Beschreibung
Zusammenfassung:	The present invention relates to a plastic film obtained by (co)extrusion or by a multilayer extrusion process. The purpose of the invention is to supply a plastic film having useful properties, in particular of thermal behaviour, adhesion, linear tearability, and having a reduced production cost. This film contains lamellar particles based on at least one metal and/or at least one metal oxide. It is obtained by the extrusion of a raw material constituted entirely or partly by a ground material from at least one coated film comprising at least one polyester and/or polyolefin film and at least one coating film based on at least one metal and/or at least one metal oxide. The invention also relates to a method of manufacture of the raw material of the plastic film according to the invention, a method of manufacture of said plastic film as well as the uses of said film. Application in the field of packaging, decoration and heat treatments.
