Plastic Zipper Bag Blowing Machine

The plastic zipper bag blowing machine is a professional and specialized film extrusion equipment dedicated to producing high-quality plastic zipper film for various self-sealing zipper bags. It is specially optimized for the processing characteristics of zipper bag materials, realizing integrated automatic film blowing, cooling, shaping and winding. 

Adopting optimized upward blowing process and intelligent constant temperature control system, this automatic zipper film blowing machine ensures uniform plasticization and stable bubble operation during continuous production. The equipment is equipped with professional zipper dedicated die head, high-efficiency air cooling system, closed-loop tension traction unit and automatic winding system. Each functional module is precisely matched to realize one-time integral molding of the zipper tooth structure. It effectively avoids common defects such as unclear zipper lines, uneven film thickness and inconsistent hardness that easily occur on ordinary film blowing machines.

Our machines are packed with seaworthy export standard. Each unit is wrapped by PE stretch film, cushioned with foam, and securely fixed on ISPM‑15 wooden pallets. Spare parts and documents are separately packed. Firm lashing inside container effectively prevents moisture, dust, scratches and collision during long‑distance sea freight, guaranteeing intact machine arrival.
