Estimating the term…
The present invention relates to a biodegradable resin composition for extrusion coating. Specifically, the biodegradable resin composition for extrusion coating, according to one embodiment of the present invention, contains 5 wt % to 95 wt % of polyhydroxyalkanoates (PHA) and has a melt flow index (MI) of 5 g/10 min to 60 g/10 min at 190° C. and 2.16 kg according to ASTM D1238, the PHA meeting a weight average molecular weight range of 30,000 g/mol to 1,200,000 g/mol, and thus can achieve processability and mechanical properties such as excellent thermal adhesive strength even at low temperatures.
A biodegradable resin composition for extrusion coating, which comprises a polyhydroxyalkanoate (PHA) in an amount of 5% by weight to 95% by weight and has a melt flow index (MI) of 5 g/10 minutes to 60 g/10 minutes when measured at 190° C. and 2.16 kg according to ASTM D1238, wherein the PHA has a weight average molecular weight of 30,000 g/mole to 1,200,000 g/mole.
A process for preparing a biodegradable laminate, which comprises preparing a biodegradable resin composition for extrusion coating;
