Example Embodiment
[0014] Example 1
[0015] Pulverize the corn stalks to become 120 mesh powder, select wood-plastic coupling agent, calcium stearate and white oil as plastic additives, and mix with film-blown polylactic acid; corn stalks, wood-plastic coupling agent, calcium stearate , white oil, blown film grade polylactic acid were 20 parts, 5 parts, 2 parts, 1.5 parts, and 70 parts. Then it is extruded and pelletized by a twin-screw extruder. The plastic particles produced by this method are blown into a film by a single-screw extruder to produce a film product with a corresponding filling content.
Example Embodiment
[0016] Example 2
[0017] Pulverize the corn stalks to become 120 mesh powder, select wood-plastic coupling agent, calcium stearate and white oil as plastic additives, mix with film-blown polylactic acid, corn stalks, wood-plastic coupling agent, calcium stearate , white oil, blown film grade polylactic acid were 25 parts, 4 parts, 2.5 parts, 2 parts, 65 parts. Then it is extruded and pelletized by a twin-screw extruder. The plastic particles produced by this method are blown into a film by a single-screw extruder to produce a film product with a corresponding filling content.
Example Embodiment
[0018] Example 3
[0019] Pulverize the corn stalks to become 120 mesh powder, select wood-plastic coupling agent, calcium stearate and white oil as plastic additives, mix with film-blown polylactic acid, corn stalks, wood-plastic coupling agent, calcium stearate , white oil, blown film grade polylactic acid were 30 parts, 4.5 parts, 2 parts, 2 parts, 60 parts. Then it is extruded and pelletized by a twin-screw extruder. The plastic particles produced by this method are blown into a film by a single-screw extruder to produce a film product with a corresponding filling content.
