The products of plastic packaging bag manufacturers

The products of plastic packaging bag manufacturers have a wide range of use, and now there are more and more new products, but there are also some problems that need to be paid attention to. For example, plastic packaging bags themselves will release toxic gases, because the main processing components of plastic bags are polyethylene, polystyrene, etc., which will release toluene when burned, and the toxicity of this gas to the human body is still relatively obvious.

 It can also cause harm to the environment.  Zip Lock Packaging Bag Manufacturers Therefore, in the process of actual processing, it is necessary to clarify this hazard, and it must be marked during production. Do not use plastic bags to package cooked food, because this will easily lead to the deterioration of food, which will cause serious damage after entering the human body. harm.

If a garbage bag is thrown into the ground, it will never decompose, which will cause pollution to the land. So it must be used wisely.

  Plastic packaging bags are used for food, shopping, takeaway, industrial products and more. Because it is easy to process, it can be designed into different forms to meet the needs of customers. The packaging bag is not as easy to be broken as other glass forms. What are the specific advantages that make the packaging bag so widely and permanently used in life? 

1. Due to the characteristics of the material itself, plastic packaging bags can be processed into various shapes to meet the shape requirements of the packaging (functional or the appearance requirements of packaging design), and can also be used in novel shape packaging to attract the masses. Consumers' attention and arouse their desire to buy.

 2. The biggest advantage of plastic bag packaging compared with other packaging forms is that its cost is low (including materials and filling equipment), and there is a large price advantage, and the price plays a leading role to a large extent. Under the circumstance that there is not much difference in product content, product quality, product flavor and nutritional value, the vast majority of consumers still choose plastic bags. 3. Plastic bags have good mechanical strength, are not easy to break, and can withstand extrusion.

Why do vacuum bags wrinkle?

Vacuum packaging bag refers to a packaging method in which the product is added to an airtight packaging container, the air inside the container is removed, and the sealed container reaches a predetermined vacuum degree. So why are the vacuum bags wrinkled? 

1. The unwinding of the substrate is skewed. 

2. The thickness of the substrate is not uniform, and the film is too different.

 3. Insufficient drying of the adhesive, too much residual solvent, small bonding force, and displacement of the two substrates after compounding.

 4. When the amount of glue applied is too much or insufficient, interlayer sliding will occur; uneven glue application will also cause local wrinkles. 

5. Composite film The composite film is wound directly without cooling or insufficient cooling, and the soft composite film at high temperature is easy to wrinkle.

 6. The guide rollers are not parallel.

 7. The surface of each guide roller is not clean, there are foreign objects stuck, or the surface of the guide roller is uneven, with pits, scribes, bumps, etc. 

8. The tension compound pressure is not set properly. 9. Improper tension control, uncoordinated and unmatched tension of unwinding and rewinding. Vacuum packaging bags are used in vacuum packaging  Side Seal Pet Food Packaging Bag  in plastic bags, aluminum foil packaging, glassware packaging, etc.

Quality identification of plastic inner film bags

The use of plastic inner film bags has brought people a lot of assistance, but when we are using it, we still need to pay attention to distinguishing its quality. Then how should we distinguish it? Let's let the plastic packaging factory. Let’s take a closer look! First of all, what we need to know is that in daily time, if the product we use has an irritating and disgusting plastic inner film bag on it, then this clarifies This kind of product is toxic. Another possibility is that plasticizers or other additives used in it are formed by excessive use of plasticizers or other additives during the production process. 

Then the quality of this kind of product is relatively poor. There is also a need to listen to its sound. When the plastic bag is vibrated with hand, the sound is loud and loud is the non-toxic plastic bag, and the sound is dull or there is no sound, it is the toxic packaging. The last method that the plastic packaging factory introduced to us is to put the plastic bag in the water and press it to the bottom by hand. After a while,  custom stand up pouch packaging the non-toxic plastic inner film bag that comes out of the water is sinking to the bottom of the water. Is a toxic product, hope the above content will help you.

       Plastic packaging factories should pay special attention to the uniformity of the mixing if they use new and old materials to mix them during the manufacturing process. In the sewing process, there are also strict requirements on the strength. In the national standard, the tensile load in the seam direction and the seam bottom direction of the plastic packaging bag is clarified. Regarding the laminated cold-cut bag, it is recommended that the plastic packaging bag should be treated with curling, because the seam of the cold-cut edge may come from the warp.

 Tear out together with the weft. Regarding the woven bag with no strength requirement, the top stitching is one round, the needle pitch can be dense, and the thread can be thin. In addition, with regard to the tensile strength of the main body of the plastic packaging bag, it is required to reach more than 67% of the fundamental strength, and the tensile strength of the bottom joint must reach more than 42% of the fundamental strength. In fact, the main factors that affect the stitching strength of plastic packaging bags include the variety and model of the stitching thread, the size of the stitch length, the stitches, the size of the seam or hemming seam to the edge of the bag, the hot and cold cutting methods, etc.
