What are the applications of food composite bags?
Food composite bags are made of three layers of films of different materials combined through a composite process. The combination of these materials can provide excellent barrier properties, strength and printing performance, and is suitable for packaging a variety of food products.
1. Outer layer (printing layer): using BOPP (biaxially oriented polypropylene) to provide good printability and wear resistance.
2. Intermediate layer (barrier layer): Use aluminum foil (AL) to provide excellent barrier properties.
3. Inner layer (heat sealing layer): Made of PE (polyethylene), which provides good heat sealing performance and food safety, and is acid and alkali resistant to prevent food from deteriorating.
Food composite bag Application scenarios:
1. Snack packaging: such as potato chips, biscuits, candies, etc. These foods require good moisture-proof and oxygen-proof properties to maintain their crispness and freshness.
2. Coffee and tea: These products have high requirements for fragrance and freshness, so they require high-barrier materials to prevent the entry of oxygen and moisture.
3. Condiments: such as sauces, spices, etc. Such products usually have high requirements for packaging sealing and anti-corrosion, and three-layer composite bags can effectively extend their shelf life.
4. Meat products and seafood: These foods require strong barrier properties to prevent oxygen and bacteria from entering, ensuring the freshness and safety of the products.
5. Fast food: such as instant noodles, instant soup, etc. The three-layer composite bag can provide sufficient strength and heat resistance, suitable for microwave heating or hot water brewing.
6. Dairy products: such as milk powder, cheese, etc. Dairy products are very sensitive to light, oxygen and moisture, and three-layer composite bags can provide good protection.
7. Frozen food: such as frozen vegetables, fruits and meat. The three-layer composite bag can still maintain good flexibility and sealing properties in low temperature environments, preventing freeze burn and moisture loss.
8. Beverage powder: such as juice powder, sports drink powder, etc. Such products require moisture-proof and odor-proof packaging, and three-layer composite bags can effectively maintain their taste and nutritional content.
