[0020] The following specific embodiments are used to describe the technical solution of the utility model in detail. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.
[0021] Example 1
[0022] Please refer to Figure 1-Figure 2 , Figure 1 This is a schematic diagram of the overall structure of the utility model antistatic container bag. Figure 2 It is a schematic diagram of the exploded structure of the bag bottom (or bag body) of the utility model.
[0023] An antistatic container bag comprises a container bag body 1, which is composed of a bag bottom 2 and a bag body 3. The bag bottom 2 and the bag body 3 form a cavity 4, and the cavity 4 is used to load the contents. The bag bottom 2 and the bag body 3 each sequentially comprise an inner layer 5, a first middle layer 6, a second middle layer 7, a third middle layer 8 and an outer layer 9, wherein the inner layer 5 is an inner antistatic layer, the first middle layer 6 is an inner aluminum foil layer, the second middle layer 7 is a PET layer, the third middle layer 8 is an outer aluminum foil layer, and the outer layer 9 is an outer antistatic layer.
[0024] When the antistatic container bag is in use, firstly, since the inner layer 5 is the inner antistatic layer and the outer layer 9 is the outer antistatic layer, even if the static charge generated by friction is relatively small, and since the first middle layer 6 is the inner aluminum foil layer and the third middle layer 8 is the outer aluminum foil layer, even if the inner layer 5 (or the outer layer 9) generates static charge due to internal friction (external friction), the static charge also escapes from the inner layer 5 (or the outer layer 9) to the first middle layer 6 (or the third middle layer 8), preventing the generation of excessive high voltage in a local area and causing safety risks. The PET layer separates the inside and the outside to avoid mutual influence.
[0025] Those skilled in the art should know that although Figure 1 The bag top is not shown in the figure, but after the container bag of the present invention is filled, the top of the bag body 3 is sealed together by a sealing line.
[0026] In one or more specific embodiments of the present invention, the inner antistatic layer or the outer antistatic layer can be made of a plastic film made of polyethylene or polypropylene material, and an anionic surfactant is added during the process of making the plastic film from polyethylene or polypropylene material. This preparation process is a prior art, and the polyethylene or polypropylene produced has antistatic properties.
[0027] In one or more specific embodiments of the present invention, the thickness of the inner antistatic layer (outer antistatic layer) is about 32 um, the thickness of the outer aluminum foil layer (or inner aluminum foil layer) is about 10 um, and the thickness of the PET layer is 15 um.
[0028] In one or more specific embodiments of the present invention, the surface resistance of the inner antistatic layer (outer antistatic layer) is 10 6 -10 8 In this range, a better effect of dispersing static charge can be achieved.
[0029] Example 2
[0030] Although Example 1 has better antistatic properties compared with the prior art in the background technology, the ventilation of Example 1 is poor, and the antistatic properties may be further improved.
[0031] Please refer again Figure 1-Figure 2, an antistatic container bag, a container bag body 1, the container bag body 1 is composed of a bag bottom 2 and a bag body 3, the bag bottom 2 and the bag body 3 form a cavity 4, the cavity 4 is used to load the contents, the bag bottom 2 and the bag body 3 each include an inner layer 5, a first middle layer 6, a second middle layer 7, a third middle layer 8 and an outer layer 9 in sequence, the inner layer 5 is an inner antistatic layer, the first middle layer 6 is an inner aluminum foil layer, the second middle layer 7 is a PET layer, the third middle layer 8 is an outer aluminum foil layer, the outer layer 9 is an outer antistatic layer, the inner layer 5 is uniformly provided with first pinholes 10, the first middle layer 6 is uniformly provided with second pinholes 11, the second middle layer 7 is uniformly provided with third pinholes 12, the third middle layer 8 is uniformly provided with fourth pinholes 13, and the outer layer 9 is uniformly provided with fifth pinholes 14.
[0032] When the antistatic container bag is in use, firstly, since the inner layer 5 is the inner antistatic layer and the outer layer 9 is the outer antistatic layer, even if the static charge generated by friction is relatively small, and since the first middle layer 6 is the inner aluminum foil layer and the third middle layer 8 is the outer aluminum foil layer, even if the inner layer 5 (or the outer layer 9) generates static charge due to internal friction (external friction), the static charge also escapes from the inner layer 5 (or the outer layer 9) to the first middle layer 6 (or the third middle layer 8), preventing the excessive high voltage in the local area from causing safety risks. The PET layer separates the inside and the outside to avoid mutual influence. The first pinhole 10, the second pinhole 11, the third pinhole 12, the fourth pinhole 13, and the fifth pinhole 14 are set, on the one hand, so that there is a channel for the air in the cavity 4 to be discharged after the contents of the cavity 4 are accommodated between the inner layer 5, the first middle layer 6, the second middle layer 7, the third middle layer 8 and the outer layer 9, and on the other hand, it also makes the cavity 4 communicate with the outside, reducing the generation of static charge (static charge is more likely to be generated in a confined space).
[0033] In one or more specific embodiments of the present invention, the inner antistatic layer or the outer antistatic layer can be made of polyethylene or polypropylene material to form a plastic film, and an anionic surfactant is added during the process of making the polyethylene or polypropylene material into a plastic film.

The first pinhole 10, the third pinhole 12, the fifth pinhole 14, the second pinhole 11 and the fourth pinhole 13 can be formed when forming the inner and outer antistatic layers or the PET layer material.
[0034] In one or more specific embodiments of the present invention, the thickness of the inner antistatic layer (outer antistatic layer) is about 32 um, the thickness of the outer aluminum foil layer (or inner aluminum foil layer) is about 10 um, and the thickness of the PET layer is 15 um.
[0035] In one or more specific embodiments of the present invention, the surface resistance of the inner antistatic layer (outer antistatic layer) is 10 6 -10 8 In this range, a better effect of dispersing static charge can be achieved.
[0036] In one or more specific embodiments of the utility model, the first pinhole 10 and the second pinhole 11 are staggered, the second pinhole 11 and the third pinhole 12 are staggered, the third pinhole 12 and the fourth pinhole 13 are staggered, and the fourth pinhole 13 and the fifth pinhole 14 are staggered. Through the staggered arrangement, the air flow flows between the layers, thereby improving the overall performance of the product.
[0037] In one or more specific embodiments of the present invention, the diameters of the first pinhole 10 , the second pinhole 11 , the third pinhole 12 , the fourth pinhole 13 , and the fifth pinhole 14 are about 2-5 um.
[0038] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
