A film 10 capable of emitting far-infrared rays comprises a surface layer 20 and a carbonic layer 30 coating the surface layer 20 and having carbon of at least 60wt%. Preferably, the carbonic layer 30 is made of at least one material selected from the group consisting of bamboo charcoal powders, carbon fibres, carbon nanotubes, activated carbon powders, activated carbon grains and activated carbon fibres. The carbonic layer 30 may be a fabric, nonwoven, a paper having vents or a membrane. The carbonic layer 30 may further comprise an artificial fibre of at most 40wt% or a metal of at most 2wt% in the shape of metallic particles or membrane wherein the metal is selected from the group including silver, gold, palladium, copper, zinc, aluminium and chromium. Preferably the surface layer 20 is made from natural fibre, artificial fibre, polymer, natural leather, artificial leather or a combination thereof. The film 10 may be useful in emitting far-infrared rays to heighten the temperature of human skin, increase blood circulation and enhance the absorbability of active ingredients to the skin. The film 10 may also be useful in protecting the skin against ultraviolet rays.
