Actually , it isnot
I know only 2 companies who do the PIB master-batch so i am asking for more info , or may be other new material has come up in the market that do same effect .
I am seeking for relaible alternative grade for the PIB cling additive for strech film or even if there are any alternative stick material or formulation .
strech film is either blow or cast film or thickness 15-20 micron onwards .
THanks
