Title (EN) PACKAGING MATERIAL AND PACKAGING BAG USING SAME
(FR) MATÉRIAU D'EMBALLAGE ET SAC D'EMBALLAGE L'UTILISANT
(JA) 包装材及びこれを用いた包装袋
Abstract:
(EN) The present invention is a packaging material characterized in that: a primer layer and a low-adhesion coating layer having a grammage of 0.5–20 g/m2 are layered in this order upon one or both surfaces of a substrate; the primer layer includes an acid-modification product of a block copolymer comprising a block A which contains a structural unit derived from an aromatic vinyl compound and a block B which contains a structural unit derived from a conjugated diene compound, and/or an acid-modification product of a hydrogenation product of the aforementioned block copolymer; and the low-adhesion coating layer includes a cyclic polyolefin. The present invention causes minimal adhesion of medicinal components thereto, can be processed into a packaging bag without using an adhesive, and exhibits an excellent tear strength.
(FR) La présente invention est un matériau d'emballage caractérisé en ce que: une couche d'apprêt et une couche de revêtement à faible adhérence ayant un grammage de 0,5 à 20 g/m2 sont stratifiées dans cet ordre sur une ou les deux surfaces d'un substrat; la couche d'apprêt comprend un produit de modification d'acide d'un copolymère séquencé comprenant un bloc A qui contient une unité structurelle dérivée d'un composé vinylique aromatique et un bloc B qui contient une unité structurelle dérivée d'un composé diène conjugué, et/ou un produit de modification d'acide d'un produit d'hydrogénation du copolymère séquencé susmentionné; et la couche de revêtement à faible adhérence comprend une polyoléfine cyclique. La présente invention provoque une adhérence minimale de composants médicinaux à celle-ci, peut être transformée en sac d'emballage sans utiliser d'adhésif, et présente une excellente résistance à la déchirure.
(JA) 本発明は、基材の片面又は両面に、プライマー層及び坪量0.5~20g/mの低吸着コート層がこの順に積層され、前記プライマー層は、芳香族ビニル化合物に由来する構造単位を含有するブロックAと共役ジエン化合物に由来する構造単位を含有するブロックBとを含むブロック共重合体の酸変性物及び/又は前記ブロック共重合体の水素添加物の酸変性物を含有し、前記低吸着コート層は、環状ポリオレフィンを含有することを特徴とする包装材であり、薬効成分の吸着が少なく、接着剤を使用せずとも包装袋に加工可能で、なお且つ引き裂き性に優れる。
