CA 2391525

The present invention provides a cover tape for packaging electronic components, which can prevent troubles associated with the peeling strength or appearing during mounting of the electronic components, which can be produced at a low cost, and which is transparent; that is, a cover tape which has a peeling strength not too high and not too low and small in difference between the maximum value and the minimum value and which has high transparency. Specifically, the present invention provides a cover tape for packaging electronic components, which can be heat- sealed to a plastic-made carrier tape having pockets capable of storing electronic components, formed regularly therein and which comprises (A) a biaxially oriented film layer made of a polyester, a polypropylene or a nylon and (B) a thermoplastic resin layer composed of 100 parts by weight of an ethylene copolymer and 10 to 100 parts by weight of a polystyrene, laminated to one side of the layer A.

Ruban protecteur pour l'emballage de composants électroniques qui prévient les problèmes associés au décollement ou qui se présentent au montage de composants électroniques, qui peut être produit à faible coût et qui est transparent; il s'agit d'un ruban protecteur dont la résistance au décollement n'est ni trop élevée ni trop faible, dont la différence entre la valeur maximale et la valeur minimale est faible, et qui est extrêmement transparent. Plus particulièrement, il s'agit d'un ruban protecteur pour l'emballage de composants électroniques qui se thermocolle sur un ruban porteur en plastique doté de pochettes à intervalle régulier pour y placer des composants électroniques, qui comprend (a) un film à double orientation en polyester, du polypropylène ou du nylon, et (b) une couche de résine thermoplastique composée de 100 parties en poids d'un copolymère éthylénique et de 10 à 100 parties en poids de polystyrène, laminé d'un côté.
