Abstract:
1. A manufacturing method of an eco friendly foam package material, comprising: a raw material mixing step for thoroughly mixing a plurality of raw materials to form a mixed raw material; a raw material hybrid-melting step for performing the hybrid-melting process by putting the mixed raw material into a kneader at 80° C.˜100° C. for 1 to 3 hours to form a hybrid-melted material; a particle forming step for performing the particle forming process by putting the hybrid-melted material into a pelletizer to form a plurality plastic particles; and a foam extrusion step S wherein the raw materials at least include a biodegradable polymer 80˜120 phr, a decomposition enzyme 15˜25 unit/g, an interfacial compatibilizer 15˜25 phr, and additives 1˜10 phr.
