Patent AT-E401193-T1: [Translated] METHOD FOR PRODUCING A COMPOSITE MATERIAL FOR LOCKING ELEMENTS AND USE THEREOF

The invention relates to a composite material (1), for closure elements, mad from a support material (2) and a thermoplastically moulded layer (3) with projecting and recessed sections (4,5). According to the invention, the thermoplastically moulded layer (3) is thinner in the region of the recessed sections (4) than in the region of the projecting sections (5). Said surface structure may for example be produced by embossing by means of ribbed rollers or embossing plates. The composite material (1) is suitable for the production of sealing elements, such as for example, cup tops, usually stored in stacks. The cup elements stacked thus can easily be unstacked after stacking, precisely by means of said recessed or projecting sections(4, 5). On the side of the composite material facing the consumer a decorative and/or informative impression (6) can further be provided.
