摘要：
The invention concerns a heat-sealable biodegradable packaging material, which comprises a fibrous substrate and one or more polymer coating layers extruded onto said substrate. According to the invention the packaging material includes at least one polymer coating layer containing polylactide and at least about 1 weight-% of terpene phenolic resin blended therewith. The invention further concerns a heat-sealed product package made from the packaging material, as well as uses of the resin as blends with polylactide in extrusion coating, for improving line speed and neck-in in extrusion, adhesivity of the coating to the fibrous substrate, and heat-sealability of the coating.
