Abstract: A novel technique to treat post-consumer polyester for reuse in food-contact applications is described. The process comprises contacting contaminated post-consumer polyester flake with at least one extraction solvent which is soluble in said contaminated flake at a temperature sufficient to allow rapid diffusion of contaminants from said polyester flake; and removing said extraction solvent containing said contaminants from said polyester flake.

Abstract translation: 描述了一种将消费后聚酯用于食品接触应用中的再利用的新技术。 该方法包括将受污染的消费后聚酯薄片与至少一种可溶于所述污染的薄片的提取溶剂接触，所述提取溶剂的温度足以允许来自所述聚酯薄片的污染物的快速扩散; 并从所述聚酯薄片中除去含有所述污染物的所述提取溶剂。
