Extrusion Blow Molding

Extrusion Blow Molding

Extrusion blow molding is a process for manufacturing hollow bodies. Polyolefins such as LDPE, HDPE and PP are the most typical materials used.

Effect pigments develop their full optical effect
Effect pigments are excellently suited to the extrusion blow molding process, since the extrusion process guarantees that platelet-shaped effect pigments are aligned evenly to the surface so they can develop their full optical effect.

Co-extrusion is an efficient option for combining high coverage and good effects. Strong pearl luster and other effects can be achieved with a thin outer layer, while the desired opacity is created by the covering inner layer.
