PURPOSE: A frame for a plastic greenhouse is provided to insert a nonwoven fabric and a plastic sheet into a mounting member at the same time after overlapping, without using a separate wooden lath, a nail, or a screw. CONSTITUTION: A frame (A) includes a supporting member (10) formed by producing a web unit piece (102) through bending both ends of a flange piece (101). A mounting member (11) is formed on the front inside of the web unit piece. A hanging piece (103) is formed on the mounting member by bending the end of the web unit piece. Each end of the web unit piece is bent by facing each other to form a flange member (105). A nonwoven fabric (20) and a plastic sheet (30) are inserted in between the supporting member and the mounting member using an elastic expansion unit (40).
