ABSTRACT:
The present invention provides with a shaped article of a fluorocarbon polymer having a fluorine/carbon ratio of 1.9 to 2.0, in which at least a part of surface has a fluorine/carbon ratio of 0.8 to 1.8. The shaped article has an improved adhesive properties, especially heat-sealing adhesive property and can be manufactured by a low-temperature plasma treatment of the surface of the fluorocarbon polymer shaped article.
As compared with conventional surface-reformed ones, the fluorocarbon polymer shaped article of this invention has an improved adhesive property, especially for heat-sealing, which is not deteriorated during their storage either at a high temperature, at a high humidity or on exposure to ultraviolet ray.
