Verfahren zur Herstellung einer thermoplastischen Kunststoffolie und deren Verwendung als Puffermaterial.

摘要

A thermoplastic resin film is disclosed which comprises a matrix in the form of a film and formed of a first thermoplastic resin (2), and a plurality of substantially continuous tapes (3) dispersed within the matrix film with the plane of each of the tapes being substantially parallel with the plane of the matrix film and each formed of a second thermoplastic resin different from the first resin. The thermoplastic resin film may be obtained by mixing melts of the first and second resins using a static mixer (12), and extruding the mixed melt through a die (13). The film has an excellent gas barrier property and is suitably used for the preparation of cushioning materials.
