After several years of development and application found that the processing of plastic materials than ordinary plastic products difficult, demanding. At present, most of the domestic technology from the foreign technical information digestion, absorption, although achieved some success, but there are many industrial applications to do. And some manufacturers only to see the prospects of plastic and wood, while ignoring the other problems, processing equipment, technology, etc. are not up to the requirements of the product grade do not go; a small number of enterprises to produce molded wood-plastic packaging materials , Due to the small proportion of wood filling, high cost, lack of market competitiveness.
With the increasing emphasis on the recycling of waste plastics and the growing lack of timber resources, with wood flour or other natural plant fiber to fill the plastic renewable materials, made of special equipment made of wood materials and products, because both Plastic and wood dual characteristics, in recent years cut a striking figure, and gradually become the world's attention and development of hot spots. But after several years of development, plastic wood materials in the domestic production and application situation is not optimistic, on the one hand the results of industrial difficulties, and on the other hand sales of plastic materials production enterprises are also poor. Plastic wood plastic wood material this potential environmental protection why the new material why the applause of the situation? Plastic wood materials are currently the most widely used in the international product is the tray, Europe and North America, plastic wood tray has accounted for nearly half of the market share.
China's current annual demand for pallets of about 100 million to 2015 will grow to 200 million, according to the time will be 30% of the plastic wood tray market share, only one can consume 1 million tons of waste plastics per year. Plastic wood in the United States, plastic wood materials market, the average annual growth rate of more than 13%, only plastic sheet market has more than 600 million US dollars.
At present, there is no uniform standard of plastic wood in the country, the standard of plastic wood pallets is only the reference to the wooden pallets standard revision, not complete. In this case, some manufacturers blindly exaggerated propaganda, damage the entire industry. The relevant state departments and industry organizations should formulate relevant industry standards as soon as possible and establish industry standards to ensure the healthy development of domestic plastic materials. Some domestic enterprises in the processing of plastic wood materials and products, often overlooked the problem, no matter what recycled plastic with the same formula and process processing, product quality and stability of course can not be guaranteed. Over time, the user also lost confidence in the plastic wood products. Therefore, with the expansion of application areas, how to further improve the performance of plastic wood materials has become the focus of scientific research personnel development, plastic wood production process improvement, the development of special equipment and additives selection, but also need to further strengthen the study.
