(FR) BANDE DOUBLE FACE, SON PROCÉDÉ DE FABRICATION ET DISPOSITIF ÉLECTRONIQUE COMPRENANT LADITE BANDE DOUBLE FACE
Abstract
(EN)
The present disclosure relates to a double-sided tape, a method for producing the same, and an electronic device including the same. Specifically, according to one embodiment of the present disclosure, a double-sided tape may be provided, which may include: a first group layer and a second group layer stacked sequentially in one direction, in which the first group layer includes a first outer adhesive layer and a first film layer, which are sequentially stacked in the one direction, and the second group layer includes a foam carrier layer, a second film layer, and a second outer adhesive layer, which are sequentially stacked in the one direction, in which one of the first film layer and the second film layer is a polyethylene layer.
(FR)
La présente invention concerne une bande double face, son procédé de fabrication, et un dispositif électronique comprenant ladite bande double face. Plus particulièrement, un mode de réalisation de la présente invention porte sur une bande double face qui peut comprendre : une première couche de groupe et une seconde couche de groupe empilées séquentiellement dans une direction. La première couche de groupe comprend une première couche adhésive externe et une première couche de film, qui sont empilées séquentiellement dans ladite direction, et la seconde couche de groupe comprend une couche de support en mousse, une seconde couche de film et une seconde couche adhésive externe, qui sont empilées séquentiellement dans ladite direction, la première couche de film et/ou la seconde couche de film étant une couche de polyéthylène.
