Description

Technical Field

[0001] The utility model relates to the technical field of oral fast-dissolving films, in particular to a glue filter for producing oral fast-dissolving films. Background Art

[0002] Oral fast-dissolving film, also known as oral dissolving film, oral dispersible film, oral fast-dissolving film, oral fast-dissolving film, is a new drug delivery system, which refers to a film-like preparation made by processing drugs and suitable film-forming materials for oral or mucosal use. Its size, shape and thickness are similar to stamps. When placed on the tongue, it can quickly dissolve in saliva and release drugs without drinking water.

[0003] In the production process of oral fast-dissolving film, the glue liquid needs to be filtered to separate and filter the white spots and the polyvinyl alcohol that is not completely dissolved in the glue liquid. The existing methods of filtering the glue liquid mostly use a single filter plate to filter the glue liquid. The filtration speed of the glue liquid is slow, and after a long time of filtration, the filter plate is easily blocked, and the subsequent glue liquid cannot be filtered, which is inconvenient for the staff to use. Therefore, we propose a glue liquid filter for the production of oral fast-dissolving film. Utility Model Content
