What is plywood core?

Plywood core refers to the central layer of a plywood sheet, which is typically made up of multiple layers of thin wood veneers glued together. This core provides structural strength and stability, allowing the plywood to resist warping and bending. The type of wood used in the core can vary, affecting the plywood's overall properties, such as weight, durability, and cost. Common core materials include softwood, hardwood, and sometimes composite materials, depending on the intended application.
