The manufacture comprises extrusion onto a fibrous substrate (1) one or more polymer coating layers including at least one layer (2) of a polymer blend consisting of (i) 20–95 wt-% of polylactide having a high melt index of more than 35 g/10 min (210 °C; 2.16 kg), (ii) 5–80 wt-% of polybutylene succinate (PBS) or a biodegradable derivate thereof, and (iii) 0–5 wt-% of one or more polymeric additives. The components of the blend are melted and blended in connection with the extrusion step. The goal is to improve extrudability, increase ma- chine speed in extrusion and maintaining good adhesive- ness to the substrate and good heat-sealability of the coat- ing. The products include disposable drinking cups and board trays, as well as sealed carton packages for solids and liquids.

Abstract: The invention relates to methods for lowering the melt viscosity and thereby improving heat-sealability of a polyester. The invention also relates to a method for manufacturing a heat-sealed container or package from fibrous- based, polyester-coated packaging material, and a method for heat-sealing polyester. The solution according to the invention is subjecting polyester to electron beam (EB) radiation. The lowered melt viscosity allows a lower heat- sealing temperature, and permits sealing of polyester to an uncoated fibrous surface. The preferred polyester for the invention is polylactide, as such or as blended with another polyester.
