The Development Of High Resistance Diaphragm

The development history of high barrier industries has been over 20 years. Since the mid-1970s, many polymer groups have started to market barrier film materials for packaging. At that time, the processing method for this material was to use polyolefin materials as adhesives to composite similar polymer films into multi-layer structured films.
At the beginning of developing the high barrier packaging industry, consumer demands were the primary factor in market development, but cost issues were also an important factor in the development of this new material. Developers believe that keeping food in its fresh state as much as possible when it reaches consumers is the primary driving force for developing new materials. The second driving force refers to the optimization operation, that is, achieving the lowest cost of thin film materials. In other words, products should be sold at reasonable and accurate prices. If it is only for packaging ordinary potato chips and other products, there is no need to design and manufacture a high-end film. Developers generally believe that economics lies behind development, while creativity lies behind the market. The high barrier lightweight flexible packaging market is a good example. To achieve the goal of replacing metal cans, glass bottles, or other hard packaging with polymer packaging, high barrier materials and co extrusion technology must be used.
