A container comprises a first and second wall parts to be heat bonded together along respective sealing portions from thermoplastic resin layers having a polyethylene chain, at least one wall part being a laminated structure comprising a thermoplastic resin inner wall layer with a plurality of minute holes and a paper outer wall layer which is permeable to gases but is impervious to microorganisms, at least one thermoplastic layer of a sealing portion, prior to being heat bonded, being irradiated with ionizing radiation rays to introduce thereinto a crosslinked structure. By seal packaging a medical supply commodity with this container and sterilizing the same with a gas or steam, a readily unsealable, sealed package can be produced for ready use at any time and place.
