How to improve the PET plastic bottles gases trap performance

PET plastic bottles have strong applicability, are widely used in the articles for daily use, cosmetic packaging and other fields. From the mould processing to the machinery and equipment has strong critical, introduction to easy, do the difficult. Because of light weight, save sex good, emphasizes the heat resistance, pressure, and other functions of the technical trend make PET plastic bottles today mainstream cosmetics packaging. Many need high temperature sterilization to fill drinks like flavored water, fruit juice, dairy products, such as sports drinks and the use of PET plastic bottles packaging, PET plastic bottles peremptory has become the Lord of the cosmetic container packaging materials. PET plastic bottles because of the low environmental pollution and energy wasting, in the rise of environmental protection consciousness gradually replace traditional packaging materials today. With its heat resistance, pressure, and other functions, close to replace the PVC bottles, aluminum cans, cans, glass bottles, etc. , become the growth potential of the packaging material. PET strength and elasticity significantly higher than the other materials, suitable for thin wall, light weight, high strength of cosmetic plastic container PET plastic bottles have been used for years in our country and the rapid development momentum. In recent years has become the main liquid and solid packaging container. Applications in the field of pharmaceutical packaging, under the same charge volume, PET plastic packaging bottles about 1/10 of the weight of glass bottle; Also the diameter of the bottles, PET plastic bottles of 1 is the capacity of the glass bottle. 5 times. Also can be made of PET raw material can be transparent or opaque brown bottles, color choice, elegant appearance. The improvement of the performance of the PET plastic bottles gases trap basically has the following four ways: by multi-layer co-extrusion technology processing, make have multilayer composite structure; Surface coating treatment; Add some gas capture agent; And the other has the blocking performance of material blending. Including multi-layer co-extrusion technology is successfully using the method, however, the improvement of the performance of the block is small, difficult to recycle at the same time, the cost is higher. Surface coating is used to improve the gas barrier performance of PET plastic bottles of a new technology, can be very thin gas barrier property of the membrane, can effectively prevent gas molecules through the wall of PET plastic bottles, at the same time can solve the problem of recycling. Currently used by some of the coating material has stood the test of practice, including diamond carbon membrane ( DLC) And oxidation silicon material is very popular in industry. Silicon oxide coating is used to improve the gas blocking performance of PET film is earlier than diamond carbon membrane. In the last century in the early 80 s, he began by physical vapor deposition and chemical vapor deposition method for silica coating. Silicon oxide film is brittle, however, for the sake of attaining lasting mechanical strength in the PET surface requires relatively complex processing. In recent years, the diamond carbon membrane ( The amorphous hydrocarbons) Some coating on the surface of PET products in the market has emerged, PET plastic bottles to improve the gas barrier performance greatly. ( Guangdong) Daily necessities co. , LTD. Is a focus on research and development production of PET plastic bottles. Mainly include wash protect plastic bottles, cosmetics bottles, food packaging bottle plastic bottles, beverage bottles, hotel products, such as new high transparent PET food grade raw material, the bottle is bright and clean bright, don't add any illegal material.
