Abstract:
The purpose of the present invention is to achieve both cutting and heat-sealing by means of a laser and provide a method for manufacturing a tea bag (30) having high manufacturing efficiency or a tea bag (30) that controls against outflow of contents thereof. The method for manufacturing the tea bag (30) involves: a temporary affixing step wherein two filter sheets (10a, 10b) are stacked and temporarily affixed so as to define a prescribed outer shape; and a shaping step wherein a laser is used to cut and heat-seal the area at most 2mm outside the temporary affixing position (20) of the two filter sheets (10a, 10b).
