Eco-design is a central concern for us, so we view our recent acquisition of 36 fully electric injection moulding machines as an opportunity for us to develop greener energy sources.

We are the only French manufacturer with such a large fleet of machines, enabling us to offer our customers greener, more sustainable products. Switching to fully electric operation is synonymous with green electricity, with no water pollution and the lowest energy consumption on the market. We are adding to this environmental approach by replacing all our dryers with ultra-low-consumption models.

What is extrusion blow moulding?

Plastic extrusion blow moulding is a process used to manufacture hollow plastic objects.

  • A hot plastic tube is cut in two and a cold mould is positioned around it.
  • Air is injected into the tube so that the plastic material is forced against the internal surfaces of the mould.
  • The mould is then cooled rapidly so that the tube, which has now become a plastic packaging product, can be removed.

To change the shape of the bottle, we just change the mould.
