The new heat resistant films are clear, non-heat sealable films–with both sides treated. They provide 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 FFS packaging machines. Available in 15, 18, 20 microns, the films are well suited for both adhesive and 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, CEO of Cosmo Films, says, "Homogeneous structures are becoming increasingly preferable as recyclability of multilayer packaging becomes the need of the hour. Polypropylene structures, or even polypropylene plus Polyethylene structures, are better placed from recyclability perspective because they belong to the same polymer family. Cosmo Films, with more than 100 years of collective OPP experience, now stands in an advantageous position to develop specialized polypropylene films aimed at a sustainable future."
