Why the shrink tunnel matters

The shrink tunnel is responsible for the final film finish. Even when the sleeve sealer is correctly specified, the pack can look poor if the tunnel aperture, temperature zones, airflow or belt speed are mismatched.

For PE shrink film and multipack applications, tunnel settings need to be matched to pack size, film thickness and required output. Belt speed and spacing affect how long the pack receives heat and how consistently the film shrinks.

Quick answers

Sleeve sealer FAQs

What does a shrink tunnel do?

A shrink tunnel applies controlled heat so shrink film tightens around the pack after the sleeve has been sealed.

Can one shrink tunnel handle all pack sizes?

Not always. Tunnel aperture, airflow, belt speed and heat capacity must match the largest pack and required output.

What causes poor shrink finish?

Common causes include unsuitable film, incorrect temperature, poor airflow, wrong belt speed or insufficient pack spacing.
