The company's products cover 1-8 series of aluminum alloy products of different sizes, including automotive aluminum plates, food-grade aluminum foils, household aluminum foils, anodized aluminum plates, mirror aluminum plates, packaging aluminum foils, aluminum foil PP covering materials, DOS oiled aluminum sealing sheets, cookware aluminum rings, marine aluminum sheets, double zero aluminum foils, aluminum pattern sheets and other products.

Food grade aluminum foil is a specially treated aluminum material that can directly contact food without causing chemical reactions. This material is widely used in food packaging, storage, grilling, heating and other occasions that come into contact with food due to its high temperature resistance, moisture resistance and corrosion resistance.

Food grade aluminum foil also has a variety of grades, such as 8011, 3003 and 1235, each of which has different characteristics and scope of application, but together meet the safety and hygiene requirements of food packaging and cooking.

Features of food aluminum foil:

1. Lightweight and tough: Although aluminum foil is very thin, it has a certain mechanical strength and can withstand a certain amount of tension and compression.
2. Strong antioxidant properties: Aluminum foil can effectively block oxygen in the air to prevent food from oxidation and deterioration.
3. Good barrier properties: It can prevent the influence of external factors such as moisture, grease, and aroma on food, and extend the shelf life of food.
4. High and low temperature resistance: It can withstand environmental changes from extremely low temperature to higher temperature, so it is suitable for packaging frozen food or baked food.
5. Recyclability: Aluminum foil material is recyclable and meets environmental protection requirements.
‌

Application scenarios:
1. Uses of food-grade aluminum foil: widely used in the packaging of meat, dried fish, aquatic products, cured meats, roast duck, frozen foods, etc., effectively preventing moisture and oxidation, and maintaining the freshness and quality of food.
2. Cooking and grilling: often used to wrap food such as sweet potatoes and golden mushrooms to avoid burning and retain the freshness. It can be heated at high temperatures in ovens and microwave ovens without releasing harmful substances.
3. Food container production: can be used to make disposable aluminum foil trays and boxes, which are convenient for food storage and preservation, and have little impact on the environment.
4. Other applications: suitable for multi-layer composite bags, aseptic packaging boxes, etc., and are also widely used in pharmaceutical, electronic, and cosmetic packaging.
