Abstract
An air-permeable packaging material for an oxygen scavenger includes, in this order, an outer layer containing a thermoplastic resin, an intermediate layer containing one or more selected from paper and nonwoven fabric, and an inner layer containing a linear low-density polyethylene, the inner layer includes a through-hole H1, the through-hole H1 having an opening diameter φ1 of 150 µm or more and 3000 µm or less, and when differential scanning calorimetry is performed using the inner layer as a measurement sample in a nitrogen atmosphere under conditions of heating from 50°C to 200°C at 10°C per minute (heating 1), then cooling from 200°C to 50°C at 10°C per minute (cooling 1), and heating again from 50°C to 200°C at 10°C per minute (heating 2), a maximum endothermic peak is observed at 120°C or more in a process of (heating 2).
