Abstract:
A non-perfluoro fluorine-containing resin molded article having a surface layer; a part of the surface layer comprises a surface layer portion having a low temperature heat scaling property; said surface layer portion having a low temperature heat-sealing property has a ratio F/C of the number of fluorine atoms to the number of carbon atoms of 0.2&lE;F/C&lE;0.9 and a ratio O/C of the number of oxygen atoms to the number of carbon atoms of 0.09&lE;O/C&lE;0.40, and a remaining part of the surface layer has a ratio F/C of the number of fluorine atoms to the number of carbon atoms which is larger than that of the surface layer portion having a low temperature heat-sealing property and is 0.8&lE;F/C&lE;1.8.
