The invention relates to a method for producing multilayer composite plastic storage pot, which comprises: putting different plastics or same plastic with different diameters into mould; in the rotation and heating of mould, fusing it into multilayer composites plastic storage pot. The invention has utilize the different fusion temperatures of different plastics, to composite mold, or uses the different particle size of same plastic that different heat adsorption speeds. The invention has improved anti-age property. |
