Recently, non-degradable plastics have been used excessively as disposable products, which has continuously caused environmental problems. Accordingly, the need for biodegradable polymers has emerged, and efforts have been made to apply biodegradable polymers in the field of adhesives. In particular, there have been concerns about environmental problems because the hot-melt adhesive uses polyolefin, EVA (ethylene vinyl acetate), which are known as non-degradable polymers. In this study, a hot-melt adhesive was prepared using biodegradable polymer and rosin (natural substances and used as a tackifier). It was identified that compatibility, surface properties, crystallization behavior, and surface morphology were changed by applying rosin and modified rosins with different acid values. As a result, it was confirmed that the adhesion to corona-LDPE film(replaced of LDPE coated paper packaging) was significantly changed and biodegradation can occur enymatically in PBS solution with lipase |
