Surlyn resin shows a frosty flair for molded packaging

If you want a cool new packaging look, why not make it frosted? That’s a possibility with an innovative new application of DuPont Surlyn ionomer resins from DuPont Performance Materials (Wilmington, DE) suitable caps, bottles and jars for cosmetics using a one-step, straight-from-the-mold frosted effect. DuPont Surlyn frostedDuPont says the technique provides fine details, pleasing tactile quality and consistency without a need for a secondary process.

“Brand owners are constantly looking for new ways to differentiate their offerings, and a frosted effect is a unique decoration that creates a sense of premiumization in both look and feel,” says Jennifer Li, marketing leader – industrial & consumer, DuPont Performance Materials. “DuPont collaborates with industry partners to expand the possibilities of packaging design so that designers can create packages straight out of their imaginations.”

The unique properties of Surlyn enable it to copy fine, intricate details of a mold to achieve a high-gloss design with an entirely, or partially, frosted appearance. By applying this frosted effect in the mold, Surlyn offers increased production efficiency and lower cost for manufacturers looking to achieve this effect for their packages.Surlyn frosted lion

The frosted effect is a drop-in option with modest changes to the molding process.

“Some modifications are needed on the current molding processes for this,” Li informs PlasticsToday. “This is for injection molding only with the frosted effect obtained directly from the mold without a second step, thus providing great cost effectiveness.”

One would expect such a clever technique would be an ideal candidate for an equally clever name, but that’s not the case.

“There isn’t a branded name for this specific application or use,” Li responds, also pointing out that, among others, one ionomer candidate for the effect is Surlyn PC350.

The frosty option seems to have received a warm reception from the market. According to Li, “we have customers who are successfully using Surlyn for frosted parts in cream jars and fragrance caps.”

Polymer options for packaging and other markets are bundled together under one roof as part of the Advanced Design & Manufacturing (ADM) Expo Toronto that includes PLAST-EX, Automation Technology Expo (ATX), PACKEX, Design & Manufacturing and Powder & Bulk Solids (PBS) on May 16-18 in Canada.

Surlyn’s frosty appearance adds to the previous creative options for creative companies that include faceted or finishes to obtain special effects or colored pigmentation to create striking translucency. Surlyn allows the use of many different decorative techniques, including metallization, hot stamping, lacquering, marbling, bubbling, glittering and suspended animations. These options combine with Surlyn’s standard qualities of a warm, silky touch along with the functional benefits of toughness, high impact-resistance, abrasion resistance and excellent chemical resistance.
