Method for manufacturing paper buffer tray for packaging and buffer tray manufactured thereby

A method for manufacturing a paper buffer tray for packaging, comprising:

• a raw material preparing step of preparing a raw material by laminating a plurality of sheets of papers;
• a molding preparing step of preparing at least one mold corresponding to a shape and size of a product to be packaged;
• and
• a molding step of press-molding the raw material by using the at least one mold,
• wherein the raw material is prepared by attaching and laminating two or more inner sheets of paper and at least one outer sheet of paper by an adhesive,
• wherein the two or more inner sheets of paper are cut in a length direction around a center portion of the shape of the product to be packaged,
• wherein the molding preparing step comprises preparing at least two separate molds to apply to different parts of the raw material, and a spring is mounted to one mold of the at least two separate molds to control a timing when the one mold contacts the raw material, the spring being not mounted to other molds of the at least two separate molds,
• wherein the two or more inner sheets of paper are alternately cut in a zigzag form alternately in both sides along the length direction, and alternating cut surfaces of the two or more inner sheets of paper overlap each other in opposite directions such that valleys and peaks of each cut shape intersect with each other, and
• wherein the adhesive includes starch.
