Product Description
plastic zipper extruder Product Selling Points
plastic zipper extruder
• High speed 20-60 m/min – Continuous production. Output up to 3,600 meters per hour.
• Wide zipper range – Width from 3mm to 100mm. One machine covers small zippers for snack bags to large zippers for storage bags.
• Triple screw design – Main 45mm screw + two 30mm co-extruder screws. Better mixing and melting of LDPE/PP.
• Complete inline system – Extrusion → water cooling → dewatering → air drying → zipper closing → length counting → automatic winding. No secondary equipment needed.
• Quick die change – Change molds in under 30 minutes. Produce different zipper profiles (single track, double track, interlocking).
• PLC + touch screen control – Set temperature (7 zones), speed, length, and batch count. Digital display.
• Energy efficient – Total power 15kW, heating 7kW, main motor 5.5kW. Inverter control saves electricity.
• Durable screw & barrel – Special hardening treatment for corrosion resistance and long life.v

Product Details
PLC Control Panel
It is the central operation hub of the zipper profile extruder machine. The touch screen lets operators set extrusion speed, temperature, output parameters and production data. The emergency stop, start/stop buttons ensure safe, precise control of the whole extrusion process for your plastic zipper extruder.
Tension Control Rollers
These rollers feed raw LDPE film or zipper profile material smoothly, maintain constant tension, and prevent wrinkling, skewing or misalignment during extrusion. They ensure stable, continuous material supply for your PE zipper making machine, guaranteeing uniform zipper profile quality and consistent production efficiency.
Molding & Cooling Unit
- Special die head molds precise zipper profiles with uniform thickness.
- Cooling system shapes zippers quickly and maintains stable shape.
- It supports zipper width 3–100mm and thickness 0.1–0.3mm for your PE zipper making machine.
Traction & Synchronized Speed Control
Application Range
- Plastic Packaging Material Factories:These factories produce self-sealing zip lock bags, storage bags, and garment bags in bulk. They use the zipper profile extruder machine to make high-quality LDPE zipper profiles, then assemble them into finished bags. This machine is their essential equipment to ensure stable zipper quality and mass production.
- Self-Sealing Bag & Zip Lock Bag Manufacturers:Factories that specialize in making zip lock bags, food storage bags, and household organizing bags rely on this plastic zipper extruder. They use the extruded zipper strips to produce complete self-sealing bags, which are sold to supermarkets, e-commerce sellers, and packaging distributors.
- Food Packaging Manufacturers:Food packaging companies use this PE zipper making machine to produce food-grade zip lock strips for snack bags, frozen food bags, and fresh-keeping bags. The machine processes LDPE material that meets food safety standards, making it ideal for food packaging production lines.
- Garment & Textile Packaging Factories:Garment factories and textile packaging plants use the LDPE zipper extruder to make zipper strips for clothing packaging bags, underwear bags, and fabric storage bags. The durable zipper profiles protect garments from dust and damage during transportation and storage.
- Small & Medium Packaging Processing Plants:Small to medium-sized packaging workshops and processing plants choose this compact zipper profile extruder for its low investment and high return. They produce custom-size zipper strips for local businesses, small bag manufacturers, and retail packaging suppliers.
- Industrial & Electronic Component Packaging Suppliers:Factories that make packaging for hardware parts, electronic components, and industrial products use this machine to produce heavy-duty zipper profiles. The extruded zippers create secure, moisture-proof packaging for sensitive industrial goods.
