What are Aluminum Packaging Advantages

Food packaging aluminum foil It protects food against light, oxygen, moisture, bacteria and harmful odors. How to produce quality aluminum foil packaging? Haomei Aluminum tells you how aluminum foil is produced.

Aluminum foil can be divided into industrial aluminum foil and aluminum foil packaging. The chemical composition of industrial aluminum foil is relatively pure, and the thickness is 0.005-0.2 mm. It is mainly used as capacitors, heat insulation materials, and moisture-proof materials in the electrical and electronic industries. Packaging aluminum foil thickness is generally 0.007 ~ 0.1 mm.

Food packaging aluminum foil acts as a reliable barrier. It protects food against light, oxygen, moisture, bacteria and harmful odors. Therefore, food and pharmaceuticals in aluminum packaging greatly increase their shelf life. Scientific research has shown that aluminum foil with a thickness of 6mm can be considered an absolute barrier. For example, milk is sterilized so that it has a long shelf life even without refrigeration.

Aluminum foil has high conductivity and can minimize the time and energy associated with food processing, refrigeration and reheating. Aluminum foil has good thermal stability. In the process of processing and packaging, aluminum foil containers can well withstand temperature changes. Under the high and low temperature of -20°C-250°C, the molecular structure is stable and does not change. Aluminum foil container can be heated in various ways, including various ovens, heating cabinets, steamers, microwave ovens (be sure to use light waves and grills), and pressure cookers.

The minimum thickness of aluminum foil produced by the belt production method can reach 0.0025 mm and the width can reach 1800 mm. Aluminum foil rolling is rolling without roll gap, and the rolls are always in a state of elastic flattening. During rolling, the thickness of the aluminum foil can be controlled by adjusting the rolling force, rolling speed and controlling the tension.

During rough rolling, the rolling force is used to control the thickness of the foil; during finish rolling, the thickness of the foil decreases as the rolling speed increases; the greater the tension, the smaller the thickness. In order to prevent breaking, the tension selection is usually 0.2 to 0.4 of the conditional yield strength of aluminum foil. During low-speed rolling, "thick oil" or "thin oil" is often added to the lubricating oil to adjust the rolling thickness of the aluminum foil.
