Product Overview: Vacuum Sealed Food Bags
Vacuum sealed food bags are critical for preserving the flavor, texture, and nutritional value of perishable products by removing oxygen and creating an airtight barrier. Key applications include:
- Meat & Poultry: Fresh cuts, marinated meats, and cured products.
- Seafood: Fish fillets, shrimp, scallops, and smoked salmon.
- Dairy & Cheese: Block cheese, sliced products, and artisanal varieties.
- Ready-to-Eat Meals: Sous-vide dishes, pre-cooked meals, and frozen vegetables.
- Dry Goods: Coffee beans, nuts, and spices.
Core Advantages:
- Oxygen Barrier: Extend shelf life by up to 5x compared to conventional packaging.
- Leak-Proof Seals: Maintain vacuum integrity during transportation and storage.
- Temperature Resistance: Perform flawlessly from -50°C to 121°C (autoclavable).
- Sustainability: Recyclable and mono-material options available.
