As the core material 6 of the thread-like member 5, in addition to chemical fiber threads such as nylon thread, polyester thread, and polypropylene thread, natural threads such as cotton thread and silk thread, or metal wires such as copper wire and steel wire are selectively used. Applies to. The core material 6 of the thread-like member 5 includes a single thread such as nylon thread, or more preferably a thread made of 20 to 30 Teflon filaments. In the case of the nylon string mentioned above, considering the ease of grasping when opening a sealed bag, it is 300μ.
It is more than double the thickness of a normal bag (about 100μ on one side and 200μ on both sides), so when the bags are stacked, the area where the thread-like member is placed will be There is a problem in handling that it becomes bulky. On the other hand, in the case of the latter Tetoron filament, when the thread-like member is fixed on the continuous plastic film by heat and pressure, it is flattened to about 30 μm, and the thickness becomes less than 1/2 of the thickness of the bag mentioned above. Therefore, as mentioned above, it does not become bulky, and since the width is obtained by the flattening, there is no problem with ease of taking out when opening the package. That is, the thread-like member 5 in this invention
The core material 6 is such that the end portion 5a thereof is easy to grasp and take out when opening the sealed bag-like object, and the thickness of the thread-like member is small relative to the thickness of the sealed bag-like object. It is possible to form a relatively thin layer without increasing the thickness locally;
Furthermore, in the process of pulling up the grabbed end portion 5a, the plastic film forming the bag must have a strength suitable for cutting the plastic film forming the bag along the line of arrangement of the filamentous member of the sealed bag-like object. The present invention is not limited to the above-mentioned exemplary core materials. The peripheral surface coating layer 7 of the thread-like member 5 is made of a heat-fusible material selectively selected from heat-fusible resins that can be applied to the heat-fusible plastic film layer forming the inner surface of the enclosure. It is composed of The filamentous member 5 prepared as having such a structure is similar to the laminated continuous film member 2.
A fixing treatment is performed on the heat-fusible plastic film layer 4 side. The laminated continuous film member 2 is provided with cutouts 8 on at least one straight line along a predetermined length direction at predetermined intervals in the length direction. The thread-like member 5
are arranged to pass through the point of the notch 8 and cross the continuous film member 2 orthogonally.
The cutout 8 is for making it easier to take out the end portion 5a of the thread-like member 5 after making the bag. The cutout 8 is designed for the continuous film 2 in the manner shown in FIGS. 1, 3A and 3B. First, according to the example shown in Figure 1,
The cutout 8 is provided on one or both of the edges 9 along the length of the continuous film member 2. On the other hand, according to the example shown in FIG. 3A, the notches are formed along the center lines C and L along the length of the continuous film member 2'.
It is formed by notched holes 8' provided at predetermined intervals in the length direction. In this case, in addition to the central notch hole 8', notches 8 may also be provided on both side edges 9, 9 along the length direction of the continuous film member 2'. The example shown in FIG. 3B is a modified example in which notch holes 8' are further provided on equal dividing lines L 1 and L 2 in the width direction along the length direction of the continuous film member 2''. In the case of this example as well, another notch is provided on both side edges 9, 9 along the length direction of the continuous film member 2'' on the transverse line connecting the notch holes 8', 8', as described above. 8, 8 may be provided.

ことができる。 FIG. 5 shows the continuous film member 2' shown in FIG.
An example of bag making is shown below. In this example, a continuous film member 2' shown in FIG. 3 and a separately prepared continuous film member 10' having a heat-fusible plastic film layer on one side are used.
The heat-fusible plastic layers are stacked one on top of the other so that they face each other, and heat-sealed 17 in relation to the arrangement position of the thread-like members 5 and the center line (C, L) position.
processed and cut along the center line heat line and the transverse heat seal line to obtain a bag-like article 1.
8. According to this embodiment, a separately prepared continuous film member 10'
For example, a continuous film member consisting of, in order from the outer layer, an unstretched nylon layer 19 that is deeply squeezed by heat molding, a poval and ethylene copolymer layer 20 having gas barrier properties, and a polyethylene layer 21 as a heat sealing layer is applied. By doing so, a sealed bag-like article 22 having a form as shown in FIG. 6 can be made.

あるといえる。 According to the plastic film for producing sealed bags of this invention having the above structure, a sealed bag equipped with a thread-like member that allows the sealed bags to be opened easily and cleanly is stored therein. It can be designed in a wide variety of ways depending on the type and form of the items to be stored, and depending on demand, it can be provided as a plastic film or as a three-sided bag sealed on three sides in the desired form. In that respect as well, it can be said to be extremely practical and effective.
