Boxes, cartons, books, printed matter and retail packs usually require a clean seal line, controlled film presentation and a heat tunnel sized around the product dimensions. L-sealers and side sealers are common routes for this type of shrink wrapping.
Why pack dimensions matter
The product length, width and height determine sealing jaw size, tunnel aperture, film width and pack spacing. Tall or heavy products may need slower tunnel speed or a larger conveyor.
L-sealer and side-sealer routes
L-sealers are useful for presentation packs and moderate outputs. Automatic side sealers and heat tunnels suit longer runs, repeat products and higher throughput requirements.
Finish and film choice
Clear POF film is often used where pack appearance is important. PE film may be chosen for heavier or transit-focused applications. The tunnel must be matched to the film route.
