BWP Great Plywood is constructed of three or more thin sheets of wood (called veneers) glued together, with each layer laid with the grain running at right angles to the next layer. Each sheet of plywood consists of an odd number of veneer sheets. The cross-hatching of the wood grain makes plywood stronger than boards and less susceptible to warping.

The BWP plywood is one of the most durable plywood. Its glue can be melamine or phenolic resin. To be considered exterior grade or marine grade, plywood must be produced with BWP glue. The best BWP plywood should be made with a phenolic glue.

BWP plywood made with ordinary melamine rather than phenolic resin can maintain lamination in boiling water 4-8 hours. Premium melamine glue can withstand boiling water for 10-20 hours. Premium phenolic glue can withstand boiling water 72 hours. It should be noted that the length of time plywood can withstand boiling water without delaminating also depends on the plywood veneer quality.
