TH105141B - Method of doing shoulder / tip with barrier film mat. - Google Patents

Abstract

Methods are combined with automatic techniques for making and inserting a film layer that blocks the Flexible to the shoulder / end of tube product packaging. The shoulder / end was made and positioned with an opening in the shoulder facing the film layer. The film was fed to the resulting station. The opening at the end, the cutter head cuts the film to fit the shoulder / tip, and inserts the film layer into the shoulder / end of the film can be thermally bonded to the shoulder / tip at this station or the sealing station at Together After the shoulder / tip exits the station, which makes it into shape, and inserts a layer of film into the shoulder / tip, there It can be a measuring station to determine if the film layers are properly positioned in the shoulder / end. There is also a measuring station after the adjacent sealing stations. Shoulder / end with sealed film layer From this point, it was sent to the tube making section. The film layer will have a polymer layer and a barrier layer composed of ethylene vinyl alcohol copolymer, polyethylene terephthalate polymer, polyethylene. Ethylene Naphthalate Polymer, and Acrylonitrile Methyl-acrylate copolymer, tube packaging is manufactured using These shoulders / ends It is very useful for products containing scent, such as toothpaste.
