Abstract
A molded product is made comprising a low-density product having an impermeable surface. The impermeable surface integral with the low density interior is suitable for receiving various types of brightly colored finishes. It is also contemplated that a non-porous plastic film may be molded in place on the surface of the molded product.
Claims5
A low-density product having a non-uniform cross-section and a sealed impermeable surface, said product and its surface both having been formed from the same sheet of pliable polyethylene based foam material of substantially uniform cross-section.
A low-density product formed of pliable polyethylene having a non-uniform cross-section, a smooth impermeable surface, and a compressible foam interior integral with said impermeable surface.
A low-density product formed of a single section of compressible polyethylene or ethylene vinyl acetate copolymer foam having a relatively low density interior and a relatively higher density outer surface surrounding said low density interior and integrally formed therewith, said higher density outer surface being substantially impermeable to liquids, said product having been formed into an irregular shape having variable vertical, lateral, and horizontal cross sections.
