The AW product range, due to its low density 0.91 gr/cm3, compared to traditional polystyrene-based films with a density of 1.05 gr/cm3, allows a reduction of up to 14% in the volume of plastics used for this application.

AW film is 100% recyclable and can be easily separated from paper allowing separate recycling. AW films have the main certifications for the postal market.

Since 2018 IFS has evolved the product with the AWR range, ultra-rigid films that allow to reduce the thickness used in each application.
