Plastic Packaging Industry Development Trend Of Green
Enter the new century, the world's major economic restructuring and continue to deepen the change and sustainable development strategies is the world's industry, changes in the overall context, but also plastic packaging industry, changes in the environment background. As the environmental impact of the wave, consumer packaged goods raised higher and higher requirements. Green packaging is the need for international environmental protection trend, but also represent the development trend of countries in the packaging industry is to enhance the competitiveness of product markets, to avoid an important part of new trade barriers. Correspondingly, the green plastic packaging has become an important trend.
The development of green packaging materials recyclable
Packaging Waste regulations vary, but there is a common principle: to encourage less use of raw materials. In the packaging design should make full use of the same material, detachable material can co-exist, and tend to use simple, easily recycled materials. To meet the packaging functions under the premise of minimizing the amount of garbage generated, thus rendering lightweight packaging film trends.
Plastic Stabilization Technology
Plastic steady technological development is the key to a new antioxidant, UV stabilizer and free radical scavenger preparation and application of research and development. Japanese chemical re-filling plastic containers, food trays or turnover boxes can be used to stabilize plastics technology, manufacturing high quality plastic products, in order to enhance its reuse or recycling value.
Biodegradable Plastics Technology
Biodegradable plastics are generally divided into biodegradable plastics, optical and bio-degradable plastics / light degradable plastics. Variety of domestic R & D has been covered by photodegradation, optical bio-degradable, bio-degradation of optical oxygen, high-starch-based bio-degradable, high-calcium carbonate-filled light-oxidative degradation, all bio-degradable and other major categories. Biodegradable plastics in packaging applications, has spread in common packaging film, shrink film, shopping bags, garbage bags and so on, for improving the quality of the environment has played an active role. From protecting the ecological balance starting to study the complete bio-degradable plastics is imminent, especially the consumption of powder or inorganic mineral filled, high-quality, low-cost full-biodegradable plastics are biodegradable plastics is currently an important research topic.
Incineration heat recovery or re-use of steel-making furnaces with the development of plastic waste
Burning of plastic waste heat recovery recycling as a major means of plastic waste management is the most realistic option. Research and development of plastic waste in the future should be to provide thermal energy related equipment, designed to use easier, live longer and lower prices of equipment, in order to speed up the recovery of China's burning heat and the use of steel-making furnaces re-use plastic waste research and development.
Edible Films
Edible packaging films based on a natural edible substances (such as polysaccharides, proteins, etc.) as raw materials, through the interaction between different molecules formed with a porous network structure of the film. Such as chitosan edible packaging films, packaging films of corn protein, modified cellulose membrane composite edible packaging edible packaging film. Edible films can be used in a variety of instant foods inner packaging in the food industry should have a huge market.
Water-soluble plastic packaging film
Water-soluble plastic packaging film as a novel green packaging materials, in Europe, America, Japan and other countries has been widely used in packaging of various products, such as pesticides, fertilizers, pigments, dyes, detergents, water treatment agent, mineral additives, cleaning agent, concrete additives, photographic chemicals and chemical reagents and other horticultural care.
Development of circular economy development of corresponding policies plastic
At present, sub-put solid plastic waste facility in Shanghai has emerged, but there is still a lot of people put at random. A considerable number of regions, departments and enterprises to show care for immediate benefits of short-term behavior.
Environmentally friendly food packaging plastic CT
CT is not only temperature, as well as one of the most prominent advantage is that it functions and commonly known as "foam-bubble plastic" in plastic similar to PSP, and its size is equivalent to the latter's 1 / 4. So that recycling avoids bulky generated a lot of trouble, and to eliminate the negative impact on the environment creates the most favorable conditions.
New type of high barrier plastic packaging materials
The use of high-strength high barrier plastics can not only enhance the protection of food, but also in the same amount of food packaging can reduce the amount of plastic, and even can be reused. China is now commonly used in high-barrier materials are aluminum foil, nylon, polyester, polyvinylidene chloride and so on. Along with the protection requirements of food increased, and better barrier ethylene vinyl alcohol copolymer, polyvinyl alcohol, also to begin.
