- O2 Barrier 2IN1 Underlay Film Used for Coverage



Greater work efficiency: With Polydress O2 BARRIER 2IN1, the underlay film used for coverage is attached to the silage film. This enables you to cover a silo in just one working step. This means that your work effort will be significantly less than with traditional silage films.

Independent film separation
Polydress O2 BARRIER 2IN1 already attaches to the silage while it is being covered. In absorbing moisture from the environment, the underlay film separates itself independently from the silage film after a few days, nestling on the surface of the silage.

Excellent silage quality
The special barrier characteristics of the polyamide underlay film, including an oxygen barrier that has been improved by a factor of six to ten, prevent the entry of oxygen into the feedstock. This leads to reduced fermentation losses and minimal mold formation, ensuring higher-quality silage.

Good accessibility
Although the film combination is only half as thick as a conventional cover consisting of two separate films, one can walk on Polydress O2 BARRIER 2IN1 without hesitation. For the absorbed moisture increases the strength, elongation and puncture resistance of the underlay film.

Secure sustainability
The separation of the two materials in use supports a sustainable recycling concept. As 40% less raw material is required for the production of Polydress O2 BARRIER 2IN1, as well as 50% less packaging materials, the film also makes a significant contribution to environmental protection, while also reducing disposal costs.

Outstanding innovation
The application and environmental benefits of Polydress O2 BARRIER 2IN1 also convinced the experts of the DLG Innovation Commission at the EuroTier 2012. Its international jury awarded a silver medal to the new silage film from RKW – not the first prestigious award for the film.

Polydress O2 BARRIER 2IN1 is the world’s first combination of a polyethylene silage film and a polyamide underlay film. The silage film innovation from RKW offers compelling work and environmental benefits and guarantees high, stable silage quality.
