Corn Starch films were prepared as follows.
Aqueous suspension of 3g CS/100g with
plasticizers was preheated at 100oC for 30 min
in boiling water-bath, gelatinized at 160±5oC in
an oil bath for 30 min, cooled to 80oC, cast on
the round polypropylene (PP) plate (300mm
ID, 305mm OD and 10mm depth), and then
dried at 50oC for 24 h in an oven. Glycerol was
added to 100g of corn starch as plasticizers.
The dried powder from CS is then mixed with
the glycerol.
