摘要

To provide a packaging material unlikely to cause printing omission, with light transmittance of 0.001% or less, capable of increasing a whiteness degree, and capable of coping with materials needing a high protective performance such as a content for a medical use or a food product where light-shielding properties and a barrier layer are required, and also to provide a light-shielding barrier bag using the same, an outer packaging bag for an infusion bag and an infusion bag unit.SOLUTION: There is provided a packaging material including a substrate layer, a first laminate layer, a barrier layer, a second laminate layer and a sealant layer, sequentially. The sealant layer contains carbon black of 1-20 wt.% and a titanium oxide of 1-30 wt.%.SELECTED DRAWING: Figure 1
