Performance and Features

Quad-Lane Production Power: Operates with a unique double-layer structure running 4 lines simultaneously. This configuration delivers massive output scaling up to several hundred bag pieces per minute, driving down your cost-per-bag to an absolute minimum.
Motorized Automatic Roll Lift: Say goodbye to hydraulic jacks and manual strain. The rear unwinding station features an electric smart-hoist assembly that lifts massive jumbo film rolls into place at the push of a button.
Floating Roller Tension Control: Outfitted with a highly responsive dancer-cylinder floating roller network that dampens film vibration and dynamically stabilizes web web tension across all 4 lanes simultaneously.
Industrial Thermal Heat-Sealing: Employs a heavy-gauge sealing bar with dual-zone micro-temperature control to execute consistent, leak-proof bottom seals on structural HDPE, LDPE, and eco-friendly films.
High-Speed Cold Cutting: Paired with a heavy-duty mechanical flying knife that precisely sheers the heated plastic tubes under zero-tension conditions, generating completely uniform, non-warped bottom edges.
Smart Multi-Language Controller: A central PLC command station manages bag length, production batch counters, and fault alarms with a simple interactive touchscreen supporting English, Spanish, Arabic, Russian, and Turkish.
