Abstract

A packaging film includes a gas barrier film, an adhesive layer, and a sealant layer in this order. The gas barrier film includes a substrate layer, a vapor deposition layer, and a coating layer provided between the vapor deposition layer and the adhesive layer to cover the vapor deposition layer. The substrate layer includes a polyolefin substrate layer containing a polyolefin-based resin, and the coating layer has a hardness of 1.15 GPa or less measured in a cross section thereof using a nanoindentation method. The adhesive layer is obtained by bonding an adhesive resin composition containing a polyolefin adhesive resin to the gas barrier film by melt extrusion, and the sealant layer contains a polyolefin-based resin.
