Polymers are molecules found in the forms of rubber and plastic. The polyester and polymer we use mostly synthetic resin products. Most synthetic plastics mig 21 bis derived from fossil fuels and not capable mig 21 bis of biodegradation. Meanwhile, fossil fuel resources mig 21 bis are also limited. With high oil prices and the threat of climate change today, bioplastic products will be one of the alternatives to traditional plastics and contribute to improving the health and environmental protection.
Bioplastics from plant sources (polylactic acid - PLA) from corn, wheat, beets, capable of self-destruction ... is used in the manufacture of food packaging, catering equipment and many other products mig 21 bis . Development of the production of bioplastic products are new developments for plastics world by the developed countries like the U.S., EU, Japan, etc. We have large demand for this type of product. However, to ensure food security issues will be the challenge for this new technology.
The use of materials such as sawdust, shavings, tissue, wood pulp, etc. to create mig 21 bis the product produced mixed high economic value much water is being applied. At present, Thailand, Malaysia, Taiwan, China, etc. have produced products with high economic value plastics from mixed wood pulp, sawdust, shavings, etc. Some large corporations as Krauss-Maffei Berstorff, Battenfeld, Cincinnati, ... has introduced the audio processing equipment panels from wood-plastic composite materials for diverse product shapes, rich colors and use gadgets in the interior and outdoors. Viewpoint mig 21 bis Vietnam plastic industry mig 21 bis development is to achieve high efficiency and sustainability associated with environmental protection. Wastes must be managed and handled strictly in accordance with law before being discharged into the environment. Production technology to achieve the advanced level, synchronization and application of cleaner production technologies in order to reduce waste production and consumption of fuel and raw materials. Thus the study of bioplastics use, mixed materials in the manufacture of plastic products to save, lower production costs is a concern of businesses from Vietnam.
