Structure and properties of glycerin modified poly(lactiс acids) films

Abstract

The structure and properties of modified poly(lactiс acid) films suitable for use as packaging materials and paper lamination were studied. Modification of poly(lactiс acid) of different degrees of crystallinity with glycerol was performed. The influence of film formation conditions, the amount of glycerin plasticizer, the nature of poly(lactiс acid) on the structure, surface morphology and physical and mechanical properties of modified poly(lactiс acid) materials was studied. Modified film materials can be recommended for use in the packaging industry and paper lamination.
