These 18 x 28 3 Mil co-extruded vacuum seal bags are built for demanding commercial packaging applications where product integrity and shelf life are critical. Produced by International Plastics Inc., they feature multi-layer co-extruded film that delivers superior strength, clarity, and puncture resistance compared to standard single-layer bags. Their large 18 x 28 size is ideal for bulk proteins, large cuts of meat, cheeses, and other high-volume food products that require secure, air-tight packaging in busy processing environments. These commercial vacuum bags are specifically designed for use with commercial chambered vacuum machines and are not intended for at-home Foodsaver-style external suction units. The 3 Mil thickness provides an optimal balance of durability and flexibility, helping prevent leaks and seal failures during processing, storage, and distribution.
