Aluminium products food-grade packaging

Aluminium products food-grade packaging refers to the food safety standards, specifically for the packaging of food aluminium materials and products, the following from the common types, features and applications for you:

Common types

Aluminium foil packaging: thin sheets processed from pure aluminium or aluminium alloy, with a thickness generally between 0.006-0.2mm. It can be divided into single-zero foil and double-zero foil, single-zero foil is commonly used in general food packaging, such as candy, chocolate, bread, etc.; double-zero foil is mainly used for high-end food, pharmaceutical packaging and some packaging areas that require high barrier properties, such as aseptic packaging, flexible packaging cans.

Aluminium can packaging: common cans and two-piece cans. Easy-open cans are usually used for packaging carbonated beverages, beer and other liquid foods, while two-piece cans are widely used in the field of beverages and canned foods, such as canned fruits, canned meats and so on.

Aluminium box packaging: Available in various shapes and sizes, it can be used to package food such as pastries, cooked food and fast food. Some high-end baked goods are often packaged in aluminium boxes, which can better maintain the shape and taste of the food.

Features

Good barrier property: Aluminium has good barrier property, which can effectively block the influence of oxygen, water vapour, light, etc. on food, preventing oxidation, moisture and deterioration of food, and prolonging the shelf life of food. For example, crisps packed with aluminium foil can well maintain the crispy taste of crisps.

Strong corrosion resistance: Aluminium is easy to react with oxygen in the air, forming a dense layer of aluminium oxide film on the surface, which can protect aluminium products from corrosion of acids, alkalis, salts and other substances in the food, ensuring the safety of food.

Good thermal conductivity: Aluminium has good thermal conductivity, so that the food inside the package is heated evenly, and it can be used for some food packages that need to be heated, such as aluminium foil baking trays and aluminium fast food containers, etc. It is convenient for the food to be heated up quickly in ovens, microwave ovens and other equipments.

High recyclability: Aluminium is a recyclable material, and the energy consumption of recycling is only about 5% of the energy consumption of primary aluminium production, which is conducive to environmental protection and resource recycling.

Application Areas

Baked food packaging: Aluminium baking trays, cake moulds, etc. can make the baked food heat evenly, and the baked bread, cakes, etc. have even colour and soft texture. Aluminium foil packaging of mooncakes can effectively maintain the flavour and taste of mooncakes and extend the shelf life.

Beverage packaging: aluminium cans are one of the main packaging forms for carbonated drinks, beer and other beverages, with the advantages of lightweight, easy to carry and good sealing.

Convenient food packaging: Aluminium fast food boxes, bento boxes, etc., widely used in takeaways, airline meals and other fields, not only to maintain the temperature of the food, but also has a good seal to prevent food leakage.

Frozen food packaging: Aluminium foil and boxes can be used to package frozen food, such as frozen dumplings, soup dumplings, etc. They can maintain good performance in low-temperature environments and prevent food from frostbite.
