This investigation focuses on the surface chemistry and roughness of substrates and the relationship to adhesion. We discuss the variability in surface chemistry and roughness of materials all nominally identified as the same material. For example, high density polyethylene (HDPE) is a common material used for bottles as well as a preferred low energy substrate for adhesion testing. However, there are several types of surface treatments used to increase adhesion. Surface roughness can also affect adhesion. We have compared corrugated cardboard surfaces and the influence of surface roughness on adhesion.
