PREPARATION OR PRETREATMENT OF THE MATERIAL TO BE SHAPED

**Definition:** This place covers:

The mechanical preparation of plastic material as raw material used in subsequent plastic shaping techniques which form a final product ( B29B7/00 , B29B9/00 , B29B13/00 and B29B15/00 ).

The making of preforms used as an intermediate product which will udergo an additional processing step, e.g. blow moulding, to obtain the final product ( B29B11/00 ).

The recovery of plastics from waste products in order to reuse it for making new products ( B29B17/00 ).

**Glossary:** - A plastic: is defined as a macromolecular compound or composition based on such a compound. - In a plastic state: refers to a state in which the material is more or less easily deformable, locally or as a whole, by force in any direction, to assume and retain any desired shape.
