DESCRIPTION OF THE PREFERRED EMBODIMENTS The film and cover tape used in the present invention are not particularly limited, and any plastic film such as polyethylene, polypropylene, vinylon film and the like can be used. The position of the slit 6 can be freely set, but in order for the inside air to be pushed out without resistance when inserting the product, the lower part of the bag, which is away from the upper opening which is the insertion opening of the product, is more preferable. . The width of the slit 6 can be any size as long as the air can escape freely and the size of the inside of the slit 6 does not protrude, but is usually 2 to 20 m.
m, preferably 5 to 15 mm. The cover tape 4 can be used inside or outside the bag for the slit 6. The welding or bonding of the cover tape 4 can be performed at the lower edge 7 of the upper back film or at the upper edge 8 of the lower back film. Further, when the cover tape 4 is used inside the bag body with respect to the slit 6, the position of the welding or the adhesive seal is preferably at the lower edge 7 of the upper back film, and the cover tape 4 is positioned outside the bag body with respect to the slit 6. When used, the position of the weld or adhesive seal is preferably at the upper edge 8 of the lower backing film. When the product is inserted into the bag, when the cover tape 4 is inside the bag with respect to the slit 6, the product is sealed with the cover tape 4 at the lower edge 7 of the upper back film, and the product is inserted into the slit 6.
Can be inserted smoothly without being caught on the cover tape. When the cover tape 4 is outside the bag body with respect to the slit, it is better that the product is sealed with the cover tape 4 at the upper edge 8 of the lower back film. It is convenient without protruding. The width of the cover tape 4 is usually 10 to 50
mm, preferably 20 to 40 mm. An adhesive for sealing or a release paper 5 with an adhesive is adhered to the upper edge of the front film 1, and has a function of folding the product and inserting the product to seal the bag. If a cylindrical film sheet is used as a raw material for the production of the bag of the present invention, the bag can be produced continuously and easily at low cost, which is advantageous. That is, operations such as cutting, heat sealing, welding and the like can be easily performed while continuously feeding the cylindrical film sheet by the roller.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be explained in more detail with reference to the drawings of an embodiment. Embodiment 1 As shown in FIGS. 1 and 2, the front film 1 and the lower back film 2 are continuous at the lower edge to form a bottom and the side edge of the upper back film 3 , To form a bag of 50 × 30 cm. At this time, a slit 6 of 5 mm is horizontally provided between the lower back film 2 and the upper back film 3, and the cover tape 4 of 30 mm wider than the width of the slit 6 is used to cover the slit from the outside of the bag body. The slit 6 was covered, and both ends of the cover tape 4 were integrally welded to the side edge of the bag. The lower edge of the cover tape 4 was welded and sealed to the upper edge 8 of the lower back film. Further, a release paper 5 with an adhesive was attached to the upper edge of the front film 1. The fiber product was inserted into and stored in the bag through the opening 9 of the bag. The air inside the bag pressed by the fiber product is pushed out of the bag through the slit 6, so that the bag does not bulge or bulk with the air inside, and subsequent work and handling are facilitated. . Embodiment 2 As shown in FIG. 3, the cover tape 4 covering the slit 6 is formed from the inside of the bag body to the slit, and the sealing of the cover tape 4 is performed by welding the upper edge of the cover tape 4 and the lower edge of the upper back film. Example 7 was carried out in the same manner as in Example 1 except that the measurement was conducted between Step 7 and Step 7. Example 3 In FIG. 4, the procedure was the same as that of Example 1 except that the upper edge of the upper back film 3 was longer than the front film 1 and the release paper 5 with the adhesive was attached to the upper edge of the upper back film 3. . Example 4 FIG. 5 is the same as Example 1 except that a film having a bottom portion formed by welding a front film 1 and a lower back film 2 at a lower edge is used. Embodiment 5 FIG. 6 shows a hanger cover body. The procedure was the same as Example 4 except that the bottom of the 90 × 50 cm bag was welded and cut according to the shape of the upper part of the hanger. Immediately after the cleaned textile product was ironed into the hanger cover body, the cleaning product was inserted and stored through the opening 9. The air containing moisture went out of the hanger cover body through the slit 6, and the generation of stains, molds, etc. could be prevented. Example 6 A cylindrical film sheet is continuously fed out, a side edge thereof is cut out by a cutter to form a band-shaped film having a cross-sectional shape shown in FIG. 7, and then a lower portion of the back film portion is continuously cut by a cutter. The upper back film 3 is provided at intervals of 10 mm in width to be slits 6 by roller operation.
And the lower back film 2 was continuously spread to form a band-shaped film having a sectional shape shown in FIG. Further, the lower edge of the cover tape 4 is heat-sealed with the upper edge 8 of the lower back film while continuously feeding the cover tape 4 of 35 mm wider than the width of the slit 6 onto the slit 6 to thereby form the front film 1. A release paper with an adhesive was continuously adhered to the upper edge of the film to form a band-shaped film having a sectional shape as shown in FIG.
Next, when the belt-like film of FIG. 9 formed here is switched to one-pitch movement of the film structure by a conventional method, and the side edge of the bag is cut off in the welding step, the bag having the cross-sectional laminated structure of FIG. 2 is manufactured. We were able to.
