摘要

PROBLEM TO BE SOLVED: To provide an inexpensive package container to be heated in microwave oven for which a vent hole is automatically formed when heating is made in a microwave oven. SOLUTION: For a package container to be heated in microwave oven made up of a laminated film comprising a thermoplastic film layer and a heat-sealable resin layer, a microwave-absorbing layer in a thickness of 1 to 8μm consisting of an ink made up by scattering nonmetallic microwave-absorbing particles in a nonmetallic resin is formed in a specified shape at a part at the inside of the thermoplastic film layer.
