These 16" x 20" 5 Mil co-extruded vacuum seal bags are heavy-duty, commercial-grade packaging solutions designed for demanding food processing and industrial environments. Manufactured from multi-layer co-extruded film, these vacuum bags provide a strong barrier against moisture and oxygen to help extend shelf life and maintain product integrity. They are ideal for portioning bulk proteins, cheeses, prepared foods, and other perishable products where secure, airtight packaging is critical. Engineered specifically for use with commercial chambered vacuum machines, these vacuum seal bags are not intended for at-home Foodsaver-style external suction machines. The 5 Mil thickness delivers excellent puncture and abrasion resistance, making them suitable for products with sharp edges or bones, while still offering flexibility for efficient loading and sealing.
