Stronger, thicker seals eliminate product loss, freezer burn, and dehydration while providing extra protection during transport and handling. High-clarity transparent Poly/nylon material makes product easily identifiable through the seal. Compatible with small and large vacuum chamber machines. Sous Vide, which means 'under vacuum' in French, is the process of vacuum sealing food and submerging it in a controlled-temperature water bath. This cooks food products more evenly and consistently with little work involved. NOT INTENDED FOR FOOD SAVER SEALERS.
