Title (EN) MULTI-LAYERED PLASTIC FILM
(FR) FILM DE MATIÈRE PLASTIQUE À PLUSIEURS COUCHES
(DE) MEHRLAGIGE KUNSTSTOFFFOLIE
Abstract:
(EN) The invention relates to a multi-layered plastic film which consists of an outer layer (20) and an inner layer (40) as well as a barrier layer (30) which is disposed inbetween. Said barrier layer is joined to the outer layer (20) by means of a first adhesive layer (3) and is joined to the inner layer (40) by means of a second adhesive layer (4). According to the invention, the first adhesive layer (3) is more elastic than the second adhesive layer (4) or both adhesive layers are made from the same adhesive material. Said first adhesive layer (3) is thicker than the second adhesive layer (4).
(FR) L'invention concerne un film de matière plastique à plusieurs couches, comprenant une couche extérieure (20), une couche intérieure (40) et une couche formant barrière (30) qui est disposée entre les deux et qui est reliée à la couche extérieure (20) par une première couche adhésive (3) et à la couche intérieure (40) par une seconde couche adhésive (4). Selon l'invention, la première couche adhésive (3) est plus élastique que la seconde couche adhésive (4) ou les deux couches adhésives sont réalisées à partir de la même matière adhésive, la première couche adhésive (3) étant plus épaisse que la seconde couche adhésive (4).
(DE) Die Erfindung betrifft eine mehrlagige Kunststofffolie, welche aus einer äusseren Lage (20) und einer inneren Lage (40) sowie einer dazwischen liegenden Sperrschicht (30) gebildet ist, die über eine erste Klebschicht (3) mit der äusseren Lage (20) und über einer zweiten Klebschicht (4) mit der inneren Lage (40) verbunden ist. Erfindungsgemäß ist vorgesehen dass die erste Klebschicht (3) elastischer ist als die zweite Klebschicht (4) oder beide Klebeschichten aus demselben Klebmaterial gefertigt sind, wobei die erste Klebschicht (3) dicker ist als die zweite Klebschicht (4).
