling water is not smooth, and the circulation amount is not enough, it will lead to poor cooling, and the heat sealing strength will be affected. Five, the number of heat sealing In continuous automatic filling equipment and some bag-making machines, longitudinal heat sealing generally adopts the ring steel belt welding method coated with POLYtetrafluoroethylene, and transverse heat sealing adopts hot plate welding method. However, most of the longitudinal and transverse heat sealing of bag making machine adopts hot plate welding method. The number of longitudinal heat sealing depends on the effective length of heat sealing rod and the ratio of bag length, and the number of transverse heat sealing is determined by the number of heat sealing device group of the machine. Good heat sealing generally requires heat sealing in more than two times. Transverse heat sealing devices are mostly composed of three groups. In order to meet the requirements of wide edge heat sealing, transverse heat sealing devices are often added to increase the number of heat sealing to reduce the heat sealing temperature and reduce the necking phenomenon. For longer specifications of the packaging bag, can use multiple feeding technology, so that each feeding length is reduced to half or one-third of the bag length, so as to increase the number of heat sealing, improve the heat sealing effect, but will reduce the production efficiency, so some bag making machine to increase the length of longitudinal sealing rod, to increase the number of heat sealing, to ensure the quality of heat sealing. Six, heat sealing bar clearance The heat sealing bar gap refers to the applied distance of the predetermined heat sealing pressure to the heat sealing surface when the upper heat sealing bar contacts the bottom plate. When the film thickness is the same and the heat sealing speed is the same, the heat sealing rod gap is small and the heat sealing time is relatively small, and the heat sealing strength of the product will be reduced. Generally, the gap of heat sealing rod is set at 1 ~ 1.5mm, which is related to film thickness, transfer performance and bag-making speed. (If an independent variable frequency motor is used to control the lifting and feeding of the hot sealing rod and adjust the heat sealing time independently, the bag-making speed should not matter.) Seven, Tension control Tension control device is used to keep the film smooth, easy to fold, intermittent feeding uniform, reduce the shrinkage and warping of the bag heat sealing part. The tension of bag-making machine is generally in 1 ~ 1.5㎏/㎝². (The effect of tension control and the difference between good and bad is to be added after discussion with the normal flow.) Conclusion 1, the heat sealing quality of composite soft packaging bags is mainly evaluated by appearance inspection, heat sealing strength, compressive strength, impact strength, etc. In professional standards, the provisions of heat seal strength and pressure time are lacking. (The deficiency is in what place, need to contact or check information supplement.) 2, heat sealing temperature, heat sealing pressure, heat sealing speed, cooling system, heat sealing times, heat sealing bar clearance, tension control and other technological factors are important factors affecting the strength and appearance of heat sealing. 3, the quality of heat sealing depends on the selection of heat sealing materials and the determination of production process, but also pay attention to other factors affecting the heat sealing strength: the structure and material of composite film, the composite strength between layers, printing typesetting, layout design (ink area), heat resistance of ink and adhesive, etc..

Film feeding time and heat sealing time of New Glory bag making machine can be set separately. On this basis, derived only ding MAO machine bag making machine functional heat sealing waiting time ". This function mainly plays an important role in the necessary adjustment operation when the bag-making machine starts or replaces the roll film. The bag-making machines of other companies, when adjusting brick transport, slow down the film feeding time in order to control the waste of film, and then adjust the operation while fine-tuning the position of heater and incision. At this time, the heater's heat sealing time, which is proportional to the film feed time, also becomes longer. In order to reduce the load of the heater, it is necessary to lower the temperature of the heater in advance. Then, a series of fine tuning work, such as shortening the feed time of the film, confirming the heat sealing strength and the appearance of the finished bag while gradually increasing the temperature of the heater, should be done before the fine tuning is about to end and enter the formal operation. In the past, this adjustment mode not only wastes time, but also wastes more film in the adjustment process. As for the heat sealing waiting time function of New Glory Machinery, in the adjustment operation stage, as long as the heat sealing time is set at 0.5 seconds, the temperature of the heater is adjusted to 200 degrees as the set value, and the feed time of the film is set at 0.25 seconds < the same as the set value in the formal operation >. In this way, the "gap" time between the heater rising after a heat seal and the next heater falling is the heat seal waiting time. This time can be set separately, assuming 1.25 seconds, it is very easy to adjust the heater or cutting position. And after the fine tuning, as long as the heat sealing waiting time is set to 0 seconds, it can be simply transferred to the formal operation. Through this film feed time (film transfer speed) and heat sealing time (control part of the heater up and down action) respectively set the function, in the adjustment stage can greatly reduce the film waste, so as to improve the production efficiency. Heat sealing waiting time function is another important reason for ding MAO machine bag making machine to be selected by the majority of customers.

