Abstract:

A method for preparing a foam-layered packaging material, which method includes the steps of providing an outer shell having a bottom wall and upwardly extending side walls defining an interior space and having an open top; pouring onto the bottom wall of the outer shell a predetermined quantity of a mixture of polyurethane foam-forming reactants; covering the open top of the outer shell with an inner protecting and cushioning layer so as to define a confined space within outer shell; and allowing the mixture of polyurethane foam-forming reactants to foam and completely fill the confined space with polyurethane foam while at the same time forming a direct bond between the foam and the inner cushioning layer over substantially the entire surface of the inner cushioning layer facing the confined space; wherein the predetermined quantity of the polyurethane foam-forming reactants is an amount effective to substantially completely fill the confined space with polyurethane foam and bond the foam with substantially the entire surface of the inner cushioning layer facing the confined space without bleeding therethrough. Foam-layered packaging cases prepared by the method of the present invention are also disclosed.
