Shrink Packaging
In shrink packaging the contents are vacuum packed in special shrink film or pouches. After brief contact with hot water, the film or pouch shrinks to enclose the product in a skin tight package.
- Cheese
- Fresh and processed meat
- Individual pack design possible
- Food retains its quality and freshness for much longer; leakage, from packed meat products for example, is prevented
- Attractive presentation of the product
Products are vacuum packed using a shrinkable packaging material (film or pouch).
After sealing the package is shrunk in hot water using a shrink tank or shrink tunnel. If the shrink packs are to undergo further processing (e.g. labelling) immediately, the use of a drying tunnel is advisable.
Machines:
- MULTIVAC thermoformers, chamber machines or conveyor belt machines
- Shrink tank (for smaller vacuum pouch packs) or shrink tunnel (SE 115 for thermoformers or SE 130 for conveyor belt machines)
- Dryer (optional) for seamless further processing, e.g. labeling or cartoning (TE 115 for thermoformers or TE 130 for conveyor belt machines)
