| titleOfInvention | A kind of preparation method of the polylactic acid film of the two-way high strength of high-crystallinity |
| abstract | The present invention relates to a kind of preparation method of the polylactic acid film of the two-way high strength of high-crystallinity, belong to resin film technical field；The method of the present invention comprises the following steps：PLA is extruded by single screw extrusion machine, is fitted to casting roller of the temperature rotated at a high speed at 50 ~ 100 DEG C using air-cooled technology after outlet mold, then after one 20 ~ 60 DEG C of chill roll, wind film forming；This method can obtain the polylactic acid film with the two-way high strength of high-crystallinity for being mutually perpendicular to crystalline texture using melt drawn and solid phase succeeding stretch technology. |
