These 8" x 15" 3 Mil co-extruded vacuum seal bags are engineered for demanding commercial food packaging environments. Designed specifically for use with commercial chambered vacuum machines, these commercial vacuum bags are not compatible with at-home Foodsaver-style external suction units. The 3 Mil co-extruded film provides excellent strength and puncture resistance for products such as fresh meats, cheeses, prepared meals, and sous vide items, helping protect inventory through storage, handling, and distribution. Manufactured from multi-layer co-extruded material, these vacuum seal bags deliver superior oxygen and moisture barrier performance, extending shelf life and maintaining product quality and appearance.
