German equipment supplier Gneuss (U.S. office in Matthews, N.C.) last month received an unrestricted non-objection letter from the U.S. FDA covering the use of Gneuss’ MRS extrusion system for producing sheet from PET reclaim for food-contact applications. Introduced about four years ago, the MRS (multi-rotating system) is said to eliminate the need for drying or crystallizing PET bottle flake before processing. The machine features a 12D planetary-screw mixing section and is said to provide excellent devolatilization and gentle processing with a very low drop in resin I.V. Gneuss has sold more than 20 of these systems worldwide, including a half dozen in North America.
