, has launched BOPP-based heat-resistant (HR) films. The films have been engineered to work as printing layer-replacing BOPET film in multi-layer laminates for various packaging applications in both the food and non-food segments.
The new heat-resistant films are clear, non-heat sealable and both sides treated films with excellent printability and go mostly for reverse printing. The thermally-stable films have excellent slip properties and good machinability, and therefore work well on high speed form, fill and seal (FFS) packaging machines.
Available in 15, 18 and 20 microns, the films are well suited for both adhesive as well as extrusion lamination and offer good lamination bond.
The company has also launched a barrier version of the film. The transparent BOPP-based barrier HR film has excellent oxygen barrier properties and offers OTR of less than 100cc/m2/day. The film has good grease resistance that comes in handy for oily snack food packaging, which is a big application area of this film.
Speaking on the development, Pankaj Poddar, chief executive officer, Cosmo Films said, “Homogeneous structures are becoming increasingly preferable as recyclability of multilayer packaging becomes need of the hour.”
“Polypropylene structures, or even Polypropylene plus Polyethylene structures, are better placed from the recyclability perspective because they belong to the same polymer family,” he added.
“Cosmo Films, with over 100 years of collective OPP experience, now stands in an advantageous position to develop specialised polypropylene films aimed at a sustainable future,” Poddar said.
