Process
Allows finished products with complex shapes to be obtained in a single operation, in a variety of weights ranging from a few grams to several kilograms. The raw material is first mixed (once fluidised after being heated) in a worm screw and then injected into a closed mould.
For which products ?
Jars, pill boxes, caps, bucket lids…
Injection blow moulding is used for the manufacture of botlles. An injected preform is then pressed by compressed air against the walls of a mould and cooled.
For which products ?
Bottles, flasks, jars, pill dispensers…
Extrusion is a continuous transformation process of 100% green PE and HDPE.
It consists of introducing the plastic in powder or granular form into a heating cylinder inside which it is pushed by a screw. As it advances, the material softens, compresses and then passes through a die which gives it the desired shape.
Co-extrusion improves this process by adding several layers of material to produce a product that benefits from combined properties.

Cans, bottles, jars…
