Benefits Gained

Cost savings. Elvax® costs less than alternative compounded liner materials.

Tight sealing. Because Elvax® has good water vapor and gas barrier properties as well as resiliency, liners seal containers tightly.

No "neck ring". Unlike compounded liner materials, Elvax® contains no mineral oil, which can mix with the soft drink and cause deposit of a ring of unsightly brown residue on the inside of the bottle's neck.

Materials Selected and Why

For extruded liner stock and compression molded liners, Elvax® 760Q and 650Q provide the right level of melt index, adhesion, resiliency, barrier, balanced sealing characteristics, removal torque and minimal taste.
