Aluminum beverage cans and innovative new bottle shape attract sb.'s attention

At present, the development of aluminum beverage cans has three major characteristics, namely easy to pull lid, special cans, self-heating / self-cooling beverage cans. Although metal cans such as aluminum cans have long been challenged by tinplates and PET materials, they are still one of the major beverage packaging forms due to their light weight and recyclability. They have not only been steadily developed, But also constantly developing and innovating. Recently, coins packaging company successfully developed the "EPOL" (easy to open lid). This lid is heat-sealed with a polymer-coated steel ring and a corrosion-resistant aluminum foil for use with existing filling equipment. The foil lid opens securely and is more suitable for the elderly and children. Demand for aluminum cans for beverages in Japan has been declining in recent years due to the competition from PET bottles. However, with the development of new aluminum cans, the demand for aluminum cans has started to rise again. Currently, companies such as Wujin Stamping Industry, Yamato Can Manufacturing Co., Ltd. and Mitsubishi Materials have entered the aluminum can production area and the aluminum can lid developed by the Chaizaki Manufacturing Plant has been put on the market at the same time. It is reported that Daiwa Can, Wu-stamping industry two companies started in 1997 aluminum bottle research and development. They have successively developed aluminum can beverage containers that preserve the excellent properties of the original aluminum cans and their ease of recycling and resealing.

The newly developed aluminum bottle has the following characteristics: (1) compared with the original aluminum cans, beautiful and stylish appearance, and can be re-sealed, easy to carry, easy to recycle; (2) compared with PET bottles, Sex greatly improved, while the tank weight reduced by 30%; (3) the preservation of the installed drinks excellent performance, extended shelf life. Daiwa Cannery and Wuhu stamping aluminum container industry somewhat different structure. The product of Yamato was 28 mm in diameter (the mouth of the 2-piece can was shaped as an opening for forming this caliber); the lid, the can and the bottom lid were all made of aluminum; the weight of the aluminum can As an example), only 67% of the PET bottle; the inside of the tank and bottom cover is covered with a polyester film and the inside of the top cover is covered with a low-density polyethylene film. Wuhu stamping industry and Yamato cans aluminum bottles of different points: caliber 38mm; tank design smooth, easy to print. Mitsubishi Materials from the Wu-stamping industry to introduce this technology, the Okayama factory has transformed the third production line into a dedicated aluminum bottle production line into the field. According to the survey by the Aluminum Can Recycling Association in Japan, sales of aluminum cans alone reached 1.5 billion cans in 2002, 2.5 times more than in the previous year, as the four companies entered the production of aluminum cans. In 2003, on the basis of this Increase about 20%. The beverage packaging market is one of the larger markets for metal packaging. In addition to the silver-white nature of aluminum, the appearance of aluminum cans is also becoming more important for improving the brand's effect, so manufacturers of metal forming equipment are also discussing aluminum can forming and embossing. As aluminum is easier to shape and reach the desired shape, researchers are exploring aluminum can roll expansion forming, spinning forming and rheo-forming techniques that will be first used in beer cans in the near future.

Experts believe that the new market share of aluminum cans will make new progress with the so-called "active packaging" (in English, "activepackaSing"). At present, self-heating coffee pots have been sold in some supermarkets. Researchers are still developing self-cooling beverage cans for consumers to drink anytime, anywhere. Due to the application of new technology for the development of aluminum cans, the demand for aluminum cans is likely to expand further in the future. The new aluminum cans packaging will be more attractive internationally.
