摘要

Being flexible, transparency to be high bleeding out is little, the thermoplastics constituent and the especially aliphatic polyester resin constituent which include the plastic medicine where the resistance extractability for the paraffin composition is high and this forming, the sheet, it offers the film or formation which become item. Vis-a-vis the aliphatic polyester 100 mass section, as a plastic medicine, being the polyatomic alcohol of the trivalent and the ester of the acyl basis of carboxylic acid origin of the carbon count 2-18, average acylation factor the specific ester compound of the 50-90% 1.0 mass section -100 mass sections is the aliphatic polyester resin constituent which features that it includes.
