    摘要： A multi-layer article including a foodware substrate and a fluoropolymer composition having a copolymer consisting of from 80 to 94% by weight tetrafluoroethylene, from 6 to 20% by weight of one or more perfluorovinyl ethers of the formula CF2═CFO(RafO)n(RbfO)mRcf, where Raf and Rbf are independently selected from linear or branched perfluoroalkylene groups of 1-6 carbon atoms, m and n are each independently 0-10 and Rcf is a perfluoroalkyl group of 1-6 carbon atoms, where when the perfluorovinyl ether content is less than 7% by weight, the fluoropolymer has an MFI of 5 or less; and/or a copolymer comprising from 80-94% by weight tetrafluoroethylene, from 5-20% by weight of a perfluorovinyl ether of the formula CF2═CFO(RafO)n(RbfO)mRcf where Raf, Rbf, m, n and Rcf are the same as defined above, and up to 15% by weight of one or more additional monomers based on the total weight of the fluoropolymer.
