▎ 摘  要

NOVELTY - Anti-fog cleaning heat-shrinkable film comprises 50-80 pts. wt. safety heat-shrinkable structural resin, 10-30 pts. wt. safety water-absorbing resin, 1-10 pts. wt. safety edible anti-fog surface active material and 0.1-1 pts. wt. safety barrier nano material. USE - The film is useful in scene e.g. medical endoscope, glasses, automobile glass, optical device or greenhouse material, preferably medical endoscope including laparoscope, choledochoscope, gastroscope, enteroscope, cystoscope, laryngoscope, bronchoscope and/or thoracoscope. ADVANTAGE - The film has high safety and durability and is easy to clean. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing anti-fog cleaning heat-shrinkable film comprising mixing the safety heat-shrinkable structural resin, safety water-absorbing resin, safety edible anti-fog surface active material and safety barrier nano-material, extruding and blowing to obtain the anti-fog cleaning heat-shrinkable film.
