The self-adhesive bag produced by the plastic bag manufacturer means that there is an easy-to-tear plastic strip at the mouth of the bag. When it is bought, it is covered with a small piece of plastic paper. When it needs to be sealed, the glue can be exposed by tearing off the plastic sheet. For sealing, it is generally a one-time packaging product. Self-adhesive bags can be said to be necessities of life. We need to use self-adhesive bags for many things in production. The self-adhesive bags produced by plastic bag manufacturers have been used in all walks of life and have received unanimous praise.　　The self-adhesive plastic bags produced by plastic bag manufacturers are widely used in the packaging of stationery, books, toys, paper products, office supplies, etc., because self-adhesive bags can pack goods without the help of machines. Self-adhesive bags are also called sticky bags, self-adhesive bags, ziplock bags, etc. Like other plastic bags, there are far more than one material for making self-adhesive bags. For example, PE, P0, PP, OPP, and PVC can all be used to make self-adhesive bags. If you ask which is more commonly used, then it should be PE And OPP these two materials. Plastic bag manufacturers use self-adhesive bags made of PE materials. The material body is relatively soft, has excellent low temperature resistance (low temperature can reach -100-70℃), good chemical stability, and resistance to most Acid-base corrosion (not resistant to acids with oxidizing properties). However, self-adhesive bags made of PE materials are not sufficiently transparent and fuzzy, but have good tensile strength and are not explosive. The self-adhesive bag made of PP material by the plastic bag manufacturer: The material body is relatively hard, the appearance is transparent and light, and it is flammable. The corrosion of this kind of solvent can decompose under high temperature and oxidation, but the tensile force is not very good, and it is easy to explode. The self-adhesive bag made by the plastic bag manufacturer using PO material: relatively brittle, harder, low expansion rate, crispy sound when rubbed, and slightly lower transparency than other self-adhesive bags, more masked than PE material, and a bit transparent The white color is not very good, but it has strong durability and is suitable for loading small commodities.　　The self-adhesive bag made by OPP material by the plastic bag manufacturer: It has the advantages of high tensile strength, light weight, harmless and odorless, environmental protection, and a wide range of use. Plastic bag manufacturers use OPP material to be super transparent, smooth and flat, and can be processed into bags along the line, self-adhesive bags, card-head bags, (paper card OPP self-adhesive bags, pearl film OPP self-adhesive plastic bags), composite bags, composite self-supporting bags , Composite bone bag, composite three-side sealing flat bag, composite middle sealing bag. Plastic bag manufacturers use self-adhesive bags made of PVC materials: The material body can be soft or hard, and can be ordered according to customer requirements. The transparency can also be determined according to requirements. The PVC materials used by the plastic bag manufacturers include super transparent materials and ordinary materials. And frosted material, it has good tensile force and is not easy to tear, because the two layers of material are machined together. The above explanation is the difference between the materials used by the plastic bag manufacturer to produce the self-adhesive bag. I hope it will be helpful to you after reading it.
