Eastman Eastalite to Be Showcased at MD&M West 2014

Eastman Chemical Co. will highlight medical packaging at the upcoming Medical Design & Manufacturing (MD&M) West exhibition (Feb. 11-13), including Eastalite copolyester, the company’s first opaque offering. The material joins Eastman's line up of medical packaging copolyester offerings such as Eastman Eastar 6763 and Tritan MP100.

Eastalite is presented as an alternative to high-impact polystyrene (HIPS) for opaque rigid medical packaging. It can be used for applications in which lightweighting and other sustainable attributes are part of their fitness for use requirements, including work-in-progress trays, thermoformed pharmaceutical packaging and packaging for economical medical devices or kits, Eastman reported in a press release.

“This new opaque material is another demonstration of Eastman’s commitment to providing innovative, cost-effective and sustainable solutions to meet the needs of the medical packaging industry,” explained Aneta Clark, market development representative for medical packaging, Advanced Materials-Specialty Plastics, Eastman Chemical Company, in the release. “Eastman Eastalite copolyester provides brand owners and medical device manufacturers with a material at a price comparable to HIPS, but one that is free of styrene and easier to process.”

According to Eastman, using Eastalite copolyester in rigid trays can reduce processing and inspection time, waste and cleaning, as well as processing costs. It also has the potential to reduce cycle times as compared with HIPS, due to minimal particulate or angel hair generation and reduced risk of black specks, it was reported. Extruded Eastalite contains a foam core with a contact surface skin of Eastman Eastar copolyester 6763.

Packaging made with Eastman Eastalite copolyester can be designed with deep undercuts, resulting in better hinge life and less stress whitening than packaging molded from HIPS, the company reported. The copolyester offers tear strength, as alternative materials are brittle and crack-susceptible, it was reported. 

"Although sheet extruded from Eastalite can be processed with the same thermoforming, trimming and sealing equipment as HIPS, its lower process temperatures offer greater opportunities for sustainable packaging," Eastman reports in the press release. The material is made without materials of concern, including butadiene, bisphenol A, bisphenol S, ortho-phthalates, polyvinyl chloride or halogens such as chlorine or bromine. The material is compliant with select ISO 10993 requirements for medical device biocompatibility.

"Eastman Eastalite copolyester can create new market opportunities by providing brand owners and medical device manufacturers with a material to produce differentiated products that satisfy the unmet market need,” added Clark. “Eastman strives for sustainable innovation by creating solutions that offer more value with less environmental impact.”
