The state of corporate environmental awareness training directly affects the pallet business

 Now, with the continuous improvement of consumer attitudes, people's growing awareness of environmental protection. In the process of consumption of the product is non-toxic, green have become increasingly demanding.
   China is the world rapid development of antibacterial home country since 2003 after the SARS incident, the standardization of antimicrobial appliances are on the agenda. After various efforts society, from the post-2008 National Technology Quality Supervision and Quarantine promulgated successively appliances antibacterial, sterilization of a series of standards, these standards for regulating and promoting the development of antibacterial function appliances played a landmark role. Antibacterial appliances without the use of antibacterial plastic. According to the research report predicts that by 2015, the global antibacterial plastics for industrial applications market will reach 1.4 billion pounds, the value used in consumer powered palle ttruck was 10.3 billion pounds, up to 20% of the global plastics will have antibacterial function. It is reported that antibacterial plastic itself has antibacterial properties in a certain period of time to kill or inhibit bacterial contamination on plastic.
And with conventional chemical and physical methods, antibacterial plastic sterilization time is relatively long. In recent years, anti-bacterial plastic as these unique advantages have been widely used in home appliances, packaging and other areas. Among them, the home appliance industry is the most widely used antibacterial materials, the most mature areas. Because the plastic with light, does not rust, good insulation, Hand pallet trucks., in the production of appliances to be used in many areas of plastic, while the appliances with people's daily life very closely, making the current home of microbial contamination affecting people's health has become One important factor, therefore, the use of antimicrobial plastic instead of ordinary plastic has become a household appliance industry trends.
Trade as a result of a plasticizer for plastic pallet industry inadequate investment in technology, new product development directly affects the slow, imported high-grade plasticizer product prices are still high and eat, but large plastic tray products companies in order not to affect the plastic tray quality, are also generally higher prices abroad choose plastic plasticizer, plasticizer 2010, imports amounted to 270,000 tons. Plastic forklift pallet while the domestic low-level, non-environmentally friendly plasticizer has excess capacity, industry operating rates insufficient vicious market competition, causing the entire plastics industry unstable.
The total amount of environmentally friendly plastic products, plasticizers, fewer species, the proportion is low. At present China's market demand plasticizer tonnage of 220 tons, as early as the 1980s, the EU has proven carcinogenic to animals DOP Box Others toxicity. In recent years, many of our products are exported by the United States and other countries seized, returns, causing huge economic losses.
This country has been customized according to international standards, seize quality, restrict or limit use of part of environmentally friendly plasticizer products. As the market for green plastic plasticizer rapid increase in demand, and to increase investment in science and technology, developing non-toxic green plastic pallet industry plasticizer become key to sustainable development.
The face of an increasingly hot topic environmental, anti-bacterial plastics and environmentally friendly plasticizer in the future will be the development of Henan plastic tray must go through
