Balanced Laminate Panel

Laminate orientation code repeating groups of plies within a laminate can be placed in parentheses.

Balanced laminate panel.

No science that i know of but in my experience an unbalanced panel is more prone to warping than a balanced panel. If the laminates are of different thickness they will shrink at different rates pulling the panel out of flat. Each complete laminate is enclosed in a set of brackets symmetric laminates with an even number of plies are represented by listing all plies on one side of the mid plane enclosed in brackets followed by the subscript s. Here is a deeper explanation of both reasons for using a balance veneer.

An example of a balanced laminate is 0 45 45 90 45 45 0 whereas an unbalanced laminate would be 0 45. Fact is pre lam is cheaper than doing it in house and you get a better product because they use hard glue not contact. Melamine or tfm thermally fused melamine or lpl low pressure laminate. When a veneer is bonded to both sides of the panel each side is equally expanding and contracting and thus the panel is balanced the stress of the wood cell movement is similar on both sides of the panel.

This is produced in higher volumes than hpl. Cabinet liner is better than nothing but still not truly balanced. Melamine paper is thermally bonded to particleboard or mdf panels. We buy pre laminated panels as much as possible almost always with laminate both sides.

Sometimes a brown backer is applied to the bottom if color is not needed. If the laminate is not balanced and symmetric macro warpage will certainly occur during cool down.
