Cosmo Films has launched BOPP-based universal lidding films, which are suitable for heat sealing to any of the rigid thermoformed cups/containers made up of PP/HIPS/PET/PVCor PE. The films are generally used for lidding of unit packs of packaged drinking water, juice, yogurt, jelly, jam, marmalade, butter etc., as well as trays used for packing salads, meals and fresh fruits etc. BOPP used for lidding applications scores over its counterparts in terms of sustainability, yield and therefore cost, better aesthetics and fold/flex resistance.

These films are available in white opaque cavitated and semi-transparent variants. BOPP film-based lids are safe for direct food contact, as no solvent is involved and ingredients involved in the manufacturing of this product are approved by FDA. The films offer excellent peelability, printability with water and solvent based inks and high aesthetic appeal. The films offer good moisture barrier properties as well.

The films can be easily diecut and punched, and display good stiffness for dispensing.  The films can be used for both inline and offline lidding processes. The product is available in standard thickness of 50, 75 and 85 microns. Other microns are also possible on demand.

"We saw both end consumers and printers facing challenges while using unit packs especially for packaged drinking water," says Pankaj Poddar, CEO of Cosmo Films. "The consumers invariably found it challenging to peel open the pack without spilling, and the label printers faced issues with finding the right adhesives for heat sealing of the lidding film. Looking at the need gap, we have developed a cost effective universal product where all that the printer needs to do is to print, diecut and supply the film to the brand. The film can also be sealed at lower sealing temperatures of 140-150 degrees."
