Bottle development of plastic bottles

The process of manufacturing barrier plastic bottles using coating technology has shown a downward trend, and Krones AG in Germany and Tetra Pak in the United States (Tetra Pak, Illinois) have begun to reduce production scale. Krones, together with The Coca-Cola Company, developed BestPET technology, which applies a silicon oxide-containing coating to the outer surface of the bottle. A company spokesperson claims that the technology is outdated due to high costs and inadequate oxygen barrier properties, and Tetra Pak has terminated research into the Glaskin silica plasma coating system applied to the inner wall of PET bottles.
In addition, Italian SIPA company for PEN bottle to develop a new type of barrier dipping material, its trade name is Smart Coat, its process flow is: blow molding processing to obtain the bottle, after the dipping process, and then immediately put into the infrared oven to quickly dry the bottle, and then after the second coating, the bottle is cured under ultraviolet radiation, a standard dipping device can process about 12,000 plastic bottles per hour. According to the company, 0.5-liter capacity, single-purpose dipped PET bottles can have a shelf life of up to one year, compared to just 7 weeks for goods without dipping PET bottles.
Innovative Plastics Technologies (AFT) has developed a patented water-based flow coating process that coats the outer surface of a special barrier thermoplastic resin preform that cures and can be second-stretched and blown on standard processing equipment. APT claims that the CO barrier performance of this coating process is 3-4 times higher than that of uncoated PET bottles, and Husky is negotiating with APT to transfer the technology to obtain a license to manufacture this coating equipment, which is designed to process 30,000 preforms per hour, said APT director Robert. Lee said. This technology has been purchased by a leading beverage manufacturer and used to process non-alcoholic beverage bottles.
The Institute for Plastics Processing (IKV) at the University of Aachen in Germany has transferred its development of plasma coating technology on the inner wall of plastic bottles - PECVD, to Sidel Corporation, IKOV has also developed a plastic bottle outer wall coating technology, using 20-150nm barrier coating, similar to the inner wall coating process, can improve the CO barrier performance of PET bottles by 4 times, the processing cycle of its technical production system device is 15 seconds, and the researchers set the development goal of reducing the processing cycle to less than 10 seconds. Use more powerful vacuum pumps, as well as other improved inspection devices.
