PLA based Biodegradable Films
Plastic is used extensively as packaging material due to obvious advantages. disposal of plastic is one of major environmental concern, in an attempt to find solution to this problem, fourteen variants of starch (cassava, corn, maize, rice and potato, 5-30%) and PLA based biodegradable films using commercial blown film extrusion have been developed. The oxygen transmission 32rate (106-318 cm/m.day), water vapour transmission rate (832413 g/m.day) and tensile strength (22-56 MPa), of the developed film are comparable to the conventional polymeric films.
