    • PROBLEM TO BE SOLVED: To provide a lid material capable of reducing stringiness in opening without lowering easiness in opening.SOLUTION: A lid material used for a container having a seal part formed of a polyethylene resin comprises: a base material 1; and a sealant layer 7. The sealant layer 7 has a laminate structure formed by laminating a first thermoplastic resin layer 8 having adhesive strength for the base material and a second thermoplastic resin layer 11 having adhesive strength for the seal part formed of the polyethylene resin, and the first thermoplastic resin layer 8 and second thermoplastic resin layer 11 have thicknesses such that the thickness of the first thermoplastic resin layer 8 is less than or equal to the thickness of the second thermoplastic resin layer 11. The second thermoplastic resin layer 11 has a dispersion structure formed by dispersing a second thermoplastic resin 10 incompatible or partially incompatible with a first thermoplastic resin 9 in the first thermoplastic resin 9 so that 1.5≤l/s≤10, where l/s is the ratio of a domain short diameter "s" of the second thermoplastic resin 11 to a domain long length "l".
    • 要解决的问题:提供一种能够在不降低打开容易度的同时降低打开时的拉丝性的盖材料。解决方案:用于具有由聚乙烯树脂形成的密封部的容器的盖材料包括:基材1; 和密封剂层7.密封剂层7具有通过层叠具有基材的粘合强度的第一热塑性树脂层8和对由聚乙烯树脂形成的密封部分具有粘合强度的第二热塑性树脂层11而形成的叠层结构, 并且第一热塑性树脂层8和第二热塑性树脂层11的厚度使得第一热塑性树脂层8的厚度小于或等于第二热塑性树脂层11的厚度。第二热塑性树脂层11具有 通过将与第一热塑性树脂9不相容或部分不相容的第二热塑性树脂10分散在第一热塑性树脂9中形成的分散结构,使得1.5≤l/s≤10,其中l / s是区域短径 第二热塑性树脂11的长度“l”。
