Abstract

A method of sealing a container and a lid by melt adhesion by laser. Either the container or the lid has a thermoplastic resin that permits the laser beam to transmit through and the other one has a resin composition of the thermoplastic resin containing a heat-generating substance. Further, the laser beam applies a rectangular beam having a uniform intensity distribution. The upper-limit of temperature is not lower than a melting point of the thermoplastic resin but lower than a thermal decomposition start temperature thereof in the melt adhesion interface between the container and the lid, and the temperature reaches the upper-limit in a heating time t (msec) represented by the following formula (1),(msec)=  (1)where L is the length (mm) of the rectangular beam in the scanning direction, and S is the rate of laser scanning (mm/msec) of not higher than 1.65 mm/msec.
