New progress in foreign composite plastic packaging technology
foreign countries have also made rapid progress in the development of composite plastic packaging, such as CT materials. The Japanese computer system has successfully prepared a special plastic for food packaging containers - CT through the controller. This kind of plastic is a new composite material made by blending talc powder from Liaoning Province, China, with half of large paper added to polypropylene plastic. CT has the characteristics of high temperature resistance, and its function is similar to that of foamed plastic products, but its volume is only one quarter of that of the latter, which can alleviate "white pollution"
rape plastic packaging materials: Although new materials have been innovatively used in various fields, recently, American researchers have developed a kind of rape plastic packaging materials that is easy to decompose. It extracts three genes that can produce plastics from the cells that make biopolymers, and then transfers them to rape plants. After a period of time, it produces a plastic neopor? Foam contains graphite particle polymer liquid, and then after refining, a kind of rape plastic can be obtained. The packaging plastic or food fast food packaging material processed from this kind of rape plastic can degrade by itself
wheat plastic packaging materials: This is the use of wheat flour mixed with glycerol, glycol, silicone oil and other dry, and then after adding 150kg pressure per square meter hot pressing into a translucent thermoplastic film, which can be decomposed by microorganisms
wood flour plastic packaging material: not long ago, Japanese scientists and technicians developed a wood flour plastic packaging material from pine, which is prepared from wood flour and then reacts with isocyanate to produce polyurethane. This kind of wood flour plastic has strong heat resistance and can be used to make temperature resistant packaging bags, etc. This packaging material can be biodegradable
