At present, there are many packaging materials on the market, such as plastic, paper, glass and aluminum household foil. They are compared in terms of environmental protection, high temperature resistance, water resistance, oil resistance, and low price.
Plastic is a chemical material, and most of it releases toxic substances when the temperature is too high. In addition, there are more white garbage in daily life, so plastic has disadvantages in high temperature resistance and recycling.
In contrast, paper can be recycled, but it has certain shortcomings in terms of high temperature resistance, heat preservation, and oil resistance. The fatal weakness of glass packaging is that it is fragile, so there are great disadvantages in the process of transportation and storage. Currently, it is mainly concentrated in beer and beverages, and developed countries have gradually reduced glass beer packaging.
Aluminum foil packaging can meet multiple requirements such as easy recycling, environmental protection, water resistance, and high temperature resistance. There are two main applications of aluminum foil in food packaging: one is aluminum household foil and aluminum foil tray, the other is aluminum composite packaging material, namely Tetra Park.
Household food packaging aluminium foil widely used in cooking, freezing, fresh-keeping, baking and other industries. In the refrigerator or freezer, the aluminum foil can be directly wrapped on the food, which can keep the food from being deformed, and can prevent the water loss of fish, vegetables, fruits, and dishes, and prevent the taste from leaking or mixing.
The household aluminum foil price usually depends on alloy grades, specifications, technical requirements and dosage. Among them, the alloys are 8011/H22, 8011/H24, 8011O, 3003/H24 aluminum foil. Generally 3xxx aluminum foil price is higher than that of 8xxx aluminum foil.
The food aluminum foil usually chooses light gauge foil. Different thicknesses have different prices. Generally, the thinner the thickness, the higher the price. As for the performance, it should have high tensile and elongation strength.
