The US Food and Drug Administration has granted approval to thermoplastic elastomers for food contact applications. This approval gives flexibility, greater simplicity for packaging manufacturers and range of options to packagers regarding food packaging materials.
The TPEs granted approval include:
GLS's Dynaflex G2700 : extends the material's use for contact with fatty as well as non-fatty foods.
The Dynaflex G2700 series of thermoplastic elastomer compounds are designed for injection molding and extrusion applications that require FDA compliance, claims GLS. The material is available in a hardness range from 28 to 64 Shore A, has a soft touch, rubbery feel and excellent colorability. 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.
