Metal packaging development status and trend analysis

Metal packaging containers refer to thin-walled packaging containers made of thin metal sheets. It is widely used in food packaging, pharmaceutical packaging, daily necessities packaging, instrumentation packaging, industrial packaging, munitions packaging. Among them, the largest number of food packaging is used.

The metal packaging cans mainly include tinplate metal cans, two beverages, three beverage cans, milk powder cans, ordinary food cans, aerosol cans, crown caps, unscrewing covers, easy-to-open lids, miscellaneous cans, chemical cans, and 200 liters. Above steel drums and so on. Most of the materials used in metal packaging cans are steel and aluminum. Among them, steel is mainly low-carbon steel sheet, tinplate (commonly known as tin-plated steel sheet), Wuxi steel sheet (chrome-plated steel sheet), tin sheet (galvanized steel sheet), and coated steel sheet. Layer steel, covered iron; aluminum in aluminum, aluminum foil, aluminum film and so on.

The water vapor transmission rate of metal is very low, completely opaque, and can effectively avoid the harmful effects of ultraviolet rays. Its gas-barrier property, moisture-proof property, light-shielding property and fragrance-preserving property greatly exceed those of other types of packaging materials such as plastics, paper and the like. Therefore, metal packaging can maintain the quality of goods for a long time.

The demand for metal packaging cans has been great. In recent years, China's food and beverage industry has made considerable progress. According to statistics from the National Bureau of Statistics, from 2001 to 2013, the output of the beverage industry and the canned food industry in China achieved double growth. With excellent printing performance, noble metal texture, excellent flavor retention and other characteristics, metal packaging has an irreplaceable position in the food packaging industry, such as tea cans, moon cake boxes and milk powder cans and other metal packaging are owned in the domestic food packaging market The irreplaceable status is a market opportunity worthy of attention by related companies.

At present, for Japan and European countries, metal packaging accounts for about 14% of all kinds of packaging materials, second only to paper and plastic packaging, accounting for the third place; while in the United States, packaging metal consumption is more than plastic packaging, accounting for about second. China's metal materials account for about 8% of the total packaging materials, second only to plastic packaging materials.

The development trend of metal packaging in the future The rapid growth of food and fast-moving consumer goods is the first traction for the rapid development of this industry, and the upgrading trend of packaging products directly enhances the share of metal packaging products in various types of packaging products; in the future, metal packaging will pay more attention to food safety protection. , Pay more attention to thinning and reducing, pay more attention to recycling. About two-thirds of the steel cans in the UK are made from recycled materials. In some European countries, the recycling rate of metal cans exceeds 90%. Therefore, new requirements are put forward for the steel products for manufacturing metal packaging cans, such as containers and ordinary steel drums and other metal packaging containers, have greater strength and rigidity, and have the advantages of low cost, good processing performance, etc., and therefore require that the steel plate has a higher Strength and stiffness.

In addition, the cans of weakly acidic foods require steel plates with a certain degree of corrosion resistance. These foods are used in large quantities in the international market, such as meat, fish, poultry, dairy products, vegetables, carrots, peas, beets, potatoes, and others. Drinks, soups, etc. At present, chrome plated steel plates are mainly used in the production of beer bottle caps, beverages, and neutral food cans, and there are few food cans. This requires the steel plate to have greater corrosion resistance.

Faced with the large number of small and medium-sized packaging companies, redundant construction, and the overcapacity of low-end products, China's metal packaging industry has accelerated industrial adjustment and the trend of industry consolidation has become increasingly clear. In particular, advantageous enterprises rely on their leading technological level, advanced management experience and strong financial strength to continue to grow bigger and stronger, promote orderly competition in the industry, promote the survival of the fittest in the industry, and thus improve the overall competitiveness of the industry.

At present, the leading enterprises in the metal packaging industry have begun to shift to large-scale, group-based, and professional development. Large-scale metal packaging leading companies often have stronger anti-risk capabilities, stronger research and development capabilities and higher technical standards. With the gradual emergence of large-scale metal packaging groups, the industry's management level and barriers to entry are bound to further increase, thereby narrowing the gap with the international advanced level, and increasing the brand value of leading enterprises, forming technological advantages and economies of scale, and the SMEs in the industry Have a good demonstration role
