Innovia Films has released Propacast KF, its new clear cast polypropylene film, which is specifically designed as a lamination solution for HFFS, VFFS and lidding applications.
Propacast KF, available as a 30-, 50- and 70-micron film, has a wide heat seal range, and offers good coefficient of friction and anti-block properties that ensures easy processing on a range of packaging machines, according to Innovia Films.
“With the drive towards simplified packaging formats, and the need to develop mono material structures, we developed this cast PP film to act as an inner sealing layer,” said Stephen Langstaff, business development manager of packaging at Innovia Films.
“This low temperature sealing film, when laminated to other PP films, such as our Propafilm CHS BOPP film with improved thermal resistance and shrinkage properties, creates an ideal structure for pouches.
“In the UK, this structure would be recognised by OPRL as fully recyclable.”
The Propacast KF has also been corona treated on one side to ensure suitable adhesion during lamination.
“This development will enable better recyclable formats to be created, ensuring the circularity of flexible packaging,” Langstaff continued.
“So far, all the feedback we have received about KF has been very positive.”
Propacast KF as a polyolefin film is fully recyclable, especially in countries which already have the infrastructure to recycle PP films.
