MDO PE films for sustainable and recyclable flexible packaging

Especially when it comes to plastic packaging for consumer goods, consumers are demanding more sustainability, as this is the only way they will be accepted in the long term. Therefore, the RKW ECORE® sustainability portfolio has been expanded to include mono-axially stretched PE films (MDO PE), which are marketed under the brand name RKW Horizon®. The RKW Horizon® product portfolio of MDO films is unique worldwide and includes highly transparent MDO films and print carriers, with oxygen barrier if desired, as well as white opaque variants.

When MDO PE films are laminated with a functional PE sealing film, the result is packaging made from a single raw material: polyethylene. Unlike many conventional pouch packaging, these are single-grade and therefore fully recyclable.

MDO films can be used for a wide variety of packaging forms, such as stand-up pouches, gusseted pouches, pillow pouches and sachets or as lid films. Areas of application are mainly the packaging of confectionery and snacks, coffee and tea as well as frozen foods, but MDO films can also be used in the non-food sector for the packaging of pet food, personal care products or cleaning and detergents.

Site investments form the basisAt the RKW site Petersaurach, one of the largest investments in new multilayer blown film lines was made for this purpose. A new five-layer extrusion film line and a new nine-layer extrusion line significantly expand the production capacities for high-quality sealing films and MDO-PE films. The Petersaurach site is ISCC+ certified and offers sustainable MDO films as well as bio-based films and films with a high recycled content (PIR and PCR) for a wide range of applications.
