木塑复合板材是一种主要由木材（木纤维素、植物纤维素）为基础材料与热塑性高分子材料（塑料）和加工助剂等，混合均匀后再经模具设备加热挤出成型而制成的高科技绿色环保材料，兼有木材和塑料的性能与特征，能替代木材和塑料的新型环保高科技材料 ，其英文 Wood Plastic Composites 缩写为WPC。
Wood-plastic composite board is a kind of high-tech green environmental protection material, which is mainly made of wood (lignocellulose, plant cellulose) as the basic material, thermoplastic polymer material (plastics) and processing additives. It can be replaced by wood and plastics because of its properties and characteristics. Wood Plastic Composites, the new environmentally-friendly high-tech material for wood and plastics, is abbreviated as WPC.
