(Industrial Application Field) The present invention relates to a conductive film having transparency and thermal adhesive properties, and a bag-made product thereof. (Prior art) Conventional transparent conductive films include those in which noble metals such as gold and nickel are vapor-deposited on a transparent base film such as polyester film, and conductive films with particle diameters of 0.4μ or less deposited on transparent base films. There are those coated with a transparent conductive paint whose main component is a static fine powder, and those made into a film after kneading an antistatic agent into a thermoplastic resin. (Problems to be Solved by the Invention) However, although the above-mentioned transparent conductive film has various advantages, it also has disadvantages. In other words, those with precious metals such as gold and nickel deposited on them are
Although it has excellent conductivity and transparency, it is extremely expensive because it uses precious metals as raw materials and also undergoes a vapor deposition process.Moreover, polyester film, polyamide film, etc. are often used as the base material. It lacks versatility because it does not have thermal adhesive properties and cannot be processed into bags or the like as it is. In addition, a transparent base film coated with a transparent conductive paint has a fairly excellent surface conductivity, for example, a surface resistivity of 10 7 Ω or less. Products made with this material are weak and the non-coated surface remains electrically charged, while bags made from this material become electrically charged due to friction inside the bag, and exhibit the effect of being a conductive film. do not. In addition, polyolefin films mixed with antistatic agents have thermal adhesion properties, but have insufficient electrical conductivity, so bags made using this film will not react when high voltage is applied to the outside of the bag. This cannot be sufficiently shielded and the antistatic bag cannot achieve its full effect. (Means for Solving the Problems) The present inventors have arrived at the present invention as a result of studies to solve the above-mentioned drawbacks. That is, the present invention has the structure shown in FIG. 1, which includes, in order, a transparent conductive paint coating layer, a transparent insulating base film layer, an adhesive layer, and a heat-adhesive transparent antistatic layer. A heat-adhesive transparent conductive composite film having a surface resistivity of 10 7 Ω or less on the transparent conductive paint coating layer side and a surface resistivity of 10 10 Ω or less on the heat-adhesive transparent antistatic layer side. More preferably, the coating amount is 1 g/m 2 on the transparent conductive paint coating layer having the structure shown in FIG.
The heat-adhesive transparent conductive composite film according to (1), which has the following transparent resin coating layer and has a surface resistivity of 10 7 Ω or less on the side of the transparent resin coating layer. It is. and (3) having a structure of a transparent conductive paint coating layer, a transparent insulating base film layer, an adhesive layer, and a heat-adhesive transparent antistatic layer in this order, and having a surface resistivity on the side of the transparent conductive paint coating layer. is 10 7 Ω or less, and the surface resistivity of the heat-adhesive transparent antistatic layer side is 10 10 Ω or less. and more preferably, (4) a coating amount of 1 g/m 2 on the transparent conductive paint coating layer.
The bag according to (3), which uses a heat-adhesive transparent conductive composite film having the following transparent resin coating layer and having a surface resistivity of 10 7 Ω or less on the side of the transparent resin coating layer. It is. A detailed explanation will be given below based on FIGS. 1 and 2. 1 is a heat-adhesive resin film layer to which an antistatic agent is added, and preferably has a surface resistivity of 10 10 Ω or less. As the heat-adhesive resin used for this, those normally used as heat-adhesive resins such as polyethylene, polypropylene, ethylene vinyl acetate, and ionomer resins are used. Examples of the antistatic agent added to the thermoadhesive resin include commonly used antistatic agents and compositions of these and alkali metal salts. 2 is an adhesive layer between 1 and 3, and may be an adhesive layer for dry lamination or an adhesive layer for extrusion lamination. 3 is an insulating base material layer of 4-transparent conductive paint layer, and for example, a general-purpose plastic film such as a polyester resin film, a polyamide film, or a vinyl chloride film can be used. 4 is a transparent conductive paint layer, for example, the particle size is
Consisting of conductive metal oxide fine powder of 0.4μm or less and binder resin, the coating amount of this paint layer is 0.5μm or less.
The range of ~5.0g/ m2 is preferable; if it exceeds 5.0g/ m2 , transparency will be insufficient, and if it is less than 0.5g/ m2 , excellent conductivity will not be obtained, and both will be less than the original value. I can't achieve my goal. Further, the surface resistivity of the conductive paint layer used in the present invention is preferably 10 7 Ω or less. In the present invention, the abrasion resistance strength of the 4-conductive paint layer can be improved by further providing a 5-resin coating layer on the surface of the 4-conductive paint layer. As the resin used for the 5-resin coating layer, polyether resins, polyester resins, polyacrylic resins, etc. are preferable, and transparency can be improved by coating. If desired, the hardness of the coating layer can be further increased by blending an isocyanate compound into the coating layer. In addition, it is preferable that the 5-resin coating layer has a weight of 1 g/m 2 or less, and 0.5
g/m 2 or less is more preferable. If it exceeds 1 g/m 2 , the good surface resistance obtained by the 4-conductive paint layer is inhibited, and 5- the high surface resistance inherent to the resin coating layer is restored, making it impossible to obtain an antistatic effect. In order to process the transparent conductive film having the structure shown in FIG. 1 or FIG. , and then heat-sealed into a bag shape. Moreover, the bag obtained by the above method can be closed at any time. (Example) The present invention will be specifically described below with reference to Examples, but the present invention is not limited thereto. Example 1 A biaxially oriented polyester film with a thickness of 12 μm
Conductive paint (Syntron C-4402, manufactured by Shinto Paint Co., Ltd.) containing SnO 2 fine powder as the main component was converted to a solid content of 1.2
After coating and drying, the surface opposite to this coated surface and the corona-treated surface of a heat-adhesive antistatic film made of polyethylene resin with a thickness of 50 μm and a surfactant and an alkali metal salt added are coated. Laminated using dry laminating adhesive. Table 1 shows various characteristic values of the obtained composite film. Example 2 On the coated surface of the polyester film, which had been coated with a conductive paint and dried in the same manner as in Example 1, a polyacrylic transparent resin paint was further coated and dried to a solid content of 0.2 g/m 2 . , A thermal adhesive antistatic film was laminated in the same manner as in Example 1. Table 1 shows various characteristic values of the obtained composite film.

It not only has a low surface resistance of less than Ω and has a high antistatic effect, but also has a surface resistance of 10 6
It has an even smaller surface resistance on the order of Ω, shielding electric fields from the outside, and at the same time, the insulating properties of the base film prevents charges from the outside from being introduced into the inside of the bag. Further, by further providing a resin coating layer on the conductive coating layer as in Example 2, the surface hardness can be improved and scratch resistance can be improved, and at the same time, the haze value and transparency can also be improved.
