The present invention relates to a package body comprising a lid material, a container and contents,
the lid material consisting of a multilayer body having at least a base layer and a thermal adhesive layer,
the thermal adhesive layer being laminated as the outermost layer on one surface of the lid material, and hydrophobic oxide fine particles having an average primary particle diameter of 3 to 100 nm being attached to the outside surface where the thermal adhesive layer does not adjoin another layer, the hydrophobic oxide fine particles forming a porous layer having a three-dimensional network structure, and
the container being filled with contents, and sealed with the opening of the container in contact with the thermal adhesive layer of the lid material. |
