Canned material

There are two kinds of materials for making cans: aluminum and tinplate. 1998 The consumption of aluminum metal materials for packaging containers in the United States reached 1.992 million tons, an increase of 2.24% over 1.997 tons, making it the second largest consumer market, accounting for 2 1.6% of the annual aluminum consumption. In the United States, aluminum plate has been used as the material of cans, and about 40% of aluminum plate is used in the production of cans every year. About 65,438+04% aluminum metal materials in Europe are used in beverage production. Due to the high recycling value of aluminum metal, a large number of aluminum materials have turned to environmental protection. 63% of the cans produced in 1999 were made of aluminum, an increase of 2% compared with 1998. Compared with 1999, it increased by 9% in 2000, 6.6% in Britain and 6% in 2000. Finland, Switzerland, Greece, Italy, Poland and other canned markets began to adopt 100% aluminum, Germany 10%, France, Belgium and Poland. Because the cost of steel cans is about seven thousandths lower than that of aluminum cans, steel cans occupy a dominant position in the South American beverage packaging market, but with the improvement of environmental awareness. Moreover, considering the recycling of resources, aluminum is gradually replacing steel as packaging material. The adoption rate in Brazil is 65%, which will increase by 10% in two years. In terms of spray cans, steel used to dominate, but since 2000, many products have turned to aluminum, with a growth rate of 2% ~ 3%. With the application of stretching technology in the production of spray cans, aluminum spray cans will gradually occupy the market. Recovery of aluminum

The strong rival of aluminum in the packaging industry comes from PET material, which can be made into strange appearance by injection mold, while aluminum material is relatively difficult, but the prices of the two materials are quite different. PET is affected by oil price, and aluminum can be recycled by itself, which reduces the material cost and is re-valued by environmental protection organizations. Europe, America and some areas with active consumption of cans are constantly improving the recovery rate of aluminum cans and aluminum packaging materials. Countries that start early in recycling no longer argue about the recycling value of waste aluminum cans, but become daily work, while countries that start late are making great efforts to do it. The United States is the country that started this project earlier and has the highest recovery rate. Germany and the Netherlands play a leading role in Europe. Mexico advocates a recovery rate of 100%. In recent years, the recovery rate of waste cans in the United States is 100%

Environmentalists believe that aluminum cans are more environmentally friendly than other packaging containers. As far as their containers are concerned, repeated recycling reduces environmental pollution. As far as the materials used are concerned, the repeated use of aluminum can effectively save resources and maintain the global environment, while other packaging containers, such as plastics and PET materials, are all derived from petroleum, and the uninterrupted exploitation of petroleum will cause the exhaustion of resources. 1999 the recycling rate of discarded packaging containers in some countries is%

Note: ① The overall recovery rate of European steel packaging containers is 47%.

② The recovery rate of Japanese 1998 aluminum cans was 74.4%, of which 79% was reused to manufacture aluminum cans.

5. Continuously improve technology and reorganize assets.

In order to maintain the leading position of pop cans in beverage and beer packaging, the pop can industry is constantly undergoing technological transformation, and reducing costs and improving appearance have become the main theme. In order to greatly reduce the cost, Crown Group of the United States has developed an aluminum easy-to-open cover called "Super Cover". And put it on the market. It is said that this product can save 10% of materials compared with the original product, and the annual production capacity of this product is1800 million. The production plan is being accelerated to meet the demand and achieve an annual production capacity of 7 billion vehicles. In addition, the company has also developed self-cooling tanks of environmental protection refrigeration materials, with the first batch of 35 million. This self-cooling tank can cool the beverage 15℃ in less than three minutes after the pull ring is opened. In terms of reducing material thickness, North America switched from 204-gauge tank mouth to 202-gauge tank mouth, and the thickness of aluminum and steel decreased to 0.259mm and 0.22 mm For the control of ink quantity in metal color printing, the density method was used to eliminate the difference of different observers' feelings and understanding of the same pattern color and the influence of sufficient light on color judgment, so that the ink content in color was effectively controlled in terms of relief and process cost of different shapes. The achievements and turning point of metal color printing technology can be seen by picking up the cans with realistic figures and animal patterns that won the crown of world metal packaging containers in 200 1 year.

