What are the characteristics and uses of PE self adhesive bags and self sealing bags?
1. Characteristics of ziplock bags
It is made of polyethylene and high-pressure linear polyethylene through blown film molding, and a ziplock bag is made by a hot cutting machine. The biggest feature of ziplock bags is that they can be reused and are easy to use. The materials of common ziplock bags mainly include PE, EVA, PO, multi-layer composite zipper bags, etc. There is a sealing line at the mouth of the self-sealing bag. Align the openings on both sides of the mouth of the bag and squeeze it to seal it; the bag can be opened by tearing it open without using glue to fix the mouth of the bag. It can also be seen from this point that the ziplock bag is convenient and quick to use.
2. Features of PE self-adhesive bags
It has glue on the mouth of the pocket. The user needs to tear off the plastic sheet covering the glue to expose the glue to achieve the sealing effect. Therefore, most of the self-adhesive bags are disposable products, because the glue has limited viscosity, and the second use is not sticky enough to achieve the sealing effect.
What are the characteristics and uses of PE self adhesive bags and self sealing bags?
Since the properties and characteristics of the two plastic bags are quite different, there is also a big difference in the way of use. the
