Title
(EN) HEAT-RESISTANT PACKAGING BAG AND METHOD FOR MANUFACTURING SAME
(FR) SAC D'EMBALLAGE RÉSISTANT À LA CHALEUR ET SON PROCÉDÉ DE FABRICATION
(JA) 耐熱性包装袋及びその製造方法
Abstract
(EN)
The heat-resistant packaging bag according to the present invention comprises a multilayer film having at least a substrate layer formed of a polyester resin, and a polyester resin-based functional resin layer adjacent to the substrate layer, each of the substrate layer and the functional resin layer being formed of a co-extruded laminate film, to thus include a layer having properties required from a packaging bag. The present invention also reduces the number of laminates, to lead to excellent productivity, economic efficiency, and flavors.
(FR)
La présente invention concerne un sac d'emballage résistant à la chaleur comprenant un film multicouche ayant au moins une couche de substrat formée à partir d'une résine de polyester et une couche de résine fonctionnelle à base de résine de polyester adjacente à la couche de substrat, chacune des couches de la couche de substrat et de la couche de résine fonctionnelle étant formée à partir d'un film stratifié co-extrudé, pour comprendre ainsi une couche ayant des propriétés requises d'un sac d'emballage. La présente invention réduit également le nombre de stratifiés, pour conduire à une excellente productivité, à une rentabilité et à des arômes.
(JA)
本発明の耐熱性包装袋は、ポリエステル樹脂から成る基材層、該基材層に隣接するポリエステル樹脂をベースとする機能性樹脂層を少なくとも有する多層フィルムから成り、前記基材層と前記機能性樹脂層が共押出による積層フィルムから成ることにより、包装袋に要求される性能を有する層を備えると共に、ラミネート回数が低減されており、生産性及び経済性並びにフレーバー性に優れている。
