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 cm 2 is 2,000 μg or less. |