Some large international canning industry groups, as well as the mold manufacturers of canning equipment, are reorganizing their assets to control costs more effectively. The domestic can-making industry is still full of difficulties.

The domestic canning industry started in the early 1980s. Although it has a history of only 20 years, it has experienced three crises. For the first time, under the policy background of 1988, domestic public opinion circles had a heated debate on whether the production and consumption of cans conformed to the national conditions. At that time, cans were regarded as high consumption, worshipping foreign things and obsessing foreign things. At the same time, the state has raised the import tariff of raw materials from 20% to 40%, and the production enterprises are facing the test of life and death. The second crisis occurred in June, 1989. Due to well-known reasons, the national beverage market has plummeted, and the can industry is in trouble. The third time was the "exchange rate storm". After 1990s, the domestic can-making industry developed rapidly. Expand the original tank factory and increase the number of new tanks, reaching an annual output of 654.38+000 billion pieces. However, due to the failure to effectively break through the demand, overproduction led to the fourth crisis. In recent years, the domestic demand for cans has always remained between 6 billion and 7 billion, so the domestic cans factory has still not been able to get rid of the predicament. On the one hand, influenced by people's traditional consumption habits and consumption levels, glass bottles still dominate beer packaging. On the other hand, cans are no longer regarded as high consumer goods or fashion consumption, but because of their economic level, it is difficult to become mass consumption, thus replacing glass bottles. For example, German cans have gradually replaced beer glass bottles. Furthermore, because most of the tank industry is in trouble and influenced by related industries, it is difficult for tank factories to invest a large sum of money in large-scale technical transformation to reduce costs, thereby reducing the overall price and promoting consumption. With the intensification of market competition, the law of survival of the fittest will be manifested in the domestic can-making industry, and the domestic can-making industry will refer to the development path of foreign can-making industry to carry out technological transformation and asset restructuring. According to experts' prediction, by 2005, China will consume 900,000 tons of aluminum for packaging, accounting for 14.3% of the total consumption of aluminum. With the continuous growth of the national economy, the improvement of people's living standards and the emphasis on environmental protection, domestic cans will usher in a brilliant day after the fourth crisis. In a word, the development of canned food industry is closely related to the level of economic development in this area. Economic development promotes environmental awareness and recycling of effective resources, thus forming a virtuous circle. Throw away the "cans" after drinking? The beverage cans that we often throw away are now collectibles. With the gradual enrichment of the materials and varieties of cans, the unique and limited edition cans have been worth more than 10,000 yuan, and the cans with a few yuan have also turned into "money-shaking cans".

The return on investment is as high as dozens of times.

Unique can management counter. This is a special counter, which deals in a kind of "new favorite of collection"-cans. Among them, the empty coke can "Star Wars Trilogy Movie Memorial Tank: Star Wars Darth Vader Special Edition" is priced in 580 yuan; A set of 20 12 British Coca-Cola (***3 cans) for London Olympic Games is sold in 600 yuan; At present, the most expensive can is the Coca-Cola space can specially designed for astronauts to land on the moon. 1985 is made in the United States, with a price tag of 30,000 yuan. Ma, a long-term collector of beverage brands and commemorative cans, told reporters that although the initial investment of commemorative cans is only a few yuan or dozens of yuan, its return on investment is as high as dozens of times. For example, the Coca-Cola "Cecilia Cheung" cans released on 200 1 Nanjing, because no one noticed the collection, most of the products were consumed by the market, and the remaining quantity was very small. 2 1 century, the price of a single can has risen to 5000 yuan to 6000 yuan; Coca-Cola cans issued by Barcelona Olympic Games 1992 also rose to 2,000 to 3,000 yuan on 20 10.

Appearance determines value.

From the collection trend, the mainstream of cans is still aluminum, tinplate and other metal products. However, scarcity is precious, and some collectors mainly collect cans with different shapes and different opening methods. The most important thing to pay attention to in the collection of cans is the appearance. There must be no scratches, dents and scratches. Tinplate cans must not have any rust spots, and they cannot be easily collected unless they have been in circulation for a long time. In addition, the value of some special varieties has reached hundreds or even thousands of yuan. Domestically, the Coca-Cola cans produced in China in the early days and some domestic brands of beverage cans have become treasures sought after by collectors at home and abroad because of their small survival.
