Abstract

See full text

The present invention relates to an improved packaging composition comprising an ethylene copolymer selected from ethylene acid or ester copolymers such as ethylene vinyl acetate, ethylene/acrylic acid or methacrylic acid copolymers which optionally contain a third comonomer such as an alkyl acrylate and the corresponding ionomers of said copolymers which are blended with a hydrophilic zeolite to form a composition which removes residual acids or small esters from the polymeric or ionomeric composition containing such residual acids. The acids may be present as initial by products in the copolymerization process or may be degradation products. The use of these compositions is particularly important when the resins are formed into packages or other fabricated material which are exposed to acid sensitive material.
