Abstract

The main objective of this invention is to provide a rubber molded article having a non-fluorinated resin film layer on its surface, and the rubber molded article exhibits good gas barrier properties and electron beam resistance, as well as good formability during manufacturing. This invention provides a rubber molded article comprising a non-fluorinated resin film layer; in the non-fluorinated resin film before lamination, the ratio of elongation in the TD direction to elongation in the MD direction (TD / MD) is 0.80 or more to 1.20 or less. Furthermore, in the non-fluorinated resin film before lamination, the elongation in the MD direction may be 150% or more to 450% or less, and the elongation in the TD direction may be 150% or more to 450% or less.
