Applicable Materials
Low-density polyethylene (LDPE), Polypropylene (PP) - for manufacturing zipper chains.
Performance and Features:
The barrel and screw of the extruder are processed with special treatment, featuring optimal hardness and corrosion resistance.
Changing different molds allows the production of various types of zipper chains.
The machine completes the entire process from extrusion, mold shaping, constant temperature cooling water system, dehydration device, air-drying device, zipper buckling device, to automatic length/quantity calculation, automatic arranging and winding on the winding table, resulting in high-quality finished zipper chains.
The mold has a flexible structure for easy loading and unloading, and the machine is simple to operate.
PE, PP Zipper Extruder Application Scenarios
Thanks to the excellent ductility, food-grade safety and low processing cost of PE and PP raw materials, PE & PP zipper extruders deliver outstanding performance for manufacturing sealing strips of plastic flexible packaging and disposable self-sealing zipper profiles.
1. Food Self-sealing Bag Zippers: For snack bags, frozen food packages, fruit fresh-keeping bags and vacuum food storage bags, to extrude and form zipper strips.
2. Daily Storage Bag Zippers: For apparel packing zip bags, stationery storage pouches and cosmetic sample sachets, producing self-sealing zipper profiles.
3. Industrial Packaging Zippers: Anti-static PP zipper strips for electronic component bags and moisture-proof zipper profiles for hardware accessory packaging.
4. Agricultural Packaging Zippers: Sealing zippers for seed bags, small fertilizer pouches and fresh vegetable retail packing bags.
