UFlex’s global film manfacturing arm, Flex Films has released its new avant-garde patented BOPET high barrier film F-UHB-M. This has been designed as a substitute for aluminium foil in flexible packaging applications. F-UHB-M is aimed at addressing the challenges faced by the Converting Industry which has been dependent for long on aluminium foil for packaging, even though it is faced with plenty of limitations such as material availability, high material cost, weak integrity, propensity for in-use pinhole formation and difficulty in recycling.

F-UHB-M that comes with new specially formulated bi-axially oriented, polyester (BOPET) structure, contains superior gas and water barrier, while also having the capability of attaining one of the lowest oxygen and moisture barrier values (0.1 cc/ m2-day & 0.1 gm/m2-day respectively) and industry-leading metal adhesion of 1200 gm/25mm that aids improvement and extension of product shelf-life. Barrier performance is retained post incorporation of F-UHB-M into a multi-layer laminate structure exhibiting excellent handling, machinability as well as resistance to pin-hole formation.

Aluminium Foil Pinhole DamageFlex Films’ novel film offers a thickness of 12 microns and coating technology combined with a very high optical density is compatible with a vast range of inks and adhesives, has better machinability and handling during processing, generates lesser scrap during the process of production, possesses good flex crack resistance and 20% increased puncture resistance vs BOPET grades, an advanced in-line inspection mechanism in place to ensure consistency in barrier properties; and far less pinhole density than aluminium foils, making it less susceptible to gases and water vapour leakages. All of these provide the new BOPET film a strong competitive edge and makes it suitable for a whole host of flexible packaging applications, especially the ones dominated by laminate comprising of aluminium foil, placing it among the best in the packaging film industry.

3 ply Laminate Structure F UHB M FilmApart from its superior barrier performance and bond strength, F-UHB-M delivers multiple benefits for customers that range from cost efficiency, higher sustainability quotient to efficient use in logistics and e-commerce. One of the biggest challenges faced by the packaging film industry today is reduction of food wastage through enhanced shelf-life of food products, yet limiting packaging material consumption through laminate rationalization. F-UHB-M helps Converting industry move from a ‘difficult to recycle 4-ply laminate structure with aluminum foil’ to a ‘much simpler, easily recyclable 3-ply laminate structure with F-UHB-M film’ without compromising on barrier performance, thereby helping the customer achieve reduced laminate weight and lesser cost with minimized carbon footprint.

While the new high barrier film’s protective oxygen and moisture barrier system helps lock in flavours and aroma of food products for longer than those of products packaged in aluminium foils, the high metal bond strength ensures no delamination, thereby making the laminate a lot more secure and packed product safe and retain quality. These advantages come in very handy for the e-commerce industry, for which transporting products long distances in a safe and efficient way, without any damages, to their consumers is the name of the game.

The film is also FDA compliant and has been made to suit customer needs for applications in medical packaging; packaging for dried and powdered items such as dried meats, coffee, yeast, snacks and nuts; energy drinks packaging; vacuum insulated panels; bag-in-box and many more.

Vijay Yadav, Business Head, FLEXFILMS (USA) Inc. who had spoken on the benefits of this innovation, stated as follows – “Gathering market intelligence, the need to find a better replacement for conventional aluminium foil was established, which otherwise comes with quite a few limitations besides being highly sensitive to damages often compromising the barrier performance of packaging. While developing high barrier F-UHB-M, priority was given to upscale the barrier properties matching that of an aluminum foil to deliver the best packaging experience to our customers. Our teams have worked extensively on creating a real high value-added film with numerous benefits so that our converting partners gain from reduced manufacturing cost, much better performance and achieve economies of scale while going sustainable with their packaging at the same time. This film will act as a game-changer in the packaging industry, giving the industry a product like never before.”

Anantshree Chaturvedi, Vice Chairman & CEO, Flex Films further added on the new film’s potential and stated – “We are in business of offering solutions to challenges that packaging faces and one that complements evolving market needs. Customer-centric innovation helps us in introducing products that caters to the specific requirements of our clients. The F-UHB-M film has been developed keeping in mind the enhanced safety parameters and lesser complexities that converters want and green packaging that consumer seeks. With this film, we are accelerating our innovation strategy and delivering a solution that is sustainable and cost-effective.
