POF and PE shrink film used with L sealer machinery — POF vs PE shrink film for L sealers guidance from Lancing UK.

POF shrink film

Often used for clear retail presentation packs.
Suitable for many boxed goods, books, cartons and light products.
Requires appropriate sealing and tunnel settings for a neat finish.
Common with L sealer and chamber sealer applications.

PE shrink film

Often used where pack strength is more important.
Common in sleeve wrapping and grouped pack applications.
Requires a tunnel suited to the film thickness and pack size.
May be considered for heavier products, trays and multipacks.

Why the machine must match the film

The sealer, tunnel aperture, belt speed and heat control need to suit the film. A film that works on one pack format may give a poor result on another if heat or sealing conditions are wrong.
