Plastic Zip Bags

Plastic Zip Bags are made of polyethylene (LDPE) and high-pressure linear polyethylene (LLDPE) by blown film forming and hot-cutting mechanism bags to make a plastic bag that can be repeatedly sealed. Common materials are PE, EVA, PO, multi-layer composite zipper bags.

Self-sealing bags can be used to produce anti-static ziplock bags by adding anti-static masterbatch during blown film production, which is generally used in the electronics industry.
Production Process
The production of zippered ziplock bags is divided into two types, one is direct blown film forming, the above is generally 1.8CM from the self-sealing mouth, the thickness is relatively thick near the self-sealing mouth, and the left and right sides of the zipper bag are made by hot-sealing to make the finished product; the other is the latter. A method of attaching a chain, the latter method is mainly used for the production of a composite bag.
The production of self-adhesive ziplock bag is mainly made by cross-cutting of single film, heat sealing on both sides, the length of the bag is different, the side is 3-5cm longer than the other side, and the part can be folded back. Glue such as glue can be used to seal the bag when the plastic cover on the gel is peeled back.
