Seal
Sleeve sealer
Creates the film sleeve around the tray or bundle before the pack passes through the heat tunnel.

Tray shrink wrapping machines
Tray shrink wrapping machinery wraps collated products in film after they are placed into trays for improved stability and transport protection.
UK specification advice
Use trays where product stability matters
Trays can make multipacks easier to move through a shrink wrapping line, especially when products are tall, narrow or liable to move during transfer.
The shrink wrap machine must allow for the tray height, product height and total pack width so the sleeve and tunnel can process the full pack reliably.
Tray shrink wrapping is often used for bottles, cans, jars, cartons and mixed product bundles where transit protection is more important than a fully enclosed presentation wrap.
Machinery route
Tray shrink wrapping route
Tray packs usually combine product grouping, sleeve sealing and heat tunnel shrinking.
Shrink
Heat tunnel
Shrinks the film around the tray with controlled temperature, airflow and conveyor speed.

Tray pack specification notes
When specifying tray shrink wrapping machinery, include the tray dimensions as well as the product dimensions. The total pack size determines film width and tunnel aperture.
If trays are manually loaded, operator reach and loading height should be considered. For automatic lines, the tray packing process must feed consistently into the wrapper.
The film should be strong enough for handling but suitable for the heat tunnel settings and pack contents.
Common questions
Tray shrink wrapping FAQs
Why use a tray before shrink wrapping?
A tray improves pack stability and gives products a base before the film shrinks around the bundle.
Can tray packs use PE film?
Yes, PE film is commonly used for tray shrink wrapping and transit bundles.
What measurements are needed?
Provide tray length, width, height, product height, total pack weight and the desired pack count.
Can a tray shrink wrapper run different trays?
Many systems can adjust, but the machine must be sized for the largest tray and product combination.
