These 12" x 18" 4 Mil co-extruded vacuum seal bags are built for demanding food processing and industrial packaging environments where consistency and shelf life are critical. Designed for use with commercial chambered vacuum machines, these vacuum bags provide strong, uniform seals that help protect products during storage, handling, and distribution. Their generous 12" x 18" size nicely accommodates larger cuts of meat, bulk cheeses, prepared meals, and a variety of non-food products that require high-barrier packaging to maintain quality. Manufactured from multi-layer co-extruded film, these vacuum seal bags offer excellent clarity and strength while maintaining flexibility for efficient loading and sealing. The 4 Mil thickness enhances puncture and tear resistance, helping to safeguard sharp or irregularly shaped items under vacuum pressure. The high-barrier construction is ideal for extending shelf life and reducing dehydration, shrink, and odor transfer in refrigerated or frozen conditions.
