Experimental analysis of property variation in biaxially oriented polypropylene film(CBSX30 EH) during storage

Ajitanshu Vedrtnam, S.J.Pawar, Ramesh Pandey

It has been observed as potential problem by many of the polymer manufactures that the polymer films like Biaxially Oriented Polypropylene (BOPP) experience degradation in their properties during storage. Usually, if not complete stock of films, than at least 10-20% of the complete stock experiences properties degradation. The present study is conducted for finding out the extant of variation of film properties like frictional coefficient, haze, gloss, and tensile strength. BOPP film is analyzed after subjecting it to aging and aging in sunlight/artificial light that cause accelerated aging. It was concluded that the storage condition affect the properties of BOPP Film. The film experiences maximum degradation if subjected to artificial light and least degradation when kept in dark. The remedies against degradation are also suggested.
