低温辐射电热膜是一种通电后能发热的半透明聚酯薄膜，由可导电的特制油墨、金属载流条经加工、热压在绝缘聚酯薄膜间制成。工作时以碳基油墨为发热体，将热量以辐射的形式送入空间，使人体得到温暖。
The low temperature radiation electrothermal film is a kind of translucent polyester film which can be heated after being electrified. It is made of conductive special ink and metal current carrying strip by processing and hot pressing between the insulating polyester films. When working with carbon based ink as the heating body, heat is sent into the space in the form of radiation, so that the human body gets warm.
