Cosmo Films has upgraded its anti-fog film with cold and hot anti-fog properties as well as high hot tack and low co-efficient of friction, which can deliver high-speed overwrapping performance. This means that the film would now be suitable for the packaging of unpolished fruits in trays on high-speed HFFS machines.
Anti-fog films are generally transparent films that are used for fresh fruits and vegetables, salad packaging, and meat packaging applications. The high moisture content in these food items lead to mist formation on the film surface, thus affecting the visibility and perceived freshness of the food packed inside. An anti-fogging film not only prevents this phenomenon, but also renders the pack a better shelf appeal thanks to its enhanced gloss/optics. The film complies with the EC and FDA food contact regulations.
The film is a co-extruded, heat-sealable BOPP film, where printing is generally done on the top side with the inner side enabling the anti-fogging characteristics. The film works well in a single-layer as well as BOPP/AF BOPP laminate structure.
“The film has excellent machinability, high heat seal and high hot-tack strength, and low seal initiation temperature and, therefore, works very well on high-speed packing machines,” says Shailesh Verma, head of packaging films exports at Cosmo Films. “The film is available in 15 to 40 microns thickness. The company also makes film compatible for sealing on PE trays. A “keep fresh” grade providing longer shelf-life because of antibacterial properties is also available.”
