Beschreibung
Zusammenfassung:	The present invention discloses one kind of polylactic acid sheet and its production apparatus, and belongs to the field of polymer sheet making and plasticizing apparatus. The polylactic acid sheet in the thickness of 0.2-2 mm and drawing ratio up to 1 to 2.3 may be adhered to paper or fiber fabric to form compound material. The polylactic acid sheet is extruded in a screw extruder with a barrier type screw bolt, which has at least one ring notch between the barrier section and the top and raised rings beside the notch with homogeneously distributed shallow slots. The cooling drum is provided with at least 3 cooling water channels. The production apparatus of the present invention can produce polylactic acid sheets with excellent performance continuously.
