These 12" x 15" 3 Mil co-extruded vacuum seal bags are built for demanding commercial environments where product integrity, shelf life, and consistency matter. Manufactured from high-barrier co-extruded film, they provide excellent oxygen and moisture resistance, helping preserve flavor, color, and texture for meats, cheeses, prepared foods, and more. Each case contains 500 commercial vacuum bags, giving processors, kitchens, and packaging operations a cost-effective solution for medium-duty vacuum packaging applications. Designed specifically for use with commercial chambered vacuum machines, these vacuum seal bags are not compatible with at-home FoodSaver-style external vacuum sealers. The flat, smooth construction and consistent 3 Mil thickness ensure dependable seals and rapid cycle times in chamber machines, helping streamline throughput in meat processing plants, restaurant commissaries, institutional kitchens, and co-packing facilities.
