Abstract
A method for manufacturing a laminated strip having a gas barrier material laminated in a liquid-tight manner between two external films includes the steps of forming surface irregularities in a first film, laminating a web gas barrier material to the first film, transversely cutting the gas barrier material and applying a second film over the gas barrier material. The apparatus for manufacturing the laminated strip includes a pair of cooperating rolls between which the first film is fed for forming irregularities in the first film. Two other cooperating rolls are provided for cutting the gas barrier member after it has been laminated to the first film. Two additional cooperating rolls are also provided for laminating the second film to the gas barrier material and the first film.
