Abstract: A plastic corrugated folding container is provided wherein box body assembly can be performed without catching of the latch side panels on column members, the four corners of the box body can be closed tightly, and during folding, lid members, partitioning panels, or similar can be stored. A heating bar set to a prescribed temperature is applied to folding lines of a floor panel, and side panels and latch side panels thereby rise up due to heating and melting. A heating bar set to a prescribed temperature is applied to folding lines in the lower parts of a pair of second side panels, and an engaging piece is bent outwards by heating and melting; an engaging piece of the second side panel is configured to engage with an engaging hole in the latch side panel, and a box body having a floor that does not sag can be provided.
