<p>A film according to the present invention optimizes the productive process of slabs made of marble agglomerates because this film solves one of the main problems that arise in this kind of production, namely, the removal of the protective material such as paper, rubber etc. from the slab when the baking phase is concluded and before the beginning of the subsequent phases in which the slab is finished off. Basically, the detachable film in question is made of polypropylene (both copolymers and homopolymers) in its several forms such as cast, extruded, coextruded, mono-biorientated forms or further forms, or other similar material derived from polypropylene. Unlike polyester, polypropylene accomplishes its antiadhesive function very well on the marble agglomerate and therefore, polypropylene is used in the production of marble agglomerate.</p> |
