Suitability of paper and board

For optimum results lamination is best carried out on papers and boards with flat, smooth, and hard coated surfaces, and low absorption characteristics. The substrates should also be reasonably dimensionally stable in relationship to changes in moisture content and atmospheric humidity. Many kinds and thicknesses of these substrates can be used but the quality of the final finish will be relative to the original quality of the selected substrate. Substrates should be non-yellowing on exposure to natural daylight.
