(Summary description)The barrier coating can be used on the inside and outside of the package, but many factors need to be considered in the specific choice of which method, plasma treatment technology is an effective method in this application. The permeability of the gas in different parts of the PET container is also different due to the biaxial orientation of the molecules inside the plastic. The outer coating is easy to cause mechanical damage. But in order to improve the scratch resistance, secondary coating process can be used for treatment. The advantage of inner coating is that it can prevent the change of packaging bottle material from having an impact on the food performance, but the inner layer is in direct contact with the food, so the interaction between the two must be considered. The coating on the inside of the filling bottle is subject to intense cleaning and may fall off during cleaning. In order to prevent fracturing of the bottle body, the outer space of the bottle body needs to be vacuumed when the vacuum coating system works. In addition to improving the mechanical and optical properties of the polymer, it is necessary to ensure that the polymer has good bonding properties, so plasma surface treatment is needed. The substrate surface condition before coating treatment is an important factor to determine the performance of vacuum deposition barrier coating. Many common polymers have low surface energy, so it is difficult to get a good barrier layer by coating treatment. The surface of the material can be treated by plasma treatment with high-energy ions, free radicals, electrons and neutral particles, which can make the surface modified molecules reach a certain depth. In the process of plasma surface treatment modification, not only dirt (such as organic matter) can be removed, but also some functional polar groups can be generated, which promote the bonding and generate the compensation effect through crosslinking. Corona discharge is often used in the process of winding coating, which is efficient and economical for many polymers. According to the practical application, the newly developed surface treatment technology can be used to ionize the mixed gas in the rf plant, combine with the DC magnetron sputtering technology, and use the plasma treatment technology to oxidize, nitride, ammoniate or hydrolyze the surface, so as to enhance the surface energy of the material and improve its binding performance. In addition, the surface morphology of selected materials also has a great influence on the performance of the barrier layer. For example, a smooth, flat base is easier to coat with high-quality septal faults.
