Uflex’s Flex Films Division Develops Special Polyester Film for Pharma Packaging

Uflex Limited’s Flex Films division has developed a special polyester film designed to replace the top and bottom substrates of conventional cold-formed laminates in blister packaging.

The special polyester is a para-crystalline material that possesses excellent barrier, clarity, printability and hardness properties. Film forming and orientation of polyester augurs well for the creation of thin profile webs with excellent properties for use in flexible packaging. This speciality substrate can be laminated on both sides of the aluminium foil. What’s more is that engineers at Flex Films have been successfully able to bring metaphase morphology, which has made it possible to form the film in the Z direction, which is a prerequisite for blister packaging.
