Abstract
Description
a) ラッカーなどの随意の高分子塗膜層
b) 随意の印刷層および/または着色層
c) カートン層
d) 随意の高分子接着層、たとえば、ポリエチレン(PE)層
e) 随意の障壁層、たとえば、アルミニウム(Al)箔障壁層
f) 内部熱可塑性層
を有し得る。内部熱可塑性溶接層は、ポリエチレン(PE)層および低密度ポリエチレン(LDPE)層など、2つ以上の副層から成り得る。副層は、共押し出しされて内部熱可塑性層を形成してもよく、または一緒にラミネート加工される別々の塗膜および/またはフィルムとして形成されてもよい。ラミネート本体シート材料の内部熱可塑性層は、本明細書では、ラミネート本体シート材料の熱可塑性溶接層とも呼ばれる。
本明細書で提示するように、容器本体および基部ディスクの材料に使用されるシート材料は、主に、板紙材料内でカートン層を形成するセルロース繊維または紙繊維で作られる。カートン層は、単層または多層の材料であり得る。シート材料は、カートン層に加えて、フィルムもしくは塗膜層の形態の少なくとも1つの熱可塑性高分子層と、随意に金属箔層、好ましくはアルミニウム層とを含むラミネートである。存在するとき、金属箔層は、少なくとも1つの高分子層でカバーされ、梱包容器の内面を形成することになるカートン層材料の表面において、すなわち、梱包容器の内側の方に向くことになる表面において配置される。高分子および金属箔の内層に加えて、シート材料は、塗膜、印刷、スコアリング、エンボス加工などを施され、当技術分野で知られている充填材、顔料、結合剤、および他の添加物を含み得る。本明細書で開示するシート材料は、板紙、ボール紙、またはカートン材料と呼ばれることがある。
