Patent ID: 8826844

Claim:
A method for producing a rotomolded article comprising: rotating an external skin layer composition, an intermediate foamed layer composition, and an internal skin layer composition in a mold to form an external skin layer comprising the external skin layer composition, an intermediate foamed layer comprising the intermediate foamed layer composition, and an internal skin layer comprising the internal skin layer composition; wherein the external skin layer composition comprises from 30 to 50 wt %, based on the weight of the external skin layer, of a resin composition and from 50 to 70 wt % of a metallocene-produced polyethylene, the same as, or different from that of the resin composition; wherein the intermediate foamed layer composition comprises from 95 to 99.8 wt %, based on the weight of the intermediate foamed layer, of the resin composition and from 0.2 to 5 wt % of a foaming agent; wherein the internal skin layer composition comprises a metallocene-produced polyethylene, the same as, or different from that used either in the external skin layer or in the resin composition; and wherein the resin composition comprises from 80 to 98 wt %, based on the weight of the resin composition, of metallocene-produced polyethylene, and from 0 to 20 wt % of grafted polyethylene and from 0 to 20 wt % of ionomer, with the restriction that at least one of the grafted polyethylene or the ionomer is not 0 wt %.
