How and where is plywood produced?

Plywood is manufactured by slicing or rotary peeling thin (<2.5 mm) sheets of material (veneer) from a flitch or log, and then laminating three or more veneers into a rectangular sheet --- perhaps 1200 mm × 1200 mm for very thin sheets otherwise 1200 mm × 2400 mm. Laminating an odd number of plies (3, 5, 7 ... ) reduces warping. Increasing the number of plies increases the resistance to shearing forces.
