Indian packaging films manufacturer Cosmo Films has unveiled a cast polypropylene (CPP) metalised film with high metal bond strength.

The company developed the film to offer superior interlayer bond strength for making multi-layer laminate structures, which will, in turn, lead to enhanced barrier properties.

According to the company, CPP provides better seal strength, good thermal stability, good yield economics and good puncture resistance.

The film is available in standard thicknesses ranging from 20 to 30 microns and provides a metal bond strength of around 450gm/inch.

“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.”

It has a High Hot Tack and Low SIT of 96°C to 98°C, which enables FFS machines to run at a higher speed, thus helping improve productivity. The metalised film also offers superior heat seal strength of 2.5kg/inch.

The film can be used for several product categories, such as biscuits and snacks, bakery products, chocolates, chewing gums, dairy products, and spices.

Cosmo Films CEO Pankaj Poddar 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 interlayer bond strength which ultimately improves barrier properties, making it an ideal choice for food packaging applications.”

CPP film, which is known for its versatility, provides better seal strength as well as good moisture and gas barrier

The company offers different variants of CPP films, including transparent, white opaque and metalised for multiple applications.

Cosmo Films develops speciality films for flexible packaging, lamination and labelling applications. It offers bi-axially oriented polypropylene (BOPP) films, and cast polypropylene (CPP) films.

The firm is a major producer of thermal laminating films with operating facilities in the US, Korea and Japan.
