Abstract:
A process for preventing thermoplastic packaging films from slipping on each other characterized in that a system is formed which system comprises a binding element and films to be fixed at least one of the films to be fixed being rough, where such a roughed film is applied that has protrusions on its surface having suitable closeness and geometric features with respect to the binding element, and a binding element having a loose fibrous structure and individual fibre-stability is placed on one of the films at least on the entirety or part(s) of its parts to be bound with the roughed surface of the other film, which binding element comprises fibres of such closeness and layer thickness that between the fibres of the binding element and the protrusions of the roughed film a mechanical joint can be formed, and at least if a non-roughed film is applied as a part of said system a fixing is formed between the binding element and the surface part(s) of the film.
