Depression is provided with face；The protective layer is polytetrafluorethylecoatings coatings, and on the outer surface coated in the basic unit, its thickness is
5-15um；The antistatic backing is the braiding layer for including antistatic fiber；The bag body also includes hygroscopic material, the hydroscopic substance
Matter is placed in the depression in the basic unit.
The present invention further thes improvement is that the depression set in the basic unit is embossed depression.
The present invention further thes improvement is that the thickness of the protective layer is arranged to 10um.
The present invention further the improvement is that, the antistatic fiber be metallic conduction fiber, carbon conductive fiber,
One or more in electrically conductive organic fibre.
The present invention further thes improvement is that the braiding layer also includes what is be interweaved with the antistatic fiber
Polyester fiber, nylon fibre, acrylic fiber or spandex fibre.
The present invention further thes improvement is that the hygroscopic material is calcium oxide, silica gel, clay, high-hydroscopicity gather
One kind in compound.
The present invention further thes improvement is that, compound for PUR bonding between the basic unit and the antistatic backing
Or pressurization is compound.
Compared with prior art, packing electronic component bag provided by the invention, have absorb packaged by inner space or
The effect of moisture in electronic component, overcomes the problem of electronic component is easily influenceed and damaged by moisture, and in packaging bag
Special hygroscopic material bag need not be increased, packaging space is rationally make use of, saved packaging material；At the same time, the packaging
Bag can effectively protect its interior electronic component from the infringement of electrostatic, solve electronic component in storage, transhipment by electrostatic
The problem of impact, it is ensured that the validity of electronic component, the service life for extending electronic component.
Brief description of the drawings
Fig. 1 is the cross section structure schematic diagram of packing electronic component bag bag body in one embodiment of the invention.
Following embodiment will combine above-mentioned accompanying drawing and further illustrate the present invention.
Embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These accompanying drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention.
Fig. 1 is referred to, the invention provides a kind of packing electronic component bag, including bag body, the bag body is from outside to inside
Include protective layer 10, basic unit 20 and antistatic backing 30 successively.
The basic unit 20 is aluminum membranous layer, and it mainly plays a supportive role, and assigns the bag body enough intensity.
It is coated with the protective layer 10 on the outer surface of basic unit 20, in the present embodiment, the protective layer 10 is poly-
Tetrafluoroethene coating, it is coated on the outer surface of the basic unit 20 by way of spraying or roller coat, the protective layer 10
Thickness be arranged to 5-15um, it is preferred that the thickness of the protective layer 10 is arranged to 10um, and its main function is protects the base
Layer 20, prevent the aluminum membranous layer 20 to be oxidized corrosion, overcome the aluminum oxide that is formed on the aluminum membranous layer after oxidation can weaken it is described
The defects of antistatic performance of bag body.
The antistatic backing 30 is arranged on the most inner side of the bag body, is the braiding layer for including antistatic fiber, it is acted on
It is the electrostatic in shielding environment, protects the internal electronic component of the bag from the infringement of electrostatic.Wherein, the antistatic is fine
Tie up as the one or more in metallic conduction fiber, carbon conductive fiber, electrically conductive organic fibre, it is in one embodiment, described
Braiding layer also includes polyester fiber, nylon fibre, acrylic fiber or the spandex fibre being interweaved with the antistatic fiber.This
In embodiment, the antistatic backing 30 is single layer structure, it is noted that in the other embodiments of the present invention, it is described anti-quiet
Electric layer 30 can also be sandwich construction.The multi-layer braided Rotating fields of the antistatic backing 30, which first pass through, to be combined into one, then will
The antistatic backing is integrally combined together with the basic unit 20.
The bag body also includes hygroscopic material 100, and depression 201, the suction are provided with the inner surface of basic unit 20
Wet material 100 is placed in the depression 201 in the basic unit 20, for absorbing the internal space of bag or electronic component brings into
Moisture, the drying of the internal electronic component of bag is kept, protects influence and damage of the internal electronic component of the bag from moisture
It is bad.The depression 201 provides space for the 100 possible water swelling of hygroscopic material.To be known in the industry, embossing be with
A pair of knurling rolls for being carved with certain depth decorative pattern pressure rolling aluminum membranous layer at a certain temperature, make aluminium film layer surface produce ridge design,
The technique for improving aluminium film surface aesthetic feeling.In the present embodiment, the depression 201 set on the inner surface of basic unit 20 is recessed to be embossed
Fall into, the size and number of the depression 201 can be according to the decision of the amount for the hygroscopic material 100 to be accommodated, the depression 201
Various patterns can be arranged as, lift the aesthetics of the packaging bag.
The hygroscopic material 100 can be one kind in calcium oxide, silica gel, clay, high water absorbency polymer, these moisture absorptions
Material is also referred to as drier, is typically rendered as powdered or graininess.Common drier composition is used equally for being made
Hygroscopic material 100 in the present invention, therefore the hygroscopic material 100 in the present invention is not limited to the above-mentioned species enumerated.
It is compound that combination between the basic unit 20 and the antistatic backing 30 can use PUR to bond compound or pressurization.
Packing electronic component bag provided by the present invention, the external side of bag are the aluminum membranous layer coated with the protective layer 10
20, necessary support strength is provided for the packaging bag, and the moisture or dust that can completely cut off outside packaging bag；The internal side of bag is
The side of the packaged electronic component of contact is the antistatic backing 30, can effectively protect and protect electronic component from quiet in it
The impact of electricity, extends its service life；The antistatic backing 30 is fiber braiding layer, thereon with hole, the hygroscopic material
100 are placed between the basic unit 20 and the antistatic backing 30 in the depression 201 of the basic unit 20, and it is efficient to can pass through the hole
The moisture on the packaging bag inner space or electronic component is absorbed, overcome electronic component is easily influenceed easily by moisture
The problem of damage.
In addition, those skilled in the art can also do other changes in spirit of the invention.Therefore these are spiritual according to the present invention
