Multipack shrink wrapping requirements
Multipack shrink wrapping is different from wrapping a single retail item. The machine must handle a group of products, maintain the collation, apply the correct film sleeve and shrink the film without distorting the pack.
For bottles and cans, pack stability, product diameter, product height and the required collation pattern affect the sleeve sealer and shrink tunnel specification. For trays and cartons, the important details are pack footprint, product edges, film overlap and tunnel presentation.
Common multipack formats
- Bottled drinks and water multipacks.
- Can multipacks and beverage trays.
- Grouped cartons, tubs or containers.
- Transit packs using PE shrink film.
- Tray and trayless bundles for storage or distribution.

| Bundle | Count, layout, tray use, target finish and pack handling after the tunnel. |
| Production | Required packs per minute, changeovers, operators and available space. |
