7 Layers Clear Food Vacuum Sealer Bags for Freeze Dried Foods

The 7 Layers Clear Food Vacuum Sealer Bags are specially designed for freeze-dried foods and other low-temperature storage applications. Constructed with a seven-layer co-extruded structure, these vacuum bags combine polyethylene (PE), polyamide (PA), and TIE adhesive layers, offering excellent flexibility, strength, and barrier properties. The advanced multi-layer design ensures that food products maintain freshness, aroma, and quality during storage and transportation.

These vacuum sealer bags are ideal for freeze-dried fruits, vegetables, meats, seafood, and sensitive pharmaceutical products, providing reliable protection against moisture, oxygen, and physical damage. Their superior low-temperature resistance makes them suitable for freezing as low as -40°C, while maintaining strong tear resistance and structural integrity.
