Definitions

  • Molding strain due to the manufacturing method remains in the ordinary heat-meltable fluororesin film.
  • the film of the present invention has a thermal expansion / contraction rate of -1 to + 1% for both MD and TD by appropriately controlling the cooling conditions of the resin film during molding, with little distortion in each direction and sufficiently uniform.
  • haze is 8% or less even when the thickness is 100 to 200 ⁇ m, and the transparency is excellent. Therefore, even in the laminated body having such a film layer, it is considered that the strain is small and the film is sufficiently uniform, so that the thermal shock resistance is excellent, the deformation is suppressed, and the dimensional stability is excellent.
