In searching the Internet, I found that PVA and coplymers, e.g., poly (ethylene + vinyl alcohol) is sometimes layered between polyethylene. The PE+VA copolymer is a gaseous diffusion barrier, while the PE outer layers are moisture and chemically resistant.
It is possible that the makers of PVA sponges may have a modified PVA formula: http://www.ceibatech.com/AIONMain.htm

An internet search of "crosslink PVA" should provide other leads. Manufacturers of PVA emulsions may have some suggestions.
DuPont manufactures one type of product to crosslink PVA. http://www.dupont.com/tyzor/
Other suppliers: Kenrich or Johnson-Matthey catalysts businesses
