Aluminum Foil for Food Packaging
Aluminium foil, whether unsupported or laminated to paper and films, is now an almost mandatory material for flexible packaging in the food industry. Every consumer is familiar with household foil, but foil is also widely used in sachets and pouches, dairy lids, bottleneck foil, capsules, labels, seals and other applications.
Aluminum foil is not only cost-effective but also provides complete food protection. It is unrivaled as a barrier layer, completely excluding light, gases, oil and fat, volatile compounds and water vapor. Aluminium foil is temperature resistant, thermally stable and an extremely good conductor of heat. It is also strong, durable and safe for use in contact with all foodstuffs.
Aluminum foil is the main product in the packaging field, especially in the field of home food packaging. Among the wide variety of foods, different flavors, different brands, and a variety of shapes, many food packaging is made of aluminum foil and composite material. Among the many alloy products, 8011 aluminum alloy is the main product in household food packaging, 8011 aluminum foil for home packaging is widely used in food, such as some vacuum-packed cooked food, candy, high-end ice cream, barbecue aluminum foil, etc.
8011 aluminum foil has clean surface, uniform color, no spots, and no pinholes. At the same time, it also has excellent moisture resistance, shading and high barrier ability, strong mechanical properties, high anti-blasting performance and strong puncture and tear resistance, non-toxic, tasteless, safe and hygienic. The household aluminum foil 8011 can also be used as the raw material for food containers and medicine packaging, so in the packaging application, 8011 aluminum foil has many performance advantages. 8011 home packaging aluminum foil can be used for cooking in household, because it is recyclable, so it will have more consumption on the market. The thickness range of the aluminium foil for home packaging is 0.018mm-0.2mm, the width can be controlled to 100-1650mm according to customer’s requirements.
