Title:

GAS BARRIER PACKAGING MATERIAL AND METHOD FOR PRODUCING SAME

Document Type and Number:

WIPO Patent Application WO/2016/158444

Kind Code:

A1

Abstract:

This gas barrier packaging material is provided with a barrier layer. With respect to the infrared absorption spectrum of the barrier layer, the ratio of the maximum peak height (α) of absorbance within the range of 1,300-1,490 cm-1 to the maximum peak height (β) of absorbance within the range of 1,490-1,659 cm-1, namely (α)/(β) is 0.6 or more; and the ratio of the maximum peak height (β) to the maximum peak height (γ) of absorbance within the range of 1,660-1,750 cm-1, namely (β)/(γ) is 1.0 or more. The ammonia content per 100 cm2 is 2,000 μg or less.
