Method for Fabricating A Heat Isolative Paper Container

Abstract

A method for fabricating a heat isolative paper container, which provides a paper board having a plurality of seams at a circumference thereof, and then a heat isolative material containing 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 container, and the container 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 (PE), polypropylene (PP), polylactide (PLA), and epoxy. In this manner, the heat isolative material containing the hollow body may achieve the efficacies of a reduced volume, a reduced transportation cost, and an improved heat isolative effect, by using an isolative layer containing a hollow body.
