Why Is Aluminum Foil Packaging So Popular?

In recent years, aluminum foil packaging is more and more popular due to its series of excellent properties. It has a low density, only 1/3 of steel, excellent processability and is easy to punch into various complex shapes. It has strong corrosion resistance and will not rust. It has excellent barrier properties, light-shielding properties, and fragrance retention, which can effectively protect product. It is easy to print and has good printing effect. The common alloys are 8011, 8021 and 8079 aluminum foil roll.

Aluminum packaging materials mainly include pure aluminum plate, alloy aluminum plate and aluminum foil. Aluminum alloy plate is processed by adding a small amount of magnesium, manganese and copper to aluminum. Aluminum alloys commonly used in packaging include aluminum-magnesium alloys and aluminum-manganese alloys, also known as anti-rust aluminum alloys.

The aluminum alloy sheets are mostly used to make canned containers. When used for canned fish and meat, they will not be vulcanized and blackened like tinned cans; they are more used for packaging beverages, which will not make the beverages muddy and flavor changes.

Aluminum foil is made of pure aluminum with a purity of more than 99.5% by rolling, and the thickness is between 0.005 and 0.2mm. It is light and shiny, has strong reflective ability, and can be used as heat-proof and insulating packaging. The biggest disadvantage of aluminum foil is that it is not resistant to acid and strong alkali and has low tear resistance.

Aluminum foil can be used to package items alone; more often it is made of composite materials with paper, plastic film, etc., used for packaging of food, cigarettes, cosmetics, medicines, chemicals, etc.

The exporting packaging of aluminum foils should be based on the specifications and dimensions of the product. The making material of packing box can be materials such as wood board, plywood, fibreboard, metal. The packing box should be clean and tidy, and have enough strength to ensure that it will not be deformed or damaged during storage and transportation of aluminum foil like 8021 aluminum foil.

The nails in the wooden packing box are arranged step by step, and the nail tips should not be exposed. The height of the bottom bracket should meet the requirements of forklift transportation. After the aluminum foil product has passed the inspection and is covered with inspection stamps, it should be wrapped with a layer of strong neutral or weakly acidic material, and the joints should be sealed with tape or labels. We also should pay attention to the protection of end face and the moisture-proof problem.
