The molded film 1000 according to the present invention may be manufactured as shown in FIGS. 6 and 7 through the film processing apparatus 10 described above. The configuration of the molded film 1000 will be described in more detail as follows.

The molded film 1000 according to the present invention includes film paper having a predetermined area, a first sealing area 1100 formed on the film paper, a second sealing area 1200, and a perforated line 1300.

The film sheet has a predetermined area, and both ends of a pair facing each other are open, and a pair of ends adjacent thereto are closed. The area of such film paper may be manufactured in various shapes and ratios in consideration of the usage mode.

The second sealing area 1200 is formed at one end of the open film sheet and closes the open end to form a closed end of the forming film 1000 . The second sealing area 1200 forms the second sealing area 1200 to form a closed end by sealing one end of the opened end as a whole to cross both closed ends of the film paper and closing either end of the opened end. do. The second sealing area may be formed through any method as long as the open end of the film paper can be stably sealed, but it is preferable to form the second sealing area 1200 through thermal fusion.

The first sealing area 1100 is formed to be inclined at a predetermined angle with the second sealing area 1200 at the corner of the film paper on which the second sealing area 1200 is formed. At this time, the first sealing area 1100 is formed at both corners of the film paper so as to cross the sealed end 1400 of the film paper and both ends adjacent to the sealed end 1400 as a whole at a predetermined angle. The inclination angle and formation position of the first sealing area 1100 may be determined in consideration of the usage mode of the molded film 1000 to be used. At this time, it is preferable that the formation angle of the first sealing area 1100 be parallel to an arbitrary imaginary line crossing the edge of the film paper. Since this first sealing area 1100 has a great influence on forming the upper end when the molding film 1000 is unfolded as shown in FIG. 7, considering the area of the upper end of the unfolded molding film 1000, the corresponding position and angle It is good to be formed as

The perforation line 1300 is formed on one side adjacent to the first sealing area 1100 so that the user can easily remove the outer portion of the perforation line 1300 according to usage conditions. These perforated lines 1300 are formed to be spaced apart from one side adjacent to the first sealing area 1100, preferably, to the outside of the first sealing area 1100 at a predetermined interval, and the interval forming the perforated line 1300 is determined by the material of the film paper and It may be formed at intervals that a user can easily cut along the perforation line 1300 in consideration of thickness and the like. As the perforated line 1300 is formed in this way, the user can remove the cutout 1600 along the perforated line 1300 when using the molded film 1000 .
