New material approval provides packagers with a greater range of options that can be made in deciding which material can be used to contain food products. The approval of GLS's Dynaflex G2700, which is made from Kraton polymers, extends the material's use for contact with fatty as well as non-fatty foods. Walter Ripple, director of sales and marketing for GLS said the primary benefit is that packagers can use a single family of TPE compounds for all of their container requirements. "No other competitive materials can make this claim for a full line of grades. This means one-stop shopping and greater simplicity for packaging manufacturers," he said. The Dynaflex G2700 series of thermoplastic elastomer compounds are designed for injection molding and extrusion applications that require FDA compliance, claims GLS. Available in a hardness range from 28 to 64 Shore A, they feature a soft touch, rubbery feel and excellent colorability, the company claims. Dynaflex also offers good melt stability, high flow for long, thin-wall parts, good adhesion to polypropylene, and good ozone and UV resistance, GLS claims. Depending on the grade, they are available in either natural or clear pellets. Drying is not required. Regrind levels of up to 20 percent can be used with minimal property loss, provided the regrind is free of contamination. Illinois-based GLS, is a global manufacturer and supplier of application-specific, custom formulated soft and ultra-soft TPEs for injection molding and extrusion.
