Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a multilayer laminate film capable of suppressing adsorption of chemicals and additives to a support film, capable of stably releasing the chemicals, good in stable production and handling property, hardly generating followability to a surface part and expansion part of a body to be laminated and peeling, and almost no residue of an adhesive layer (C) on the body to be laminated during taking off the multilayer laminate film.SOLUTION: There is provided a multilayer laminate film by laminating a thin layer containing at least an ethylene-vinyl alcohol copolymer (EVOH) (B), an adhesive layer (C) containing chemicals and additives and a protective layer (D) on a supporter layer (A) The thin film (B) is constituted by a mixture of an EVOH resin and a polyolefin resin.SELECTED DRAWING: None
【課題】 化学薬品、添加剤の支持フィルムへの吸着を抑制することができ、安定的に化学薬品の放出が行えると共に、安定生産、取扱い性が良好であり、また被貼付体の曲面部、伸縮部への追随性、剥離が生じにくく、かつ 多層積層フィルム取外し時、被貼付体への粘着剤層(C)の残りがほとんどない多層積層フィルムを提供する。【解決手段】 支持体層(A)上に、エチレンービニルアルコール共重合体(EVOH)を少なくとも含む薄層(B)、化学薬品 及び 添加剤を含む粘着剤層(C)、保護層(D)を積層した多層積層フィルム。薄層(B)はEVOH樹脂とポリオレフィン系樹脂との混合物で構成される。【選択図】なし |
