For a long time, although metal beverage cans have always been challenged by tin-plated metal cans and PET beverage bottles, due to their light weight and recyclable advantages, they have been steadily developing, and they have continued to innovate in product development.
Corus Packaging Corp. recently introduced the "EPOL" (easy opening cover). This can lid is coated with a polymer-coated steel ring and heat-resistant aluminum foil, which can be safely opened and is more suitable for the elderly and children.
In recent years, in the Japanese packaging market, due to the increase in PET bottles, the demand for aluminum cans for beverages has gradually decreased, but with the development of new aluminum cans, the demand for aluminum cans has started to rise again.
At present, companies such as Takei Stamping Industry, Daiwa Manufacturing, and Mitsubishi Materials have entered the production of aluminum cans, and aluminum can lids developed by the Caisaki Manufacturing Plant have also been put on the market.
It is reported that the two major companies, Yamato Can Making and Takeuchi Stamping Industry, began research and development of aluminum bottles and cans in the past few years. Aluminium bottled beverage containers have been developed successively with the function of maintaining the quality of contents and easy recovery and resealing. The newly developed aluminum cans have the following features:
First, compared with the original aluminum can, the appearance is beautiful and can be re-sealed, easy to carry, easy to recycle;
Second, compared with PET bottles, the light protection and barrier properties are greatly improved, while the can weight is reduced by 30%;
The third is the excellent preservation performance of the loaded beverages and the extended shelf life.
There are also certain differences in the structure of aluminum bottles and cans between Daiwa Canning Company and Takeuchi Stamping Industry. The diameter of the Yamato cans is 28mm. To shape the caliber, the bottom of the jar is formed as a mouth, and the lid, the tank, and the bottom cap are all made of aluminum. The weight of the aluminum bottle (in the case of a 500 ml bottle) is only 67% of the PET bottle. The inside of the tank and the bottom cover were covered with a polyester film, and the inside of the top cover was covered with a low density polyethylene. The difference between the Wuhe Stamping Industrial Company and the Daiwa Glass Can Company's aluminum cans is that the caliber is 38mm, and the design of the tank body is smooth and easy to print. Mitsubishi Materials Corporation, after introducing this technology from Takei Stamping Industrial Co., Ltd., has transformed the third production line of the Okayama Plant into a special production line for aluminum bottles and canals.
According to a survey conducted by the Japan Aluminum Can Recycling Association, as the four companies entered the development and production of aluminum bottles and cans, the sales volume of aluminum cans reached 1.5 billion in 2002 alone, which is 2.5 times that of the previous year. Based on this in 2003, Another 20% increase. The packaging material market is one of the largest markets for metallic materials.
In order to improve the brand effect, in addition to utilizing the silvery white nature of aluminum, the appearance of aluminum cans is also increasingly important, so manufacturers of metal forming equipment are also studying aluminum can forming and embossing technology. Because aluminum is easy to form and achieve the desired shape, researchers are exploring techniques such as aluminum can roll reel forming, pressure forming, and rheology, which will be used in beer cans in the near future.
