At present, in the process of accelerating the upgrading and transformation of various industries, efforts have also been made in environmental protection construction. In addition to eliminating high energy-consuming and high-polluting products and replacing them with environmental protection equipment, packaging materials have also begun to be simplified and reusable, and aluminum packaging has become popular.

As a kind of white light metal rich in resources, the output of aluminum is second only to steel, and its application in the packaging industry ranks first among non-ferrous metals. Aluminum is used as a packaging material, and aluminum sheets, blocks, foils, and aluminized films are generally used.

➤Aluminum plate is usually used as can-making material or lid-making material;

➤Aluminum blocks are used to make extruded and thin-drawn cans;

➤Aluminum foil is generally used to make moisture-proof inner packaging or to make composite materials and flexible packaging.

The performance characteristics of aluminum packaging:

Excellent mechanical properties and high strength of aluminum packaging materials

Therefore, aluminum packaging containers can be made into packaging containers with thin walls, high compressive strength and not easy to break. In this way, the safety of the packaged product has a reliable guarantee, and it is convenient for storage, carrying, transportation, loading and unloading and use.

Excellent processing performance of aluminum packaging materials

The processing technology is mature, and it can be produced continuously and automatically. Aluminum packaging materials have good ductility and strength, and can be rolled into sheets and foils of various thicknesses. The sheets can be punched, rolled, stretched, and welded to form packaging containers of different shapes and sizes; Therefore, metal can give full play to its excellent and comprehensive protective performance in various forms.

Aluminum packaging material has excellent comprehensive protection performance

The water vapor transmission rate of aluminum material is very low, and it is completely opaque, which can effectively avoid the harmful effects of ultraviolet rays. Its gas-barrier, moisture-proof, light-shielding and aroma-retaining properties are much better than other types of packaging materials such as plastic and paper. Therefore, gold and aluminum packaging can maintain the quality of goods for a long time and have a long shelf life, which is especially important for food packaging.

Aluminum packaging material has a special metallic luster

It is also easy to print and decorate, which can make the product look luxurious and beautiful, beautiful and marketable. Additionally, aluminum foil is an ideal branding material.

Aluminum packaging materials are recyclable

In terms of environmental protection, it is an ideal green packaging material. As a packaging material, aluminum is generally made into aluminum plates, aluminum blocks, aluminum foils, and aluminized films. Aluminum plate is usually used as can-making material or lid-making material; aluminum block is used to make extruded and thinned and stretched cans; aluminum foil is generally used for moisture-proof inner packaging or to make composite materials and flexible packaging.

Aluminum cans

In beverage filling, cans for canned beverages are a good example. The advantages of aluminum materials in environmental protection and production cost reduction are gradually emerging. At present, the development of aluminum beverage cans has three characteristics: easy-open lids, special-shaped cans, and self-heating/self-cooling beverage cans. For a long time, although metal packaging such as aluminum beverage cans has been challenged by tinplate and PET materials, due to its light weight and recyclable advantages, it is still one of the main beverage packaging forms. And it is constantly developing and innovating.

The beverage packaging market is one of the big markets in the metal packaging market. In order to improve the brand effect, in addition to utilizing the silver-white characteristics of aluminum, the appearance of aluminum cans is becoming more and more important, so manufacturers of metal forming equipment are also discussing aluminum can forming and embossing technology. Because aluminum is easier to form and achieve desired shapes, researchers are exploring aluminum can roll forming, spin forming, and rheological forming techniques, which will first be used in beer cans in the near future.

The use of aluminum cans for beverages such as beer and soft drinks has increased the use of aluminum products, and other industries are currently considering aluminum cans.

Aluminum anti-theft bottle cap

At present, most of the domestic packaging of liquor, wine, medicinal wine and beverages is still dominated by glass bottles, of which about 50% of the wine bottle caps are made of aluminum anti-theft caps. By 2010, the amount of anti-theft covers will reach 15 billion, and about 60,000 tons of aluminum sheets and strips will be used. There are nearly 200 aluminum bottle cap production factories in my country, with an annual design capacity of about 9 billion pieces, of which 30 have introduced production lines with a production capacity of more than 5 billion pieces, which can produce nearly 100 kinds of bottle caps.

Aluminum bottle caps are mostly processed on production lines with a high degree of automation, so the strength, elongation and dimensional deviation of the material are very strict, otherwise cracks or creases will occur during deep drawing. In order to ensure the convenience of printing after the bottle cap is formed, the surface of the bottle cap material is required to be flat, without rolling marks, scratches and stains. Generally, the aluminum alloy materials used are 8001-HI4, 3003-H16, etc. The general thickness of the material used is 0.20~43.3mm, the allowable tolerance is ±0.1%, and the width is 449-796mm. The production of aluminum bottle caps can be produced by hot rolling billets or continuous casting and rolling billets respectively, which are formed by cold rolling. The production practice shows that the hot-rolled billet is better than the cast-rolled billet in the use effect of the anti-theft cover.
