Manufacturing Process

Automatic roller changer — continuous rewinding with meter-count roll change

Unwinding

Feeds jumbo film from the unwind stand with tension control and EPC tracking for stable, wrinkle-free material supply.

Hot Slitting

Slits a wide jumbo roll into multiple narrow lanes inline before bag forming begins.

Sealing & Fly Cutting

Servo flying-knife bottom seal and cut-off for heavy-duty flat bags at high line speed.
