CRYOVAC® brand shrink tunnels are part of the automated process that provides a skin-tight final package. When combined with our CRYOVAC® brand shrink bags, the end result is a better protected and more visually appealing product. For applications that require cooling prior to distribution or the next process step, we also offer a chill tunnel that removes heat immediately after the shrink process.
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 color and reduce purge.
