These 6" x 15" 3 Mil co-extruded vacuum seal bags are built for high-performance use in commercial chambered vacuum machines. Engineered with a multi-layer co-extruded film, they deliver excellent oxygen and moisture barrier properties, helping extend product shelf life and maintain product integrity. Their 3 Mil thickness offers a strong balance of durability and flexibility, making them suitable for packaging meats, cheeses, prepared foods, and other moisture- or aroma-sensitive products in demanding foodservice and industrial environments. As commercial vacuum bags, they are specifically designed for chamber vacuum sealers commonly found in restaurants, processors, and institutional kitchens, and are not intended for at-home Foodsaver-style external suction machines. The smooth, professional-grade construction ensures consistent seals, reduced leaker rates, and reliable performance in high-volume packaging operations.
