[0048] Figure 1 is a first embodiment of the present invention having a top view of the bag with a belt, Figure 2 be Figure 1 II-II line sectional view. As shown, the bag 100 having a band includes: the bag body 110, which has a first side 111A and a second side 111B formed by the membrane and opposed to each other; and 120, which is joined to the first side of the bag body 111A and the second side 111B, respectively, and delineated to form a side of the storage space SP between the first side 111A and the second side 111B.
[0049] The bag body 110 is formed, for example, by a single or multilayer thermoplastic resin film. Thermoplastic resins may also be specifically low-density polyethylene (LDPE), linear-chain low-density polyethylene (LLDPE), or polypropylene (PP). PP can also be homogeneous polypropylene (HPP), random polypropylene (RPP), or block polypropylene (BPP). In the case where the bag body 110 is formed by a multilayer film, it is also possible to use biaxial str...

[0066] Figure 10 is a second embodiment of the present invention having a top view of the bag with a chain strap, Figure 11 be Figure 10 XI-XI line sectional view. As shown, the bag 200 having a chain strap comprises: a bag body 110, which is the same as the first embodiment described above; and a chain strip 220, which is engaged with the first side of the bag body 111A and the second side 111B respectively, and delineated to form a side of the storage space SP between the first side 111A and the second side 111B.
[0067] The clamping belt 220 is as Figure 11 Shown in the cross-sectional shape includes a long strip of members of the first part 220A and the second part 220B opposed to each other. The first portion 220A and the second portion 220B include, respectively, a first thick-walled portion 121A, 121B, a second thick-walled portion 122A, 122B, a thin-walled portion 123A, 123B, and a base strip constituting a zipper portion 224A, 224B and a snap-in portion 225A, 225B, in t...
Embodiment
[0077] To the references in the above Figure 11 Illustrated second embodiment of the present invention of the clip belt, performed open evaluation.
[0078] In the clamping belt of Example 1, as a material of the thick wall, the preparation density is 913kg / m 3 3. The melt flow rate is 4.0g / 10 minutes of straight chain low-density polyethylene, as a thin-walled material, the preparation density is 953kg / m 3 3. The melt flow rate is 5.0g / 10 minutes of high-density polyethylene. After extruding these raw material components into shape with an extruder, a clip-chain belt is made by water cooling. The thickness of the thick-walled part of the clamping belt is 330 μm, the length of the thick-walled part is 19mm in the width direction, the film thickness of the thin-walled part is 60μm, and the length in the width direction of the thin-walled part is 3mm.
[0079] In the clamping belt of Example 2, as a material of the thick wall, the preparation density is 913kg / m 3 3. The melt flo...
