Plastic raw material development process

The coating technology manufacturing process has been declining trend, barrier property plastic for Germany Krones AG, tetra companies in the United States ( Tetra Pak, Illinois) Began to cut production. Krones company jointly developed with Coca-Cola company BestPET technology, outside the bottle surface coated with silicon oxide coating. A company spokesman says, because the cost is too high, the oxygen barrier performance is inadequate, the technology is obsolete, tetra pak company has terminated the application on the inner wall of the PET bottle Glaskin silica plasma coating system research work. In addition, the Italian SIPA company designed for PEN bottle has developed a new type of barrier property of dip coating material, its goods is called Smart Coat, its technological process is: when we get bottle blow molding processing by dip coating process, and then into the infrared drying oven inside the bottle drying quickly, and immediately after the second coating, ran to the bottle under ultraviolet (uv) radiation curing, a standard dip coating device can handle about 12000 plastic bottles every hour. This is one of the goals of the application of PET bottle filling carbonated drinks, according to the company, 0. 5 litre capacity, single purpose after dip coating of PET bottle, the shelf life of packaged goods can be as long as a year, and without dip coated PET bottles goods shelf life only seven weeks. The British innovation plastic technology co. , LTD. ( 尾) Developed a flow of water-based coating process, the patentability of a special barrier property of thermoplastic resin system bottle preform surface coating processing, mold after coating process, resin curing, can be in the standard bottle preform secondary stretch blow molding processing equipment. APT company claims that use this coating process compared with the PET bottle without coating, blocking performance improvement of CO 3 - 4 times, husky company is technology transfer matters, consultation with the APT company for manufacturing the business license of the coating equipment, the design of the equipment production capacity is 30000 bottles per hour processing billet, APT company director Robert. Li said. The technology has been a beverage production enterprises to purchase, is applied to the processing and soft drink bottles.
