India’s Uflex has developed a new range of blister packs featuring a special polyester film for use in the cold-formed pharmaceutical packaging industry.
The film replaces the bi-axially oriented polyamide (BON) and conventionally polyvinyl chloride (PVC) films used by conventional cold-formed aluminium-based laminate solutions.
Alu blister packs include three film layers comprising 36μm special polyester and 50μm soft aluminium foil.
Uflex technical and new product development (films) president PramodSirsamkar said: “The moisture absorption of this specialised polyester film is as low as 0.8% working out to almost 92% less than that of Nylon which is a big advantage.
"We are working towards offering high-barrier (yet thinner) speciality polyester films as an alternative to aluminium foil that may further lead to the reduction in overall weight of the ensuing laminate.
“The introduction of specialised polyester film in Alu – Alu blister packaging as a replacement for BON and PVC films has also opened up avenues for us to come up with biodegradable and oxo-degradable variants further minimising the carbon footprints.
"We are also working on developing such speciality films using recycled polyester and Green PET that will bolster our commitment towards the environment.”
The company will showcase the new film and other products at Asia Pharma Expo 2017, to be held in Bangladesh next week.
