Surlyn® Ionomer Resin

An Ionomer Resin Providing Clarity, Toughness, and Versatility

DuPont™ Surlyn® is a leading choice for food, cosmetic, medical device, and skin and stretch packaging— as well as in golf balls and industrial applications.

Known for its outstanding clarity, toughness, and light weight, DuPont™ Surlyn® ionomer resin is a reliable, cost-effective solution for a range of innovative packaging and other applications.

For food packaging, Surlyn® provides low-temperature seal initiation, excellent hot tack strength, and puncture resistance. It seals through contaminants, helps reduce leakers, and increases line speeds.

For cosmetics and medical device packaging, it provides clarity, formability, and scratch resistance. It is an attractive, lightweight alternative to clamshell and blister packaging.

Surlyn® is also used as the surface layer for golf balls, ski boots, and overmolded bottles. Its processing options include blown film, cast film, sheet, extrusion coating, and injection molding.

Surlyn® ionomer resin is available in a variety of grades, including some that help downgauge multi-layer structures and optimize material usage. Surlyn® also contributes to sustainability efforts by helping reduce waste by providing packaging integrity.
