About the problem and solution of warping of wooden boards:
Plywood is made of multiple layers of whole wooden boards, so they also have the problem of warping like natural wooden boards. This is caused by the change of moisture content inside, which is related to the change of humidity in the air.
Our plywood is inspected before leaving the factory and wrapped with plastic film to keep it flat. Please use it as soon as possible after we remove the plastic film. Please seal the unused wooden boards or place them under heavy objects.
If you have any other questions, please contact us. Thank you for choosing our products!
