The synthetic-resin coated aluminum foils of the front and rear sides of the packer body are thermally-bonded to form an inner space. The inner space of the packer body is divided into two areas by an inner partition line(22), which is formed by the thermal bonding. The first foaming agent and the second foaming agent are respectively filled in the two areas of the inner space of the packer body. The first and second foaming agents are mixed and form a foaming body.;COPYRIGHT KIPO 2011
