Document Type and Number:
WIPO Patent Application WO/2015/029877
Kind Code:
A1
Abstract:
Provided are a barrier laminate comprising a sealant film and a base material laminated together, the barrier laminate being capable of suppressing elution of an adhesive component that is a specific subject to be controlled while maintaining seal strength, and a package made using this barrier laminate. Specifically, a barrier laminate having a base material/adhesive layer/sealant film configuration is used, wherein the laminate is characterized in that the sealant film contains a cyclic olefin resin (a1) having a Tg of 160°C or less and an olefin resin (a2) having an MFR of 0.5-30 g per 10 minutes, the film having at least one layer (A) in which the thickness comprising a resin composition containing at least 30 mass% of (a1) in the total mass of (a1) and (a2) is within a range of 0.5-20 μm, and in the layer (A), either (a1) and (a2) form a layered phase-separated structure, or (a2) forms a phase-separated structure scattered as islands on a continuous layer of (a1).
