PET beer bottle molding process

PET beer bottle molding process is also developed on the basis of cold filling PET bottle technology. However, compared with the above two types of PET bottles, since the beer bottles require a very low oxygen permeability and require a certain degree of protection from light, the structure and composition requirements of the PET bottles have changed (this is also the passage of PET bottles. The direct reason why it has been gradually used in the beer industry for so many years.) One of the more popular PET beer bottle processing technologies is the coating method of the Sidel company in France (that is, the inner surface of the bottle is coated with a layer of SiOx film or carbon film), that is, the production of cold-filled PET bottles. Mr. Crafts produces ordinary PET bottles and then carries out inner-layer coating processing. The other type is multi-layer composite PET bottles developed by companies such as the United States and Japan. The difference between the adding process and the cold-filled PET bottles lies in Tube blank processing is a three-layer composite tube formed by co-injection molding.
