Abstract
The invention discloses a manufacturing method for a tea bag folding structure comprising: a fold-to-overlap step and a press-to-fold step. The fold-to-overlap step is to overlap a sheet having a plurality of folding lines and join two opposite side edges thereof, and the press-to-fold step is to open the sheet into a hollow cylinder shape and fold the sheet into a cylindrical folding structure with openings at both ends along the plurality of folding lines. In the manufacturing method, after the tea bag folding structure is formed, one end opening of the tea bag folding structure is closed, the tea bag folding structure is filled with tea leaves, and the other end opening of the tea bag folding structure is closed.
