Plywood and other man-made boards such as blockboard, MDF/HDF, OSB, hardboard, particle board are produced under high temperature (110℃ ~140℃) and high pressure . Plywood is a panel consists of some plies of veneers. The veneers are peeled from wood logs, like hardwood, birch, poplar, oak, pine, etc.These wood veneers finally will be bonded together with adhesive under high pressure and high temperature (110℃ to 140℃).
In the production process under heat, all the harmful pests and insects in these man-made boards will be killed. Because of no pests and insects, plywood and these man-made boards won’t be required for fumigation. The packing materials like pallets, boxes made of plywood and man-made board are also not required for Fumigation.
