In media with non-porous substrates the ink receiving layer absorbs all inks. In porous substrates such as cellulosic, the substrate absorbs a significant amount of water and chemicals passing through the ink receiving layer. A difference in absorption between two types of media has an effect on interactions with lamination films. A dozen commercially available media were printed with several inks and laminated. It was found that laminating adhesion increases with the paper base weight. Peel strength is also dependent on type and characteristic of paper sheets. An interaction of inks with paper sizing agents can significantly reduce internal bond strength. The paper internal strength was frequently lower than the adhesion between laminating film and ink receiving layer and in the delamination test the paper was torn apart.
