Aluminum foil cannot be used alone and must be combined with plastic film. Aluminum foil food packaging bags are high-end packaging in the food industry. Aluminum foil food packaging bags have important features and advantages such as high temperature resistance, puncture resistance, and non-deformation.
The material of the aluminum foil packaging bag is made of a combination of PE/AL/PE/CPP. PE has good printing effect, strong AL barrier performance, and is opaque. The inner layer of PE ordinary packaging and the inner layer of CPP high-temperature cooking are used. When using aluminum foil, the purity of the material is very high, which must reach 99.99%, with almost no impurities. However, because of the small pores, aluminum foil is rarely used alone and must be bonded with plastic film.
Packaging bags made of aluminum foil are suitable for food, daily chemicals, machinery, electronics, lubricants and other industries. The main advantages of food packaging bags made of aluminum foil are as follows:
1. Resistant to high temperatures (up to 121 degrees) and low temperatures (minus 50 degrees). Some food packaging bags used for high-temperature cooking can use this material.
2. Good oil resistance and outstanding fragrance retention performance
3. Excellent barrier performance, strong air barrier performance, antioxidant, waterproof and moisture-proof
4. Good heat sealing performance and high softness
5. Use food packaging bags made of aluminum foil to package food, which is non-toxic, tasteless, healthy and safe and complies with national health standards.
Aluminum for food packaging mainly refers to aluminum foil, which is a commonly used food packaging material.
Aluminum foil has the following advantages in food packaging:
Barrier properties: Aluminum foil has excellent barrier properties against water, air (oxygen), light, and microorganisms, and can extend the shelf life of food.
Easy to process: Aluminum has a low melting point, good heat sealability, and is easy to form. It can be processed into any shape according to the mold.
Thermal conductivity: Aluminum is an excellent thermal conductor and can transfer heat quickly and evenly. It can be placed in ovens, grills, and refrigerators together with food.
Light weight: The thickness of aluminum foil is extremely small, which can achieve protective functions while minimizing the weight of the product, reduce transportation costs, and increase convenience of use.
Environmental sustainability: Aluminum foil has certain corrosion resistance, stable chemical properties, long packaging life, and can be recycled.
