These VacMaster RE‐THERM Pouches are meant for use with re‐thermalizing food and the heavy‐duty side seams are designed to endure long boiling times to preserve the quality of food inside the pouch. These pouches can stand up to 212°F for 30 minutes and can be reheated at high temperatures. These high barrier nylon / polyethylene pouches can be frozen, refrigerated, microwaved or used as boilable soup bags and are BPA free. These pouches work in conjunction with any chamber machine, but are intended for use with all VacMaster® VP Series Chamber Vacuum Sealers.
