Hollow plastic plate, also known as corrugated board, double-wall is a new mid-eighties in the world of packaging material commonly used in developed countries. It is light weight, non-toxic, tasteless, non-polluting, water moisture, corrosion-resistant, anti-aging, rich facial features, is an alternative to cardboard boxes, plastic box ideal packaging material. 1, compared to the pasteboard products: with moisture, corrosion, and other advantages. 2, compared to injection products, with shock, the flexibility to design the structure, without opening the injection mold, and other advantages. 3, at the same time, the sheet can be controlled by a flexible material joined anti-static, conductive materials such as mother, to produce a conductive, anti-static plastic hollow board sheet function, anti-static sheet surface resistivity can be controlled between 103 ~ 1011 . (But there is one drawback is hollow plate is not cut a 90 degree angle, because the relationship between the sheet).
