Flex Films, the global film manufacturing of India’s multinational flexible packaging materials and solution company Uflex, has engineered a high-barrier metallised polyester film – Flexmetprotect F-HMB.
The film is either untreated or corona treated on the other surface, while metallisation is carried out on the specially treated composite surface imparting metal adhesion or bond strength of less than 1,200 gram-force/inch.
Steven Sargeant, GM, technology at Flex Films, said, “The adhesion of metal on BOPET base film is the sum of chemical and mechanical adhesion. Our proprietary surface treatment on the base film allows increased levels of chelation or reaction with the metal being deposited, thereby resulting in a much better adhesion profile. The specialized surface treatment comprises materials with unique and enhanced properties thereby leading to much enhanced mechanical bonding. It took us almost 18 months to engineer this film.”
According to Anantshree Chaturvedi, vice Chairman & CEO, Flex Films International, Flexmetprotect F-HMB is a a technologically superior film with encouraging demand. “If we talk about the US itself, the market for this specialized film is expected to be about 25% of the current metalised film market,” he said.
Uflex has plants in India, UAE, Poland, Egypt, Mexico and USA.
