Polydress® FarmGuard
Silage barrier film


Next generation films
with advanced e7-layer technology


  • Flexible widths from 8 m to 16 m / 32 ft up to 50 ft
  • Up to 100 times higher oxygen barrier than in standard silage films
  • Sustainable concept (resource-saving film, lower CO2 footprint, 100% recyclable)
  • Easy handling (less weight, no vacuum film necessary)
  • Highest durability (outstanding dart drop, high tensile strength)


Polydress® FarmGuard is a new high performance silage film based on Europe’s latest 7-layer technology and offers a full package of powerful features. Due to an outstanding oxygen barrier the ingress of oxygen in the feedstock is prevented and the silage quality remains at a high level for a long time. This avoids silage losses, preserves the nutritional value and allows a longer storage of the silage material.

Polydress® FarmGuard stands for peace of mind, because it is characterized by an unrivaled durability and resilience. Furthermore the film offers maximum sustainability like 100 % recyclability, less waste during the production process, less forage and no need of an additional underlayer film.
