Food pack shrink wrapping

Food shrink wrapping machine

Food shrink wrapping projects can involve individual cartons, trays, sleeve packs, multipacks or retail display packs. The correct machine depends on product stability, whether the pack is fully enclosed, and whether the shrink wrap is for presentation, grouping, tamper evidence or transit protection.

Choosing the correct food shrink route

  • L sealer and tunnel for boxed food cartons and retail presentation packs.
  • Sleeve sealer and tunnel for grouped trays, bottles, cans or multipacks.
  • Chamber sealer for low-volume batches and smaller boxed products.
  • Special handling where the product is unstable, light, chilled or heat-sensitive.

Film and tunnel considerations

POF film is often used where a clear retail presentation is required. PE film may be considered for stronger grouped packs. Heat tunnel settings must be matched to the film and pack so the finish is consistent without excessive heat exposure.

Production-line questions

Confirm pack size, product temperature, output, upstream filling or packing equipment, available floor space and whether operators need manual loading or automatic infeed.

Specification summary

For a reliable recommendation, send product dimensions, photographs, required output, film preference, available floor space, power and compressed air details. Lancing UK can then check the correct machine aperture, heat tunnel size, conveyor layout and operator access before quoting.

FAQ

Food shrink wrapping machine FAQs

Which shrink wrapper is best for food cartons?

Food cartons are commonly suited to L sealers and heat tunnels where a clear presentation shrink wrap is required.

Which machine is best for multipack food trays?

Sleeve sealers are often more suitable for grouped trays and multipacks because they can wrap a sleeve around the pack before tunnel shrinking.

Can food products go through a heat tunnel?

Many packaged food products can, but heat sensitivity, dwell time and film type must be reviewed before specification.
