Abstract
A method for sealing a retort container comprises the steps of heat-sealing an opening of a retort container after charging contents into the container so that a line-seal having a width ranging from 0.5 to 2.5 mm is formed to thus seal the container and then performing knurled sealing at a portion including the line-seal. The sealing method can provide a container having sufficient seal strength and does not spoil the beautiful appearance of the flange portion of the container even if contents thereof remain in the flanged portion or the like. Moreover, the method does not cause foaming in the sealed regions at all and it is not necessary to perform the sealing treatment under substantially severe conditions to prevent the occurrence of the foaming and, therefore, the method can provide containers having a sealed portion easily peelable.
