Innovia Films is launching the newest addition to its Propafilm Strata range of transparent, high barrier, mono-material packaging films.  

SLF is a chlorine-free film that the company says delivers “exceptional barrier levels” to oxygen, moisture, aroma, and mineral oils. It has been designed with a wide sealing range, making it suited to high-speed horizontal-form-fill-seal packaging of biscuits, bakery, and confectionery type products. 

Alasdair McEwen, global product manager for packaging at Innovia Films, says: “With SLF, we have been able to develop a totally new barrier film that not only has outstanding oxygen and aroma barrier, but also has enhanced moisture barrier when compared with standard polypropylene films.

"This means that there is an opportunity to increase product shelf life and therefore reduce food waste. It is the perfect replacement for PVdC coated films.”

McEwen continues: “We have incorporated a wide sealing range polymer into the formulation of SLF, so it has been designed specifically for use on high-speed horizontal packaging lines.”

Innovia says that, like all Propafilm Strata films, SLF provides an effective barrier to aroma and oxygen – even at high relative humidity levels. It is also reportedly printable, glossy, and food contact compliant globally.

SLF has also been classified as “Made for Recycling” by Interseroh. McEwen, explains: “This certification proves the recyclability of our new Strata SLF film. It can be classified as ‘recycle ready’, or recyclable in countries which have the infrastructure to recycle polypropylene.”
