Résumé : |
Various waste materials are produced in blow and flat sheet film manufacturing. This includes film residues, scrapped rolls, trimmings and purgings. Stamping grids and scrap parts are also generated in case of subsequent thermoform production. The zero scrap production concept of NGR is intended to return all waste material to the manufacturing process. |
