Abstract: A film forming composition comprises a film forming component and a solvent, wherein the film forming component comprises 0-50 wt % of a first water soluble polymer, 0.3-40 wt % of a second water soluble polymer, 0-15 wt % of plasticizer and 50-70 wt % of active ingredient. The first and second water soluble polymers have a Tg of −52° C. to 216° C., and difference of Tg values of the first and second water soluble polymer is 62-268° C. The film formed by the film forming composition capable to load high content of active ingredient and lead to fast absorption of active ingredient is provided.
