CRYOVAC® brand hot water shrink tunnels provide a finishing step for food products that have been vacuum sealed into CRYOVAC® brand shrink bags. Using water that is pre-heated either by electricity or steam, the shrink process also serves to toughen the package material as well as provide a skin-tight fit that helps preserve colour and reduce purge.
- Uses hot water to shrink CRYOVAC® brand vacuum bags tightly onto food products
- Hot water process helps thicken and toughen material for improved package strength and product protection
- Typically used for fresh meat, seafood, poultry, cooked and processed meats, block cheese

Cold Water Chill Tunnels
Packaged food products that may be prone to bacterial growth or discolouration after exposure to heat should be re-chilled as quickly as possible after shrink. CRYOVAC® brand cold water chillers provide this critical step that is designed for use in USDA-inspected plants, as well as operations that export pork products to Japan.
