Abstract: The present invention relates to a method for manufacturing a paper straw, the method comprising: a paper roll transmission step, a paper strip heating step, a bonding and shaping step and a cutting step. Wherein, a plurality of raw paper rolls face a connection position jointly to transmit a raw paper strip, the raw paper strip includes a paper material and a dry hot-melt adhesive. The dry hot-melt adhesive of the raw paper rolls is heated for changing into flow hot-melt adhesive. Then the raw paper rolls is transmitted to the connection position for rolling jointly, and the flow hot-melt adhesives are bounded on another raw paper strip to form a pipe. Finally, the pipe is cut to form at least one paper straw after the pipe exceeds a setting length.

Abstract: The present invention relates to a paper material for producing a paper straw mainly, the paper material includes: a paper and a hot-melt adhesive material; wherein, the hot-melt adhesive material is provided on at least one surface of the paper, including an acrylic acid copolymer 40%˜45% w/w, an ammonia water less than 0.1% w/w or equal to 0.1% w/w and a water 55%˜60%. w/w The hot-melt adhesive material is presented as a dry hot-melt adhesive without viscosity and being transformed to a flow hot-melt adhesive with viscosity while being heated from 80° C.˜200° C.
