Medical dry film is a specialized imaging medium that requires no chemical processing and produces medical images directly via thermographic or laser‑based imaging technologies. It is primarily used for recording images from X‑ray, CT, MRI, and other medical imaging modalities.

Medical dry film is a specialized type of imaging film that requires no chemical processing; instead, it directly produces medical images through thermographic or laser‑based imaging technologies. It is primarily used for recording images from X‑ray, CT, MRI, and other medical imaging modalities. Its defining feature is dry imaging, which eliminates the chemical development process associated with traditional wet‑process films [14]. According to the industry standard YY/T 1796‑2021, medical dry films include thermal‑sensitive films composed of a polyester (PET) base coated with silver halide and a protective layer, as well as infrared laser‑sensitive films; additionally, there are thermographic films consisting of a polyester (PET) base, a thermosensitive layer, and a protective layer [11].
China’s medical dry‑film market was long dominated by foreign companies. Over the past decade, domestic firms—led by Collier—have achieved significant breakthroughs in this field. In 2012, Collier’s independently developed non‑silver‑based dry film won the “Medical Imaging Film Innovation Award.” In 2017, Collier launched a project to develop its own thermosensitive dry film. As a result, the price of domestically produced medical dry films has been brought down, and by 2022, Collier had begun to play a role in regional smart‑healthcare initiatives [1]. In 2023, Lekai Film reported a 22% year‑on‑year increase in sales of medical dry films, further expanding its market share [6].
