Transit packs need containment
For transit packaging, film strength and pack stability are often more important than decorative presentation. A sleeve sealer with PE film and a shrink tunnel can be a practical route for grouped products.
Common applications include cartons, trays, bottles, cans, tubs, boxes and other products that need to move as a single pack.
Machine route options
The correct transit shrink wrapping machine depends on output and collation. Operator-assisted sleeve sealing can suit lower volumes, while automatic sleeve sealers are better for repeated production packs.
Side-feed or inline systems may be chosen according to how the products arrive and how the bundle needs to be formed before shrink wrapping.
What affects the finished pack
The final result depends on film width, overlap, tunnel heat, airflow and dwell time. Pack shape and weight also affect the tunnel transfer and outfeed handling.
Providing pack data and photographs allows Lancing to advise on the machine route and avoid under-specifying the tunnel or conveyors.
