Title:
LAMINATE FILM, BARRIER LAMINATE FILM, AND GAS-BARRIER PACKAGING MATERIAL AND GAS-BARRIER PACKAGED BODY EACH USING SAID BARRIER LAMINATE FILM
Document Type and Number:
WIPO Patent Application WO/2019/087960
Kind Code:
A1
Abstract:
Provided are: a laminate film in which the adhesion between a plastic base member and an aluminum oxide-deposited film is good even after a hot water treatment, and which is provided with an aluminum oxide-deposited film having high barrier performance, i.e., excellent retort resistance; a barrier laminate film including the laminate film; and a gas barrier packaging material and a gas barrier packaged body, in each of which the barrier laminate film is used. A laminate film having improved adhesion strength and barrier performance is specified as follows: an aluminum oxide-deposited film in the laminate film is subjected to a time-of-flight secondary ion mass spectrometry (TOF-SIMS) method using a Cs (cesium) ion gun to form a transition region, which specifies adhesion strength, between the surface of a base film and a deposited film mainly composed of the formed aluminum oxide-deposited film; the transition region contains an elemental bond Al2O4H which can be modified into aluminum hydroxide that can be detected by carrying out etching employing TOF-SIMS; and the modification rate of the transition region that is modified into aluminum hydroxide, which is defined by the ratio of the modified transition region to the aluminum oxide-deposited film specified by carrying out etching employing TOF-SIMS, is specified to 45% or less.
