Aluminum foil is increasingly used in cooking a variety of foods because it is easy to use, disposable, and conducts heat twice as fast as ordinary metals. As part of home cooking, household aluminum foil is used to wrap and bake foods.
The new household foil product is ultra-thin at 0.0063mm, which can be ultra-thinly attached to food to keep it fresh longer. Food, fruits and vegetables wrapped in ultra-thin household foil can be placed in the refrigerator to effectively reduce water loss by up to 89.3%, and keep it fresher.
Aluminum foil can also be used in situations where the temperature rises rapidly, such as baking and microwave heating. The high heat conduction efficiency also makes aluminum foil suitable for high-temperature and high-pressure sterilization, heat sealing and other high-temperature processing processes. In addition, when the temperature changes rapidly, the aluminum foil will not deform, crack or burn, affecting the texture or taste of the food itself.
At present, the aluminum alloys used to produce household foil on the market are generally 1235 and 8011 alloys. The use of Al 1235 to produce household foil has the advantages of good surface quality and few pinholes in the foil, but the strength is relatively soft; while when using 8011 alloy to produce household foil, although the strength is high and the rolling stability is good, it is easy to have excessive pinholes.
Food-grade aluminum foil not only needs to have high physical and chemical properties, but also needs to comply with relevant food safety and hygiene standards. Therefore, when conducting quality inspections on food-grade aluminum foil, it must be based on certain implementation standards, such as GB standards, ASTM, EN and ISO standards.
Food aluminum foil has undergone strict pinhole detection, oil removal process and plate shape control. The product safety and hygiene meet food-grade requirements, and has advantages such as high elongation. It is widely used in barbecue, baking, food packaging, etc.
Haomei food aluminum foil like 8011 aluminum foil roll has undergone multiple tests such as bacteria and mold. The heavy metal content does not exceed 0.25 parts per million. It strictly implements industry standards and meets food-grade aluminum foil standards, which is harmless to the human body.
