JPS5842292Y2 - Static electricity eliminating bag - Google Patents

Description

[Detailed description of the invention] The present invention relates to a static electricity-eliminating bag used for packaging items that are sensitive to static electricity, such as electronic components and X-ray photosensitive films, and its main purpose is to The object of the present invention is to provide a static electricity-eliminating bag that prevents static electricity damage of stored items and has the necessary strength to withstand the load of stored items.

Conventionally, synthetic resin films have been used as bags for items that are sensitive to static electricity, such as electronic components and X-ray photosensitive films. Various types of static electricity damage occurred, and the quality deteriorated significantly.

The present invention has been devised in view of the above, and will be described in detail below based on an embodiment shown in the drawings.
Fig. 1 is a partially cutaway perspective view of the proposed product, and Fig. 2 is a partially enlarged sectional view of Fig. 1.
' is a reinforcing layer made of synthetic resin film, and has a density of 0.
．． A film made from high-density polyethylene of 94 g/cc or more, stretched 6 to 16 times in the horizontal axis direction, with a thickness of 10 to 10
It is preferable to use a synthetic resin-axially stretched film with a thickness of about 100 μm, and 2.2′ is a metal foil such as aluminum foil laminated on one side of the reinforcing layer 1, 1′, with a thickness of about 7 to 50 μm. is preferable, and 3 is a sealant layer laminated on the surface of one metal foil 2', in which a low-density polyethylene film, EVA film, or ionomer resin film is applied to the entire surface or peripheral portion of the metal foil (a sealant layer formed by laminating this layer) 4 is a metal foil laminated sheet formed by layering the metal foil 2 on one side of the reinforcing layer 1 as described above, and 5 is a metal foil laminate sheet formed by layering the metal foil 2' on one side of the reinforcing layer 1' and a sealant layer on that surface. It is a sealant laminated sheet formed by layering 3 and 6.
To form a bag, the metal foil laminated sheet 4 and the sealant laminated sheet 5 are pulled so that both reinforcing layers 1 and 1' are located on the outer surface layer of the bag and the stretching directions are the same. They are aligned and stacked facing each other, and their peripheral edges are melted and pasted (this is the welded part made into one piece).

In addition, it is preferable that the sealant layer 3 be formed only on the peripheral edge of the metal foil 2' in terms of discharge properties.

As mentioned above, the present invention includes a metal foil laminated sheet 4 formed by layering a metal foil 2 such as an aluminum foil on one surface of a reinforcing layer 1;
A sealant laminated sheet 5 is formed by layering a metal foil 2' such as aluminum foil on one surface of the reinforcing layer 1' and a sealant layer 3 on that surface, and both reinforcing layers 1, 1'
The sealant layer 3 is placed on top of each other so as to face each other so as to be located on the outer surface of the bag body, and the sealant layer 3 is melted and adhered to form a bag-like O-shaped structure. Static electricity generated due to the friction of objects is discharged by the metal foils 2, 2' provided on the inner surface of the bag so as to come into contact with the stored objects, thereby preventing static electricity damage to the stored objects, which conventionally occurs. Outer surface reinforcement layer 1,
Since the metal foil 2 is layered, there is no damage to the metal foil 2 and no bag breakage due to this.Furthermore, by using synthetic resin stretched films whose stretching directions are aligned as the reinforcing layers 1 and 1', tearability and tearability are improved. It has excellent directionality, and since it has the sealant layer 3 integrally on one side of the reinforcing layer 1', it also has features such as being able to be mass-produced when making bags.
