Films and film products made of derivatives of starch or amylose

摘要

Film and film products (I) comprise starch and/or amylose derivatives produced from a starch or amylose derivative solution, preferably a starch or amylose-ether solution. (I) is characterized by a low salt content solution and various specified conditions. Film and film products (I) comprise starch and/or amylose derivatives produced from a starch or amylose derivative solution, preferably a starch or amylose-ether solution. (I) is characterized by a low salt content solution, an average molecular weight of 1 x 10<5>-2 x 10<7> g/mol; a degree of substitution of 0.1-0.5; a similar distribution of substitution between the 2C/3C and 6C binding sites within the glucose unit; a water content of less than 25 wt.% under normal conditions, a polydispersity of 2-8; an amorphous structure with a low crystalline content and a particle size of no greater than 400 nm.
