The Films Business of Uflex team has come up with a special polyester film that obviates the problems posed by BON and PVC. PVC contains plasticizers with phthalates linked to health disorders that can damage the liver, kidneys, lungs and reproductive system. PVC film leaves high carbon footprint making it environmentally undesirable.
Polyester Film
BOPA (BON) is fraught with challenges such as high moisture absorption to the tune of 8-10% making its processing difficult; leading to de-lamination and impairing the ability of the film to be chemically primed.
Conventionally PVC and BOPA (BON) films have been used in cold formed pharma packaging industry. A typical alu–alu blister laminate comprises three layers ie.25 micron BOPA/ 60 micron soft aluminium foil / 60 micron PVC.
Eliminating BOPA and PVC films in the cold formed alu-alu laminate blister pack for pharmaceuticals has been a daunting task for packaging experts.
Uflex’s special polyester film is all set to replace the top and bottom substrates of the conventional cold formed alu–alu laminate to a whole new structure comprising 36 micron special polyester/ 50 micron soft aluminium foil/ 36 micron special polyester. This speciality film can be laminated on both sides of the aluminium foil without any problem.
