Tightening PE zipper is a special PE zipper that fits most food packaging laminated films. The heat sealing temperature is moderate. The open side feels tighter, and the other side feels stronger. The main feature is the ability to provide a stronger seal and a better sealing effect on the bag. This type of zipper is often used in situations where a high degree of sealing and protection of the contents is required.
