Intended Use: As an adhesive in laminate structures for use at high temperatures, including microwave reheating, except for use in contact with infant formula and human milk (see Limitations/Specifications).
Limitations/Specifications: The adhesive may be applied at a maximum rate of 2.5 pounds per 3000 square feet of food-contact surface. A food-contact layer will separate the adhesive from food and will consist of low density polyethylene with a minimum thickness of 1 mil or another material with equivalent or greater barrier properties under the intended conditions of use. Laminate structures using the FCS as an adhesive may be used in contact with all food types under Conditions of Use B through H as described in Tables 1 and 2. The FCS is not for use in contact with infant formula and human milk. Such uses were not included as part of the intended use of the substance in the FCN.
