FAQ

Shrink wrap seal wire spares FAQs

What information should I send?

Send the machine model and serial number, photographs of the existing wire and seal bar, the wire type and length if known, and the film type and gauge. Describe whether the fault is breakage, sticking, a weak seal or burn-through so the correct consumable can be checked.

Can Lancing UK advise on the right machine?

Yes. Lancing UK can review whether an L sealer, chamber sealer, sleeve sealer, heat tunnel or wider shrink wrapping line is the correct route.

Does the film type matter?

Yes. Film type, gauge, width and perforation affect seal quality, tunnel settings and final pack appearance.
