Development Of The Bottle Material
Sep 03, 2018

The process of manufacturing barrier plastic bottles using coating technology has been declining, with the German Krones AG and Tetra Pak, Illinois State, which have begun to cut production scale. Krones Company and Coca-Cola Company jointly developed the Bestpet technology, coated with silicon oxide coating on the outer surface of the bottle.

A spokeswoman for the company said the technology was outdated because of the high cost and inadequate barrier to oxygen, and Tetra Pak has terminated the research work on the Glaskin Silica plasma coating system applied to the inner wall of pet bottles. In addition, the Italian SIPA company designed for Pen bottle developed a new barrier dip coating material, its commodity name is smart Coat, the process is: blow molding to get the bottle after the dip coating process, and then immediately put into the infrared oven so that the bottle drying quickly, and then after the second coating, While the bottle is cured under ultraviolet radiation, a standard dip coating device can handle about 12,000 plastic bottles per hour.

One of the goals of this pet bottle is filling carbonated drinks, according to the company, 0.5 liters of capacity, a single-purpose dipped pet bottle, the shelf life of packaged goods can be up to a year, while the product without dipping pet bottles shelf life of only 7 weeks. The UK Innovative Plastics technology company (AFT) has developed a patented water-based flow coating process that allows the outer surface of a special barrier thermoplastic resin preform to be coated, and after the preform has been coated, the resin is cured and the preform can be blown two times on standard processing equipment. Apt claims that the coating process has increased the barrier performance of the co by 3-4 Times compared to the uncoated pet bottle, and that husky is negotiating with apt to transfer the technology to obtain the operating license to manufacture the coating equipment, which is designed to process 30,000 preforms per hour, Director of APT company Robert. Lee said.

The technology has been purchased by a leading company in the production of beverages and is used in the processing of non-alcoholic beverage packaging bottles. The Plastics Processing Research Institute (IKV) of the University of Aachen, Germany, has transferred its developed plastic bottle wall Plasma coating technology-PECVD to Sidel, IKV has also developed a plastic bottle coating technology using a 20-150nm barrier coating, similar to the inner wall coating process,

Can improve the pet bottle 4 times times the Co barrier performance, its technical production system device processing period of 15 seconds, production regardless of 10,000 bottles/dismissed, the researchers set the development goal is: the processing cycle cycle reduced within 10 seconds, the use of more powerful vacuum pump, and other improved detection device.
