The double-sided adhesive sealed product is typically a plastic packaging bag, also known as a sticker bag or window bag, made of PP material. The bags are very transparent and smooth to the touch, but they are also very rigid and脆, making a loud sound when folded. Folding them creates creases, so sticker bags are not folded. They can be粘贴d to cardboard boxes to hold various documents, such as PE bags, which are also transparent but not as clear as OPP. Therefore, PP bags have a price advantage over OPP bags. PP material is more expensive than PE material.

Adhesive-backed bags not only have a great development in logistics but are also commonly used in everyday life to store essential documents, such as notebooks and bankbooks, etc. Therefore, adhesive-backed bags are always present in our lives.
