Advantages of Aluminum Foil in Food Packaging Area

Aluminum foil has the following advantages in food packaging:

Barrier properties.
Aluminum foil has excellent barrier properties against water, air (oxygen), light, and microorganisms, all of which are important factors in food spoilage. Therefore, aluminum foil has good protective functions for food.

Easy to process. Aluminum has a low melting point, good heat sealing properties, and is extremely easy to form. It can be processed into any shape according to the mold. The processed aluminum foil has excellent ductility and can be applied to food of different shapes. It is also easy to carry out surface treatment, such as embossing technology, which can make aluminum foil more beautiful and promote consumption.

Thermal conductivity. Aluminum is an excellent thermal conductor that can quickly and evenly transfer heat, and can be placed together with food in ovens, grills, and refrigerators.

Lightweight. The thickness of aluminum foil is extremely small, which can achieve protection function with minimal increase in product weight. Lightweight packaging can reduce transportation costs and increase convenience of use.

Environmental sustainability. Aluminum is the most abundant metallic element in the Earth's crust and the third most common material with a wide range of sources. Aluminum foil has certain corrosion resistance, stable chemical properties, and a long packaging life. Recyclable and recyclable, with a cycle energy consumption of only 5% of the original production, is an economical and sustainable choice.

Regarding the selection of aluminum foil, different thicknesses of aluminum foil are suitable for the following categories of food: 10-12 μ M is suitable for chocolates, candies, etc. 30-38 μ M is suitable for the dairy industry, such as pudding, yogurt, etc. 50-70 μ M is suitable for jam, meat products, etc. It should be noted that aluminum foil is not suitable for packaging food with strong acidity or strong salty taste, such as food containing vinegar or fruit acid, pickled Chinese cabbage, rhubarb, salted fish, etc., which may cause chemical reaction to cause aluminum ions to enter food.

The available material combinations include VMPET/PE, PET/AL/PE, OPP/AL/PE, PA/AL/PE, PET/AL/PA/PE
