Abstract:

Multilayer foam-film composite structures in which the cells of at least one foam layer have an anisotropic orientation exhibit at least one enhanced property of toughness, tear resistance and puncture resistance in comparison with a foam-film composite structure alike in all aspects except for the anisotropic orientation of the cells of at least one foam layer.

US Classification:

428 365

Abstract:

Disclosed is an absorbent, extruded, open cell thermoplastic foam. The foam has an open cell content of about 50 percent or more and an average cell size of up to about 1. 5 millimeters. The foam is capable of absorbing a liquid at about 50 percent or more of its theoretical volume capacity when absorbing a liquid. The foam preferably has an average equivalent pore size of about 5 micrometers or more. The foam preferably has a structure substantially of cell walls and cell struts. Further disclosed is a method for absorbing a liquid employing the foam by elongation of the extrudate of the extrusion die. Further disclosed is a method of enhancing absorbency of an open cell foam by applying a surfactant to an exposed surface of the foam such that it remains at the surface and does not infiltrate a substantial distance into the foam. Further disclosed is a meat tray and a diaper containing the foam.
