(Measurement condition) Between gripping tools: 50mm Tensile speed: 150 mm / min Peeling type: T-peeling
- the laminated body for tubes after aging was cut into a width of 15 mm and a length of 150 mm to obtain a test piece.
- Comparative Reference Example 1 using an ether-based main agent, the initial laminate strength was insufficient, so that laminate lifting occurred when stress was applied to the original fabric. Therefore, the tube laminate of Comparative Reference Example 1 has insufficient handling properties.
- Comparative Reference Example 2 ink layer aggregation peeling or PET surface layer peeling was observed after aging. Therefore, the tube laminate of Comparative Reference Example 2 is expected to cause surface layer peeling when an external force is applied to the end face during molding of the shoulder portion or the like.

チューブ用積層体は、機能性塗布層、表層、接着剤層、インキ層、及び基材積層体が、表側から裏側に向かってこの順に積層されている積層体である。
機能性塗布層は、チューブ用積層体の表側に機能性を与えるための層であり、かつ機能性材料の塗布により形成される。
表層は、チューブ用積層体からチューブを形成したときに表側を向く層である。表層は、機能性塗布層と接着剤層の間に配置される。
表層とインキ層の間におけるラミネート強度を向上させるためには、表層とインキ層を接着する接着剤層に対する機能性塗布層の影響を抑えて、接着剤層の接着力を確保することが好ましい。
接着剤層は、表層とインキ層を接着するための層である。接着剤層は、包装材料又はチューブ容器の分野で知られている接着剤で形成されてよいが、2液型接着剤で形成されることが好ましい。
エステル部分を有するポリオールは、耐熱性と、強い初期タックを有し、かつ耐内容物性に優れる。なお、初期タックは、被着材と接触させた直後から結合を形成して接着力を発揮する性質であり、初期接着性とも呼ばれる。
ポリイソシアネートは、少なくとも2つのイソシアネート基を有する化合物であり、ポリオールと架橋してオリゴマー又はポリマーを形成する。
インキ層は、インキで形成されている層であり、かつ基材積層体よりも表側に配置されている。インキ層としては、例えば、印刷層等が挙げられる。インキ層は、基材積層体の表面のシール部に対応する箇所に配置されていてよく、特に、基材積層体の表面の全てに配置されていてよい。ここで、シール部に対応する箇所とは、積層体を筒状にシールしてチューブに形成したときに、シール部となる積層体の領域をいう。本発明の特定の態様においては、インキ層が、基材積層体の表面のシール部に対応する箇所に配置されていることで、チューブのシーム部にさえも印刷パターンを形成し、特に、基材積層体の表面の全てに連続的な印刷パターンを形成して、チューブ容器の意匠性を確保することができる。
基材積層体は、インキを印刷される層である。基材積層体は、複数の層が積層されている積層体でよく、複数の同じ種類の層を含んでもよい。
チューブ用積層体は、以下の工程を含む方法により製造されることができる:
基材積層体にインキを印刷して、インキ層を形成する印刷工程;
基材積層体のインキ層側と、表層部材とを接着して、チューブ用積層体を得る積層工程;
機能性材料含有ニスをチューブ用積層体の表層部材側に塗布して、機能性塗布層を形成する塗布工程;及び
所望により、チューブ用積層体をエージングするエージング工程。
チューブ容器は、チューブ用積層体で形成された胴部を有する容器である。
チューブ用積層体を、基材積層体の非インキ印刷部分が裏側を向くように丸めながら、積層体の端部同士を重ね合せてシールして、胴部を得る工程;及び
胴部の開口部の周縁に、肩部及びキャップ部を有する頭部を結合させて、チューブ容器を得る工程。
