Thermoplastic Polymer Chosen for Packaging

Clear copolyester material used in a dental-tool box. The Swiss company Bien-Air SA has selected Eastar copolyester as its new dental-package material. Eastar is manufactured by Eastman Chemical Co. (Kingsport, TN; 423/229-1424); it will be used to create the dental kit's housing, lid, and several separation inserts and clips. The material, a thermoplastic polymer, displays clarity, chemical resistance, and mechanical strength. Bien-Air reportedly chose the material for its attractive product-display properties, its high flexibility, its dimensional stability, and its stress-crack resistance. Eastar copolyester can also be recycled. Additionally, the material complies with biocompatibility requirements set forth by FDA and ISO.
