A rotomolded cooler, or rotational cooler, is a durable, high-end ice chest, which is made by the rotomolding process.
In production, the food-grade linear low-density polyethylene raw materials are first poured into the mold, and then the mold is heated and slowly rotated along two axes. Plastic raw materials will be uniformly attached to all corners of the inner wall of the mold to form a seamless box. This kind of shell has no seams and weak points, so it is durable and not easy to be damaged.
Finally, high-density polyurethane foam is injected into the hollow box body at high pressure, which not only further strengthens the box body but also makes the thermal insulation effect become particularly excellent.
