Abstract A method for fabricating a heat isolative paper container, which provides a paper board havin g a plu r ality of se a m s a t a circu mference thereof, and then a heat isolative mate rial con taining the hollow body is coated locally on at least a surface of the paper board and exempted from the seams. The container is then folded up as a con taine r, and the con tainer is heated, so that a heat isolative layer is provided on the surface of the container and has a heat isolative coefficient ranging from 0.003 to 0.05. The heat isolative material is made of polyurethane, PU, acrylic resin, polyethylene (P E), polypropylene (P P) po ly I a c t id e (P LA), a n d e p o x y. I n t h is manner, the heat isolative material con taining the hollow body may achieve the efficacies of a reduced volume, a red uced transportation cost, and an improved he at iso I ative e ffe ct, by using an isolative layer containing a hollow body. 22, |