The plastic we usually use in the zipper bag making machine is not pure material, they are made from many materials. In addition, in order to improve the performance of plastic zipper bag making machine, filler, stabilizer and colorant should be added to the polymer to make it an excellent plastic. Synthetic resin is the main component of plastic, due to its high content, and the nature of the resin often determines the nature of plastic, for example, PVC resin and PVC plastic confusion, phenolic resin and phenolic plastic confusion. Actually, it's two different things. Zipper bag making machine Resin is a kind of high polymer raw material, it is not only used to manufacture plastics, but also is the raw material of coatings, adhesives and synthetic fibers. In addition to most plastic, there is a small amount of resin. Fillers, also known as fillers, can improve the strength and heat resistance of plastics and reduce costs. Adding wood flour, for example, can greatly reduce the cost of phenolic resin, making it one of the cheaper plastics, and significantly improve its mechanical strength. Computer bag making machine Zipper bag making machine packing the former such as wood powder, and a variety of fabric fiber, the latter such as glass fiber, asbestos, carbon black, etc.. Plasticizers increase the brittleness of plastics and make them easier to work with. Plasticizers are usually organic compounds with high boiling points, miscible with resins, non-toxic and tasteless, light and heat stable, among which phthalate esters are commonly used. Hot seal hot bag making machine For example, zipper bag making machine in the production of PVC plastic, if more plasticizer is added, you can get soft PVC plastic; In the case of no addition or reduction of plasticizer (dosage < 10%), hard PVC plastics can be obtained. In order to prevent decomposition and damage of synthetic resin during processing and prolong service life, stabilizer should be added. Zipper bag making machine commonly used stearate, colorant colorant. Organic dyes and inorganic pigments are commonly used as colorants to prevent plastic from sticking to metal molds during the molding process, so that the plastic surface is smooth and beautiful. Common lubricants are stearic acid and its calcium and magnesium salts. In addition to the additives mentioned above, flame retardants, foaming agents and antistatic agents can also be added to plastics to meet different requirements. Zipper bag making machine performance characteristics: integrated the advantages of similar models at home and abroad, compact and reasonable mechanical structure, low operating noise, color bag white bag conversion, photoelectric detection, colorless time mark, mechanical automatic high stop alarm. This machine is highly automated. It is an ideal bag making machine for sealing and clamping plastic bottom.

We have been widely used to pack shirts, socks skirts, pants, socks, towels, bread and stocking bags. Usually the bag has a sticker on it and can be directly sealed after being put into the product. This kind of bag is very popular and widely used in the domestic market. Because of its good transparency, it is also an ideal choice for wrapping gifts. This kind of bag in the clothing processing factory, cloth wholesale market, small commodity wholesale market, food industry demand and large, only in the summer generally a small clothing factory demand should reach at least 1.5 million. If there is a pattern printed on this bag, its transparency and clarity of pattern are uncomparable to other plastic bags, which is a powerful publicity for the enterprise in promoting the brand.

Today we face the greatest environmental challenges in history which is that the production of plastic is far more than the amount of plastic that is recycled. The consequences of the manufacture of plastic for years have become an environmental problem because production increases faster than recycling. To solve this problem it is important to know how to recycle plastic effectively. Plastic recycling today For some years now, the consequences of throwing plastic directly on land or in the sea have become significant. And the truth is that the plastic always comes back to us since the plastic particles take up to 500 years to degrade completely. But the problem is not only plastic, but microplastics. These small plastic particles come from objects that have been wearing down into little plastic granites. Microplastics and plastic recycling Nowadays, a large number of microplastics can be found on beaches that are confused with sand. It is easy for these little plastics to reach the human body by ingesting them through your favorite food, be it meat or fish. This is the real problem of having flooded the plastic plant, now it is poisoned. How to recycle plastic efficiently? In order to reverse the situation, it is important that there is an efficient system for recycling plastic, whether it be bottles, plastic bags or any other container. Recycled plastic The fact still remains that the world production of plastic increases much faster than the amount recycled, therefore there is more and more plastic waste. In few countries in the world there is an efficient policy to recycle plastic. Let`s look at some of the methods that countries with more sustainable systems have succeeded with their plastic bottle recycling machine. 1. The deposit and return system According to the Univision Norway article, it recycles 97% of its plastic and this is achieved, in addition to raising awareness among its population, using the deposit and return system. Here, when customers buy a product in a plastic container, they must pay extra money, and when they return the container, that money is returned. In this way, the consumer must not only be aware of the planet but also of their money, and this is how Norway has managed to meet the European Union's objective of recycling 90% of plastic by 2030, only they have achieved it. 10 years earlier. Here you can see a video of how the deposit and return system works to recycle plastic bottles. 2. Plastic recycling at home There are also other ways to recycle plastic without taking it to a container. You can make crafts with the plastic scraps. In green ecology they give us some tips for this type of recycling such as: Some ideas to recycle plastic bottles. Ecological bricks can be made from plastic bottles. There are also tips for recycling bottle caps. Plastic recycling process The plastic bottle recycling machine is an indispensable tool in this regard. It is a highly efficient machine that bridges the gap between the use of plastic bottles and the protection of our environment. However, there are other solutions for recycling plastics. It is necessary to take individual measures since it is everyone's problem. Some individual actions that can be taken have to do with the 3R rule: Reduce the amount of plastic packaging. You can buy food in bulk that does not go in plastic containers for example. Reuse plastic packaging or go shopping with reusable bags, thus drastically reducing the use of plastic Recycling is of course the last step, if you have already completed the other steps and the time comes when you have to dispose of some type of plastic, it is time to deposit it in the yellow container. No matter where you are, try to recycle the plastic by depositing it in the appropriate container.
