This product is a low density (LDPE) co-extruded film with an approximate thickness of 200 microns and it is used as a supplementary cover for ductile iron, metal or plastic pipes. This film is known as an inexpensive encasement (tubular protection) for underground pipelines against corrosive soils and it is mostly applied in road and construction industries.

Polyethylene Encasement
Since these films are mostly used for underground pipes, they should be manufactured according to ISO8180 standard and in order to achieve high resistance and durability, certain additives are required to be added while producing the film.
Typically, some soil moisture penetrates into the casing, which initially can cause corrosive properties, however, the oxygen content under the casing will run out soon and the oxidation process stops quickly.
It is recommended to use this film in the following cases:
- Soil with low electrical resistivity, which indicates the high corrosive properties.
- Soils with high levels of sulfates, chlorides or bacterial activity.
- Areas with severe dust and storms.
