Cans (metal beverage containers)
At 1959, Ernie. Aimar Klinan Fraise of DRT Company in Dayton, Ohio, invented the pop-top can, that is, the material of the can cover itself was processed into rivets, and then the jacket was riveted with a pull ring, and then the corresponding notches were matched to form a complete can cover. This genius's invention made a historic breakthrough after the long development of metal containers for 50 years. At the same time, it also laid a solid foundation for the development of canned food and beverage industry. Pop cans originated in the United States and prevailed in the United States.
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%.
