The quality of the furniture sheet is very important. As we know, general furniture sheet is mostly plastic sheet plywood, also known as particle board. They are small pieces of wood debris material has been pressed by high pressure. Most of brand plastic used in the system cabinet plywood imported from Europe. The surface micro melamine material, through materials testing low formaldehyde class E1 V313 proof sheet, commonly used than the general store or V20 V100 plastic plywood better moisture resistance.  

     The system cabinet prices with EO grade plastic composite board（no Formaldehyde）is expensive than the E1 class 1.5 to 2 percent. Furniture manufacturing process, the use of channel adhesive, paint, hardware accessories is also very crucial. Adhesives and paints generally contain: formaldehyde, benzene, phenol, isocyanides and other harmful substances hazardous to human health. The EO standard used adhesives, paint, etc. in the formula do not contain these harmful substances, usually the more stringent standard sheet metal, leather, adhesives, paint, furniture and other manufacturing costs are relatively high, because, to strictly control the formaldehyde the zero release, in addition to low formaldehyde sheet attention, but also to take into account the density of the sheet. Plastic composite board density of about 0.66 ~ 0.72g/cm3, the higher the number the more solid panels, cabinets and more durable.   

     General sheet laminate thickness of about 1.8cm, however, there is 2.5cm and 2.8cm bookcase sheet selection. Sheet thickness and span force will affect the loading capacity of the cabinet, and now, though there have been manufacturers have introduced a thickness of 5 ~ 6cm thick plates, within High perch board, angle plate or adding Styrofoam to reduce weight. Application range mostly upright cabinet structural columns, tables and countertops, a few used in laminates.   Beside plastic composite board, some supplier also produces intensive board. Intensive board is pressed wood chips, sawdust, but has become a pressing powder. Its capacity is poor and easy bending after a long using.
