Ticona Introduces Lower-Cost Topas® COC Grade for Flexible Packaging

Ticona (www.ticona.com), the engineering polymers business of Celanese Corporation, has introduced a new, more cost-effective grade of Topas® COC (cyclic olefin copolymer) for packaging applications. This second-generation COC, Topas 8007F-100, provides a broad processing window and an excellent cost-performance ratio as a blending component in polyethylene-based packaging films to add stiffness, thermoformability, controlled tear, improved sealing and antiblock characteristics.

Topas 8007F-100 provides the same basic properties as other Topas grades at lower cost. Although its optical properties are not at the same ultimate level as other Topas packaging grades, they have proven satisfactory in many applications in which Topas 8007F-100 was blended with a wide range of polyolefins. Best results have been achieved with LLDPE (including metallocene and plastomer LLDPEs), LDPE, HDPE and blends of these polymers.

“With Topas 8007F-100, we are targeting cost-sensitive packaging applications using COC blended into polyethylene as a performance enhancer,” says Bernd Sparenberg, Global Marketing Manager. “In most cases, COC is used as a minor component at a concentration of 10 to 20 percent to customize overall film properties in applications such as pouches, forming webs and coated paper.”

Topas 8007F-100 complies with US and EU food contact regulations and has been evaluated in numerous commercial programs. Positive customer feedback received in these programs paved the way for the introduction of Topas 8007F-100 into the flexible packaging market.
