Studies on starch filled PE (film) and PP (sheet)

摘要

RECYCLING of plastics in India is not organised in a well planned manner. The packaging films like PE, PP, are the largely consuming plastics materials which should be effectively recycled, unless properly not recycled, there will be large environmental pollution and more difficulty for the solid waste management and its disposal during land filling. since these polymers are not inherently photo degradable or bio-degradable and it will take millions of years to degrade into small fragments. Hence, the incorporation of bio-degradable polymeric additives like starch are more important which accelerate their disintegration and degradation of the plastics materials within a short period of time.Starch is an inexpensive, and abundantly available natural resource, which decomposes very quickly in presence of water. Hence in this present study, starch was blended with LDPE/PP using a twin screw compounding extruder using glycerol as compatibilizer.
