摘要:
The invention provides a heat-shrinkable laminated film excellent in breakage resistance, stiffness, and shrink finish; and molded articles, heat-shrinkable labels, and containers, made by using the film. Specifically, a heat-shrinkable laminated film having a layer (A) constituted mainly of a polyester resin and a layer (B) constituted mainly of a polystyrene resin as the face and back layers or interlayers, in which the loss elasticity (EA") of the resin constituting the layer (A) exhibits at least one peak within the range of 50 to 900C and the storage elastic moduli thereof at 0 to 400C satisfy the relationship: EA'(0)/EA'(40) 1.5 x 108 Pa and EB'(90) > 5.0 x 10 7 Pa respectively, with the storage elastic modulus curves of E A' and EB' crossing each other and which exhibits a heat shrinkage of 30 to 60% in the direction of main shrinkage after the immersion in warm water at 800C for 10 seconds and a heat shrinkage of ±5% or below in the direction perpendicular thereto in the range of 70 to 800C.
摘要(中):
本发明提供耐破坏性,刚度和收缩精加工性优异的热收缩性层压膜。 以及通过使用该膜制成的模制品,热收缩标签和容器。 具体而言,具有主要由聚酯树脂构成的层(A)的热收缩层压膜和主要由聚苯乙烯树脂构成的作为面层和背层或中间层的层(B),其中损耗弹性(EA“) 构成层(A)的树脂在50〜900℃的范围内至少呈现一个峰值,其0〜40℃的保持弹性模量满足EA'(0)/ EA'(40)<1.2的关系,同时 在500℃和900℃下构成层(B)的树脂的储存弹性模量分别满足EB'(50)> 1.5×10 8 Pa和EB'(90)> 5.0×10 7 Pa的关系,其储能弹性模量 EA'和EB'彼此交替的曲线,并且在80℃的温水中浸渍10秒后,在主收缩方向上的热收缩率为30〜60%,热收缩率为±5%以下 垂直于其的方向在70至800℃的范围内。
