Manufacturing method of an eco friendly foaming package material

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 S40 for performing the shaping and foaming by putting the plastic particles in an extrusion machine, in which the plastic particles are melted into a gelatinous state material, and where CO2 or N2 is penetrated the gelatinous state material at the same time to foam with a non-chemical method, the foamed gelatinous state material is in form of a foaming plate material, finally the co friendly foam package material is obtained after cooling the foaming plate material,
• 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.
