What is a self-adhesive bag

Self adhesive bags can be said to be a daily necessity, and many things in production require self-adhesive bags. The self-adhesive bags produced have been used in various industries. Has received unanimous praise. Self adhesive bags are widely used in stationery, books, toys, paper products, office supplies packaging, and other industries.
Self adhesive bag: There is a piece of glue at the mouth of the bag, which is wrapped in small plastic paper when buying. When it is necessary to seal, you can tear off the plastic sheet and expose the glue to seal the bag. It is usually a disposable packaging product.
Self sealing bag: There are stitches on the opening of the bag. Align the lines on both sides of the bag, press tightly, and then close. You can tear the bag open and reuse it without glue.

Self adhesive bags are mainly produced by single film cross cutting, with both sides heat sealed. The length of the bag is different from the other side, with one side 3-5 centimeters longer than the other, and can be folded back. The folded back portion is covered with adhesive, destructive adhesive, and other colloids. When using, tear off the plastic cover on the gel and fold it back to seal.
Self adhesive bag PE material: The material body is relatively soft, but the transparency is not high enough for other materials, so it is relatively turbid and has good tension! Not explosive!
Material: The material body is hard, but the transparency is high and clear, and the tensile force is not very good! Blow your mouth!
Self adhesive bag PO: The material body is relatively brittle, not transparent enough, darker in color than PE material, a bit white, and not very tensile.
OPP material: brittle material, high transparency, insufficient tension, but easy to explode, printing easy to decolor.
Self adhesive bag PVC material: The material body is moderately soft and hard, and can be customized according to customer needs. The transparency can also meet the needs, because there are ultra-transparent materials, ordinary materials, frosted materials, good tensile strength, not easy to tear, and not allowed to explode, because the two layers of materials are spliced together by machines.
