When aluminum foil is used in food packaging, it has the functions of preserving fragrance, color, taste and quality, which mainly depends on the characteristics of aluminum foil such as high barrier property, light resistance, high temperature resistance, low temperature resistance, oil resistance, water resistance,etc. Because of these almost perfect advantages, it is very popular in the food packaging industry.
At present, container aluminum foil that can be heat-sealed and sterilized by high temperature and high pressure are also widely used in pies, luncheon meat, cans, sauces, jams, processed cheese, coffee milk, vegetarian paste and other products that require a long shelf life.
Although it has so many advantages, the high price restricts the development of aluminum foil. Taking aluminum food tray for example. The price of a 20-gram aluminum foil container on the market is about 0.75 RMB, the recycling price is 0.2 RMB, and the actual use cost is about 0.55 RMB. However, the cost of foamed plastic container is less than 0.1 RMB. Therefore, the competitive advantage of aluminum foil packaging in food packaging is mainly concentrated in the middle and high-end food, and the fields that require relatively high heat resistance.
The alloys of aluminum foil for food container are 3003, 3004, 8011, 8006, 5052,etc. Most of the early domestic aluminum container used 3003 plain aluminum foil. Later, in order to reduce costs, 8011 alloys also began to be used in aluminum foil tray. 3004 aluminum foil has high hardness and good load-bearing. The stamping effect is better than 3003 aluminum foil. It can be applied to aluminum foil tray.
Haomei plain aluminum foil is clean, free of oil stains, bright lines and other inclusions. The products have undergone strict void detection, degreasing process and plate shape control. The hygiene meets food-grade requirements and has a high elongation rate. Welcome to leave message below to inquire what you need.
