End-of-line seal & cut — and the OEM view.

At the end of film blowing and converting lines, somebody has to seal and cut — bags on the roll, linings, sheet cut-off. We build that function two ways: as equipment for end users, and as a component that machine builders integrate into their own machines.

The job at line end

Line-end sealing is cyclic by nature: seal, cut, advance, repeat — against a line that keeps producing. The knife system has to keep seal quality constant across a shift, cope with the film range the line actually runs, and recover cleanly after a film change or a stop. That's a control problem as much as a heating problem, which is why the knife and controller ship as one matched system.

For machine builders

We supply OEMs the same hot-cutting knife systems we build into our own equipment, with the integration work done properly:

  • Mounting interfaces
    Blade carrier and station dimensions matched to your machine's sealing position — from photographs and dimensions, not assumptions.
  • Control integration
    Manual 0–10 current setting for operator-tuned lines, or remote setpoint driven by your PLC; status and fault signals available.
  • Documentation
    Interface drawings and I/O descriptions your engineers can work from — in English if your line goes overseas.
  • Random & aftermarket spares
    A first-year spares list classified by downtime risk, and repeat supply of wear parts for machines already in the field.
    Talk to us about terms.

What we need from you

  • Film
    Structure (PE, PP, laminate), width and thickness range.
  • Cycle
    Seal/cut cycle rate and whether line speed varies.
  • Interface
    Mounting points, available space, control signal preference.
  • For OEMs
    Estimated annual volumes — both machines and spare knives — so we quote the program, not just the unit.

Building machines that need a sealing end-station?

Send the film range, cycle, and mounting situation — we'll come back with the configuration, interface drawings, and an OEM spares program on request.
