The invention comprises a peelable membrane for resealably closing a metal end comprising an outer layer, a tacky layer, and a heat seal layer. The heat seal layer is permanently sealed to the metal end to cover at least one opening in the metal end. The tacky layer causes the peelable membrane to be resealable onto the metal end.

Provided is an ionomer resin composition comprising a sodium-neutralized ethylene acid dipolymer and a sodium-neutralized ethylene acid ester terpolymer, wherein desirably at least one of the dipolymer and terpolymer is in part a recycle material. The described ionomer composition is particularly suited for use in making interlayers and glass laminates comprising such interlayers.
