Section 175.105 does not include any temperature limitations. However, in the FDA Guidance Preparation of Premarket Submissions for Food Contact Substances: Chemistry Recommendations, 2007, the section on adhesives includes a temperature restriction. The guidance outlines that for adhesives used at room temperature or below, “If the adhesive is either separated from food by a functional barrier, or the quantity of adhesive that contacts aqueous and fatty food is limited to the trace amount at seams and edges, then migration levels for the substances generally will be assumed to be no greater than 50 ppb.” The Chemistry Guideadds that the migration protocol corresponds to Condition of Use E, which is for packaging material that is room temperature filled and stored, and does not undergo thermal treatment.
