Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a resin film bag for storing clothing and the like during the product distribution process and a manufacturing method thereof.

BACKGROUND OF THE INVENTION Generally, clothing bags are made by folding a transparent resin film at the center and fusing both ends, and the product name, size, etc. are printed in gravure on the inner or outer surface of the bag. ing. However, this type of clothing bag has the problem that it can only be used for clothing that has been printed with gravure printing. In other words, even for the same type of clothing, the printing content must be changed depending on whether it is for men, women, or the model number, and it is necessary to make bags for each type of clothing, and the inventory is also limited. You have to carry the bag itself.

Therefore, the present applicant has already filed the patent application No. 58-60493.
No. (Japanese Unexamined Patent Publication No. 59-187549), a bag in which a band made of a resin film on which a product name, etc. is printed in advance is sandwiched inside the bag body and heat-welded to the bag body only at both ends, and its manufacture. proposed a method. According to this invention, it is possible to significantly reduce production costs, especially printing costs and printing plate costs.

On the other hand, in this case, the band is welded only at both ends, and the middle part is floating, so there is a risk that clothing or the like may get caught on the edge of the band when it is stored.

Means for Solving the Problems Therefore, in the resin film bag making according to the first invention, a band made of a resin film on which a product name etc. are printed is inserted into a bag body, and the bag body of this band is The opening side edge of the bag is welded to the front or back side of the bag body, and both ends are heat welded to the bag body.

The manufacturing method according to the second invention comprises folding a long body of resin film at approximately the center to form a bag body;
A band made of resin film with a product name printed on it is sandwiched between the front and back sides of the bag body, and the opening side edge of the bag body is heated with a hot roller on the front or back side. It is characterized by being welded and cut at predetermined intervals.

Embodiment FIGS. 1 and 2 show an embodiment of the resin film bag making according to the present invention, which is made of a transparent resin film, for example, a polyethylene film, and has both ends of a front surface portion 1 and a back surface portion 2 folded back at the lower side a. Parts b and b are melted and the upper part of the surface part 1 is extended to form a lid part 3, and inside is a band 5 made of a resin film, for example, a polyethylene film, which is attached at both ends of the bag body. The parts b and b are welded at the same time as they are fused, and the edge 5a of the band 5 near the opening 4 is welded to the surface part 1 over the entire length in the lateral direction. Band body 5
The product name, manufacturer name, product size, etc. are printed in advance on the surface of the device, and the printed surface is located on the surface portion 1 side. Further, a soft adhesive is applied to the lid portion 3, and a release paper (not shown) is adhered thereto.

Clothes 10 are stored in the resin film bag constructed as described above, the opening 4 is closed by peeling off the release paper and adhering the lid 3 to the back surface 2, and the bag is placed in the distribution process. When storing the clothing 10, since the edge 5a of the band 5 near the opening 4 is welded to the surface portion 1, the clothing 10 does not get caught on the band 5 and can be stored smoothly. can.

Next, an embodiment of the manufacturing method according to the present invention will be described.

First, as shown in FIG. 3, a plate 21 with printed content engraved in the longitudinal direction of a wide transparent resin film 20
A plurality of lines are printed according to the width W of the band 5, and a slitter is used to cut each width W and both edges, and the band is wound up.

On the other hand, as shown in FIG. 4, a so-called melt-cut bag is manufactured using a plain resin film fabric 30 using a conventional bag making machine. At this time, the already wound band 5 is inserted into a predetermined place to form the film fabric 30.
A base plate and a heating roller 31 (not shown) are also conveyed together.
The surface portion 1 and the unprinted edge 5a of the band 5 near the opening 4 are welded together. Then, while conveying the fabric 30 and the band 5 together, both ends are melt-cut at the same time.

Note that the resin film bag making and manufacturing method thereof according to the present invention are not limited to the above embodiments, and can be variously modified within the scope of the gist. For example, the band 5 may be welded to the back surface portion 2. In this case, the printed surface is on the back side portion 2 side. Moreover, not only one sheet but a plurality of sheets may be fixed, and the position of the sheet to be fixed may be arbitrary between the opening 4 and the bottom.

Effects of the Invention As is clear from the above description, according to the first invention, at least the edge of the band provided inside the bag body near the opening of the bag body is welded to the front or back side of the bag body. When storing products in the bag body, the products do not get caught on the band and can be stored smoothly.

Furthermore, according to the second invention, even if the step of inserting the strip and fixing it to the bag body is added, it is possible to maintain almost the same bag-making speed as before, and also to print separately on the strip. As a result, printing costs and plate costs can be significantly reduced.

Furthermore, since the portion welded by the heat roller is the edge of the band and the welded area is extremely small, there are almost no welding wrinkles and no disturbance of the printed surface.
