[Industrial applications]

 The present invention relates to a product packaging bag intermediate product which is cut into two product packaging bags.

[0002]

[Prior art]

 Conventionally, a header-equipped product packaging bag has been widely used as a packaging bag for small-sized products, and various forms thereof are known. However, many of these small products are small-scale rod products, for example, fine multi-product products such as fishing hooks and fine products such as machine screw parts, and product packaging bags with the same print pattern are used. Producing small quantities of what can be produced according to the size of the product has the drawback that it is costly and the ratio of packaging cost to the product is large.

[0003]

[Problems to be solved by the device]

 An object of the present invention is to provide an intermediate product for a product packaging bag, which can be used in a desired size on the product packaging bag for a small amount of rod products just before the packaging.

[0004]

[Means for Solving the Problems]

 The inventor of the present invention, if a bag in which the header portions are located above and below and the intermediate bag body portions are joined together is manufactured in advance, the bag is cut at a position deviated from the center portion of the bag body portion. Paying attention to the fact that two types of header-equipped product packaging bags with long dimensions of the bag part and the other short dimension can be obtained, and if the cutting positions are changed to two, four types of product packaging bags can be obtained. The present invention has been completed based on the idea of a product packaging bag intermediate that can manufacture various product packaging bags as desired from one type of product packaging bag manufactured in the bag manufacturing process. That is, according to the present invention, the thermoplastic resin film 1 is extended downward from the lower edge of the upper header resin sheet 2 and is folded back at the lower edge, and the lower header resin sheet 2 ′ is folded into the lower folded portion 6. The resin film 1 is sandwiched, and the resin film 1 is fused at a position near the upper edge of the lower header resin sheet 2 ′ to separate it from the header portion, and is folded back at the lower edge of the lower header resin sheet 2 ′. The resin film 1 is folded back again at the upper edge of the upper header resin sheet 2, and the folded back end 7 of the resin film is fused and fixed at the lower edge of the upper header resin sheet 2, and the resin film is laminated on the front and back sides. The two header parts that are fused and fixed by fusion with the resin sheet interposed between the side edges 8 and 9 on both sides of 1 are connected by one bag part. Featured product packaging bag intermediates and It is an intermediate product of a product packaging bag, and the bag body has a resin sheet 10 for the core material of the bag body built-in, and is placed on the lower edge of the resin sheet 2 for the upper header and the resin sheet 2'for the lower header. The present invention provides an intermediate product for a product packaging bag, which is formed of an integral resin sheet having its edge connected with a resin sheet 10 for a bag body core material. For the resin film and resin sheet used in the present invention, thermoplastic resins such as polyethylene, polypropylene, polystyrene, polyester and nylon can be used without particular limitation, but from the viewpoint of processability, polyolefin such as polypropylene and polyethylene is used. It is desirable to use a film or a laminated film thereof. The thickness of the resin film of the present invention is not particularly limited, but a thin film of about 20 to 100 μm can be used. The thickness of the resin sheet of the present invention is not particularly limited, and a flexible sheet having a thickness of, for example, 60 to 500 μm, preferably 80 to 300 μm can be used.

【Example】

 The present invention will be described in more detail with reference to the drawings of the embodiments. As shown in FIG. 1, the product packaging bag intermediate of the present invention has a structure in which there are two header parts at the top and bottom, and a bag part between them. The resin film 1 fused and fixed to the lower edge of the resin sheet 2 for the upper header extends downward to reach the resin sheet 2'for the lower header, and the lower folded portion 6 of the resin sheet 2'for the lower header. And is fused and fixed by two heat sealing portions 3'on the front and back sides at the upper edge of the lower header resin sheet 2 '. The resin film 1 folded back to the back side extends upward from the heat seal portion 3 ′ on the back side, is welded at the lower edge of the upper header resin sheet 2, and is folded back at the upper edge of the upper header resin sheet 2. The tip of the resin film 1 is fused and fixed to the lower edge of the resin sheet 2 for the upper header. On the other hand, the resin film 1 is melt-fused at both side edges in FIG. 2, and is melt-fused together with the upper header resin sheet 2 and the lower header resin sheet 2 '. In this bag, first, a strip-shaped resin film with a predetermined long print pattern is unrolled from the roll, and half-folded at the lower folding part 6, and at this fold, a long unpatterned lower header resin sheet 2 'Is inserted continuously. At the same time, an unpatterned upper heading resin sheet 2 is supplied to the upper part, and the tip of the resin film 1 is once fused and fixed to the lower edge of the resin sheet. Next, the other end of the resin film 1 folded back from the back side of the upper header resin sheet 2 can also be overlapped and fused at the seam portion 4 on the fusion-fixed portion to be manufactured.

In the product packaging bag manufactured in this manner, when the center line of the bag body part is removed and, for example, the bag is cut at the planned cutting point 5 in FIG. Can be manufactured. In the case of a wide variety of products in the same field, the same print pattern can be used for printing the header portion and the bag body portion. The product can be packaged by inserting the product through the cutting opening and sealing the opening by heat sealing. The product packaging bag intermediate of FIG. 3 shows another embodiment. In this case, the heat-sealing portions 3 and 3 ′ forming the association of the header portion and the bag portion are separated from the edges of the upper and lower header resin sheets 2 and 2 ′, and only the resin film 1 on the front and back sides is fused. The difference is that the resin sheet is free from this fusion. 4 is different from the embodiment of FIG. 1 in that the upper and lower header resin sheets 2 and 2'of FIG. 1 are one continuous thick sheet. The thick sheet of the bag body portion functions as the upper and lower header resin sheets 2 and 2 ', and the middle portion resin sheet 10 for the bag body core material functions as the core material of the bag body portion. That is, the resin sheet 10 for the core material of the bag body is connected between the lower edge of the resin sheet 2 for the upper header and the upper edge of the resin sheet 2'for the lower header of the product packaging bag intermediate of the embodiment of FIG. These are made of one integrated resin sheet. Further, as another function of this core material, a bag body portion for storing an article can be formed on the front and back of a thick resin sheet to store two types of articles separately. The product packaging bag obtained by cutting the product packaging bag intermediate can accommodate a pair of thin small products on the front and back. The opening of the product packaging bag obtained by cutting the product packaging bag intermediate of the present invention can be sealed with a heat seal or an adhesive after storing the product.

[Effect of device]

 The intermediate product packaging bag of the present invention has a header part at the top and bottom, and these two header parts are connected by one bag part. Then, by removing the center line of the bag and cutting the bag, two types of bags having a desired size are obtained. If the product packaging bag intermediate of the present invention is manufactured, even one type of product packaging bag intermediate manufactured by mass production can be used for the packaging of a small variety of products even in the packaging of a wide variety of small quantities. There is an advantage that an inexpensive product packaging bag can be provided. In addition, this manufacturing method can be easily manufactured by improving the existing bag manufacturing apparatus.
