Summary: | Disclosed is a film for a shrinkable label, which is a non-adhesive label with a specific gravity of less than 1, wherein the film has improved low-temperature shrinkability and stiffness while maintaining improved seaming characteristics and transparency. The present invention provides a film for a shrinkable label, which comprises a skin layer, a core layer, and a seal layer, wherein the skin layer and the seal layer contain a first polystyrene-based resin, the core layer contains: 40 to 90 parts by weight of a copolymer of at least two types of olefins selected from propylene, ethylene, and α-olefins; 5 to 30 parts by weight of a petroleum resin having a softening point of 120 to 140°C; and 5 to 30 parts by weight of a polyolefin elastomer, wherein tie layers containing a second polystyrene-based resin are provided between the skin layer and the core layer and between the core layer and the seal layer, respectively.
L'invention divulgue un film pour une étiquette rétractable, qui est une étiquette non adhésive ayant une densité de moins de 1, le film ayant une aptitude à la rétraction à basse température et une raideur améliorées tout en conservant des caractéristiques de couture et une transparence améliorées. La présente invention concerne un film pour une étiquette rétractable, qui comprend une couche de peau, une couche d'âme et une couche d'étanchéité, la couche de peau et la couche d'étanchéité contenant une première résine à base de polystyrène, la couche d'âme contenant : 40 à 90 parties en poids d'un copolymère d'au moins deux types d'oléfines sélectionnées parmi le propylène, l'éthylène et les α-oléfines ; 5 à 30 parties en poids d'une résine de pétrole ayant un point de ramollissement de 120 à 140 °C ; et 5 à 30 parties en poids d'un élastomère de polyoléfine, des couches de liaison contenant une seconde résine à base de polystyrène étant ménagées entre la couche de peau et la couche d'âme et entre la couche d'âme et la couche d'étanchéité, respectivement.
수축 라벨용 필름에 있어, 비중 1 미만의 비접착식 라벨로서 향상된 시밍 특성 및 투명성을 유지하면서, 저온 수축성 및 고시성이 향상된 수축 라벨용 필름이 개시된다. 본 발명은 스킨층, 코어층 및 씰층을 포함하는 수축 라벨용 필름으로서, 상기 스킨층 및 씰층은 제1 폴리스티렌계 수지를 포함하고, 상기 코어층은 프로필렌과, 에틸렌 및 α-올레핀 중에 선택되는 2종 이상의 올레핀과의 공중합체 40 내지 90 중량부; 연화점이 120 내지 140℃인 석유수지 5 내지 30 중량부; 폴리올레핀 엘라스토머 5 내지 30 중량부;를 포함하고, 상기 스킨층과 상기 코어층 사이 및 상기 코어층과 상기 씰층 사이는 제2 폴리스티렌계 수지를 포함하는 타이층이 구비된 수축 라벨용 필름을 제공한다. |
