These 12" x 14" 4 Mil co-ex vacuum seal bags are heavy-duty packaging solutions engineered for demanding food processing, industrial, and packaging operations. Manufactured with a multi-layer co-extruded structure, these vacuum bags provide outstanding barrier protection against oxygen and moisture, helping to extend shelf life and maintain product quality during storage and distribution. Their generous 12" x 14" size accommodates a wide range of products, from portioned meats and cheeses to bulk prepared foods and non-food industrial items, making them highly versatile in commercial environments. Designed specifically for use with commercial chambered vacuum machines, these vacuum seal bags are not compatible with at-home FoodSaver style external suction units. The smooth co-ex interior and robust 4 Mil thickness ensure consistent, reliable seals under high-vacuum conditions, reducing the risk of seal failures, leaks, and product loss.
