Solid extrusion-winding is a manufacturing technology originally developed by Schoeller-Allibert, of which EELIX is now the sole holder. It is first and foremost for HDPE: the material is continuously extruded into thick strips, then wound in a spiral around a mandrel. The result: a single-piece, seamless tank.

HDPE and PP are two distinct thermoplastics. HDPE for concentrated acids and bases; PP for higher temperatures, food duty and potable water.

Extrusion-wound for large volumes and aggressive products. Bent-sheet for smaller volumes and mildly corrosive liquids.
