Plywood production requires a good log, called a peeler, which is generally straighter and larger in diameter than one required for processing into dimensioned lumber by a sawmill. The log is peeled into sheets of veneer which are then cut to the desired dimensions, dried, patched, glued together and then baked in a press at 140 °C (280 °F) to form the plywood panel. The panel can then be patched, resized, sanded or otherwise refinished, depending on the market for which it is intended. VENEER: This refers to thin slices of wood, usually thinner than 3 mm, that are typically glued onto core panels (typically, wood, particle board or medium density fiberboard) to produce flat panels such as doors, tops and panels for cabinets, and parts of furniture.
