Abstract: A leaf filter bag for a leaf (110) of a pressure leaf filter (100) has a first sheet portion (50), adjacent to a second sheet portion (60). The first sheet portion (50) is connected to the second sheet portion (60) at a first edge (10), a second edge (20) and a third edge (30). Forth edges of the sheet portions define an openable and closable edge (40) which has an open position and a closed position, which allows inserting a frame (122) of the leaf (110) into the leaf filter bag (1) through an opening formed by the openable and closable edge (40) in the open position. A zipper (42) closure (41) is provided at the openable and closable edge (40), and a further hook-and-loop fastener closure may be provided.
