Cosmo Films, a global leader in specialty films for flexible packaging, lamination and labelling applications, has launched a cast polypropylene (CPP) metalised film with high metal bond strength. This film has been specially designed to offer superior inter layer bond strength for making multi-layer laminate structures, which, in turn, enhance barrier properties. They are use in food packaging.
Apart from CPP’s inherent nature of excellent seal strength, good thermal stability, good yield economics and good puncture resistance, the film provides exceptional metal bond strength of around 450g/inch.
Available in standard thicknesses ranging between 20 and 30 microns, this newly-developed metalised film has a High Hot Tack and Low SIT of 96 to 98 degree Celsius, which enables form-fill-seal (FFS) machines to run at a higher speed, thus helping improve productivity. This film also exhibits superior heat seal strength of 2.5kg/inch. Some of the typical applications of the film in food packaging are for biscuits and snacks, bakery products, chocolates, chewing gums, dairy products, etc.
CPP film is growing in popularity as a more attractive packaging material owing to its versatility. Cosmo offers different variants of CPP films like transparent, white opaque and metalised for multiple applications. It provides excellent seal strength, as well as good moisture and gas barrier, making it a material of choice for convertors and brand owners in the industry.
Speaking on the development, Pankaj Poddar, chief executive officer, Cosmo Films Ltd, said, “The latest addition of high metal bond strength film has definitely expanded our CPP portfolio and we see a huge potential for this film into flexible packaging. A strong metal adhesion is critical to get good inter-layer bond strength, which ultimately improves barrier properties, making it an ideal choice for food packaging applications.”
