Hot Welding Sealing PET Strap Extrusion Line 120-180kg/h 65-75mm Screw Automatic

The Hot Welding Sealing PET Strap Extrusion Line is a compact, affordable solution for small and medium strap producers. Available with a 65mm or 75mm single screw, the line runs at 120-180kg/h and includes an automatic control system, water cooling and a hot welding sealing unit that produces strong, reliable coil joints. It is easy to operate, easy to maintain and quick to install, making it an ideal first extrusion line or a flexible addition to an existing strap factory that needs extra capacity for PET strap and PP strap orders.

• Hot Welding Sealing: The integrated hot welding unit fuses strap ends into smooth, high-strength joints that run cleanly through automatic strapping machines without jamming.
• 120-180kg/h Flexible Output: Output can be adjusted across the 120-180kg/h range to match order sizes and downstream winding capacity.
• 65-75mm Screw Options: Choose a 65mm screw for lighter duty or a 75mm screw for higher throughput, both machined from durable 38CrMoALA steel.
• Automatic Control: Automatic temperature and speed regulation keep the line stable with minimal supervision, reducing labor cost per kilogram.
• Easy To Operate: Straightforward layout and simple controls mean one operator can manage the whole line after a short training period.
• Water Cooling System: Efficient water cooling protects the screw and barrel, stabilizes melt temperature and extends the service life of wear parts.

This line is perfect for producers serving local and regional markets with PET strap and PP strap for carton sealing, brick packing, textile baling, wood bundling and general logistics. The hot welding sealing unit adds value by delivering ready-to-use coils, and the automatic control system keeps product quality consistent even with less experienced operators. Because the line accepts both PP and PET materials and offers customized color options, converters can quickly respond to changing customer demands. The compact design and easy installation make it particularly attractive for startups and expanding workshops.

Every line is packed in sturdy wooden export cases with stretch film wrapping, foam cushioning and clear handling marks. Machines are run under no-load conditions and fully inspected for electrical safety, mechanical alignment and safety device function before shipment. We provide an English operation manual, installation video, free online support and optional on-site commissioning by our engineers. Sample straps, test videos and inspection reports can be supplied on request, so you can evaluate the machine quality before it reaches your factory.
