Abstract:
Paper packaging laminated with polypropylene (PP) film can be adhere by hotmelt adhesive. However peel strength of adhesive from film surface will vary with the formula of the hotmelt adhesive. In addition of optimum base polymer, additivs are effectively improve the peel strength. Ethylene vinyl acetate copolymer (EVA) is base polymer normaly used for hotmelt adhesive because of good adhesion and low cost. When add wetting agent, plasticizer, wax and antioxidant at different ratio, these will effect the peel strength. And from experimental design, we can forecast the best formula.
