177.1395 Laminate structures for use at temperatures between 120 F and 250 F.
（a The laminates identified in this section may be safely used at the specified temperatures. These articles are layered structures that are optionally bonded with adhesives. In these articles, the food-contact layer does not function as a barrier to migration of components from non-food-contact layers. The layers may be laminated, extruded, coextruded, or fused.
（b Laminate structures may be manufactured from:
? Polymers and adjuvants complying with 177.1390 of this chapter.
? Any polymeric resin listed in these regulations so long as the use of the resin in the structure complies with the conditions of use （food type and time/temperature specified in the regulation for that resin.
? Optional adjuvant substances used in accordance with 174.5 of this chapter.
? The following substances in non-food-contact layers only:
| Substances | Limitations |
| Ethylene/1,3-phenylene oxyethylene isophthalate/terephthalate copolymer (CAS Reg. No. 87365-98-8) complying with177.1345 | For use only with polyethylene terephthalate as the food-contact layer, complying with177.1630under conditions of use C through G described in table 2 of176.170(c)of this chapter. Laminate structures, when extracted with 8 percent ethanol at 150 F for 2 hours shall not yieldm-pheny lenedioxy-O,O-diethyl isophthalate or cyclic bis(ethylene isophthalate) in excess of 7.8 micrograms/square decimeter (0.5 microgram/square inch) of food-contact surface. |
| Nylon 6/12 resins complying with177.1500(b), item 13.2, of this chapter (CAS Reg. No. 25191-04-2) | For use with nonalcoholic foods at temperatures not to exceed 100 C (212 F). Laminate structures with authorized food-contact materials yield no more than 0.15 milligram ofepsilon-caprolactam and 0.04 milligram ofomega-laurolactam per square inch when extracted with water at 100 C (212 F) for 5 hours. |
| Nylon 6/66 resins complying with177.1500(b), item 4.2 of this chapter (CAS Reg. 24993-04-2) | For use only with:1. Nonalcoholic foods at temperatures not to exceed 82.2 C (180 F). Laminate structures with authorized food-contact materials yield no more than 0.15 milligram ofepsilon-caprolactam per square inch when extracted with water at 82.2 C (180 F) for 5 hours.2. Nonalcoholic foods at temperatures not to exceed 100 C (212 F). Laminate films with authorized food-contact materials yield no more than 0.15 milligram ofepsilon-caprolactam per square inch when extracted with water at 100 C (212 F) for 5 hours. |

| Nylon 6/69 resins complying with177.1500(b), item 14, of this chapter (CAS Reg. No. 51995-62-1) | For use with nonalcoholic foods under conditions of use B, C, D, E, F, G, and H described in table 2 of176.170of this chapter. Laminate structures with authorized food-contact materials may contain nylon 6/69 resins provided that the nitrogen content of aqueous extracts of a representative laminate (obtained at 100 C (212 F) for 8 hours) does not exceed 15 micrograms per square centimeter (100 micrograms per square inch). |
