Disposable products are increasing rapidly due to packaging, delivery, and courier effects because of the recent pandemic. As interest in the environment increases, materials used for packaging are also being replaced with materials that have a low environmental load when discarded. In this study, bio-degradable hot melt adhesive (HMA) was prepared from PBAT (Poly(butylene adipate-co-terephthalate) which is a well-known biodegradable polyester and rosin maleic resin for packaging. The result indicates the samples with 30 wt.% RM, which significantly enhanced the adhesion strength of PBAT from 1.8 to 7.3 MPa. While the additional excess of 40 wt.% or more RM caused deterioration of adhesion. To examine the adhesion properties of rosin maleic resin as a tackifier as the biodegradable polymer. Mechanical and rheological properties were measured using UTM, DSC, DMA, Rheometer. |
