Alu foil 7 mic for lamination
Alu foil 7 mic for lamination is a high-grade printing and packaging material, which has the advantages of good insulation, impermeability to air and water vapor, In life, have you ever had such a question, can the aluminum foil bag be heated, and will it be toxic under high temperature? Can the aluminum foil bag be heated? It is more common to heat the milk packaged in the aluminum foil bag. In fact, this is possible. Its high temperature resistance can reach 120 degrees Celsius. When we heat it in water, it can only reach 100 degrees Celsius. Direct contact with aluminum foil is safe. Aluminum foil bags are not toxic at high temperature This poisoning process is not easy to detect and takes a long time. However, the melting point of aluminum is 660 degrees Celsius, and there is relatively little risk of precipitation during grilling. 2. Aluminum foil can not only transfer heat, but also prevent the meat from directly contacting the flame, which is equivalent to wearing a layer of "fireproof clothing" to reduce the chance of being scorched.
Alu foil 7 mic for lamination is Precautions for heating aluminum foil bags 1. The surface cleanliness of the aluminum foil should be high, there should be no oil stains and dust, and the surface tension should be high, which should reach more than 72mN/m. A simple method is to test with distilled water, which should be fully wetted on the surface of the aluminum foil. If the surface of the aluminum foil is seriously oily, it will affect the composite fastness of the aluminum foil and other materials, especially after the packaging bag is cooked at high temperature, the phenomenon of delamination and peeling will occur. 2. The number of pinholes in the aluminum foil should be less. Aluminum foil should be the material with the best barrier properties, but if it has pinholes, its barrier properties will be greatly reduced, gas and light will penetrate quickly and directly, and the contents will soon deteriorate. For example, the number of pinholes in the aluminum foil with a thickness of 7μm should be less than 200 holes/square meter; the number of pinholes in the aluminum foil with a thickness of 9μm should be less than 100 holes/square meter. square meters. No matter how thick the aluminum foil is, the pore size of the pinhole should not be larger than 20μm. 3. The texture of the aluminum foil should be soft, it should not be easy to break when folded, and it should have good toughness. The purchased aluminum foil should be stored in a dry state, and should not be stored for too long. It should be used as soon as possible to prevent the aluminum foil from deteriorating due to moisture absorption and oxidation. .
