  The present invention relates to a method for adhering a plastic band to a paper cup, and more particularly, a safe paper cup without a concern about health problems caused by chemicals by adhering a vinyl band to one end of the paper cup. The present invention relates to a method for adhering a vinyl strip to a paper cup paper.

For paper cups, roll paper rolls that are generally cut into wide, narrow and narrow shapes, and paste the overlapping parts of both ends into a tapered tube shape, then attach the bottom to the inside of the lower portion of the tapered tube shape. Will be produced.
Conventionally, paper cups have been rolled up in a round shape, and an adhesive is applied to the overlapping portion to bond them. However, various problems due to the use of the adhesive have been pointed out. In other words, the adhesive is a chemical, which may impair the health of the worker due to the odor peculiar to the chemical, and touches the user's mouth after the adhesive on the paper has hardened, and has an unpleasant odor. There was a problem that worried about the health of the user.

  With regard to the bonding between the end portions of the paper cups, the inner surface of one end face and the inner surface of the other end face each other so that one end edge protrudes from the other end edge. A method in which the ends of the body member blanks are joined to each other by a method in which the ends of the body member blanks are overlapped with each other so that the other end edge is hidden. The end face of the body member blank on the inner surface of the joint portion is covered when heated using a specific tape material composed of a center layer and a coating layer, and the coating layer is made of a resin having the same thermal adhesive properties as the paper cup. There have been proposals such as an adhesive method (see Patent Document 2) in which the layer flows and the end face portion of the tape material is not exposed.
