SURLYN™ Ionomers

Are your packaging applications in good shape? 

Good looks. Great qualities. Versatility. SURLYN™ Ionomers are a great fit for many packaging applications. SURLYN™ Ionomers are ethylene acid copolymers that have been partially neutralized. Most of the mechanical properties of SURLYN™ Ionomers are directly related to its acid content and level of neutralization. Our complete family of SURLYN™ Ionomers cover a relatively large viscosity domain to fit most processing requirements.

Doing more with less material

Consumers want packaging that uses less while doing more. SURLYN™ Ionomer Resins can allow for downgauging, while maintaining performance attributes such as stiffness, formability, puncture and abrasion resistance, excellent sealing, and high clarity. To ensure quality is not compromised, we developed capabilities to model the stiffness of packaging structures containing up to nine layers. Modeling has shown that films based on SURLYN™ Ionomers can maintain overall stiffness despite considerable downgauging.

Introducing circular and bio-based grades

We recently launched two extensions of the SURLYN™ Ionomers family that pioneer the use of bio-based and circular feedstocks. SURLYN™ REN and SURLYN™ CIR Ionomers will enable beauty brands and manufacturers to create high-quality cosmetic packaging that stands out on the shelves and offers enhanced sustainability.

Flexible packaging for today and tomorrow

SURLYN™ Ionomers have long been a go-to option for flexible packaging formats such as sachets, pillow pouches, flow-wrap packages, vacuum skin packaging, composite cans and stand-up pouches. SURLYN™ Ionomers are used in a wide variety of food and non-food packaging, as well as pharma and medical packaging applications.

Excellent sealing

Compatible with a very broad sealing temperature range, including low sealing temperature, as well as outstanding seal through contamination and excellent hot tack strength.

Optimal resistance

Offering abrasion, puncture and scratch resistance, as well as excellent oil and grease resistance.

High clarity

Achieve very high clarity and gloss for see-through films.

Superb thermoformability

High shrink rate and low shrink force means a tight draw around the package while maintaining the original shape of even the most delicate products.

High-gloss appeal for rigid packaging innovations

SURLYN™ Ionomers support rigid packaging applications with durability and optical benefits—particularly products requiring a higher-end look and feel.

For cosmetic packaging, injection molded structures made with SURLYN™ Ionomers feature scratch resistance, chemical resistance and excellent aesthetics for a distinctive, high-performance design.

Rigid containers benefit from strong impact resistance and an almost mirror-like high-gloss appeal. Those containers can stretch the imagination for uses—from hair care and other personal care items to a variety of beverages, spirits and liquors.

Stretch Pak: A blister packaging alternative that is kinder to the environment

The industry required an alternative to blister packaging that was better for the environment but didn’t sacrifice performance. Because the contents are important, toughness and formability were crucial. We also needed to reduce weight, volume, and overall material, leading to lower source material usage. So, we turned to SURLYN™ Ionomer resins, a material that enables skin and stretch packaging film with reduced material usage, enhanced shelf appeal and great performance.

Stretch Pak films made with SURLYN™ offer significant advantages over conventional blister, fold-over blister, and clamshell packaging:

Permits fast throughput and line speeds for easier processing at higher packaging yields. SURLYN™ absorbs infrared heat at about twice the rate of polyethylene. Its ability to soften more quickly in the heating phase speeds up the whole packaging process, allowing around 40% more packaging cycles in the same time frame.
Products can be packaged in single or multiple units without interfering with production.
