In tropical regions, the hygroscopic sensitive products packaging need to be of high quality. PVdC coated PVC films manufactured by Uniworth are considered as best for the blister packaging due to the coating over rigid PVC films. The PVdC coating of optimum thickness on one side of the packaging minimizes the gas and moisture permeability.
The thickness of PVC ranges from 200 to 350 microns with coating GSM 20, 40, 60,90 and 120 GSM to suit the different pharma and food packaging requirements. Also, PVdC coated PVC film is produced as per current GMP norms and in compliance with pharmaceutical packaging regulations.
