Abstract
The utility model relates to an electrostatic prevention shielding composite packaging bag, which comprises a double-layer thin film. The utility model is characterized in that an electrostatic prevention shielding composite thin film of a multilayer structure is adopted, wherein, the internal layer of the composite thin film is a heat sealing layer which is covered with a thin metallic layer which is provided with an insulating layer; a polyester thin film is covered outside the insulating layer, and the surface of the polyester thin film can be covered with an electric conducting oil film. The surface resistance of the utility model with slight conductivity is low, and the utility model with the electromagnetic shielding function can effectively protect a packaged component or a PCB board from the interference and the infringement of an external electric field and an external magnetic field. The utility model with the light shading effect can enable a customer to clearly see a packaged product and the mark of the product in order to confirm.
Description
Technical field
The utility model belongs to circuit card packing technique field, specifically is a kind of anti-static shielding combined package bag, is used for packing pcb board and electronic devices and components etc.
Background technology
At present, the packing of electric sensitive components and printed board adopts the common plastics bag more.Use common plastic bag,, be easy to generate static, cause the inner somewhere of dangerous material rest potential to increase, thereby produce spark discharge, have influence on the safety of goods because of having the influence of high-insulativity in the mutual friction of device phase, bump, external electrical field and magnetic field.Therefore, select and use packing, satisfying under original engineering factor requirement, the conductive material dangerous goods in packaged form goods that the electric conductivity of material and electrical resistivity are low can prevent that static from accumulating the safety effect that plays the protection goods.
Summary of the invention
The purpose of this utility model is to provide a kind of anti-static shielding combined package bag, to satisfy the anti-static shielding packing of electric sensitive components and printed board.
The utility model anti-static shielding combined package bag, comprise bilayer film, it is characterized in that: described film is the anti-static shielding laminated film of multiple-structure, the internal layer of this laminated film is a hot sealing layer, on hot sealing layer, be coated with thin metal layer, insulating barrier is arranged on the thin metal layer, and insulating barrier is coated with mylar outward.Hot sealing layer and mylar outside all can be coated with the conduction oil film.
The anti-static shielding laminated film of multiple-structure is adopted in the utility model packaging bag, and its surperficial resistance is low, and slight electric conductivity is arranged, and has electromagnetic shielding action, can protect packaging components and parts or pcb board encroached on by the interference in extraneous electricity, magnetic field effectively.
The electrostatic prevention combined package bag has shaded effect, can allow the client know and see packaging object and sign thereof clearly, and is for confirmation.
Warning marker can be printed in the packaging bag surface, has tough and tensile intensity, good paracentesis resistance and excellent heat sealability.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment packaging bag;
Fig. 2 is the section structure partial enlarged drawing of Fig. 1 anti-static shielding laminated film.
The specific embodiment
Below in conjunction with the embodiment accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of one embodiment packaging bag.Packaging bag adopts the anti-static shielding laminated film to make, and (or left and right, limit, the ends three) heat-sealing is combined into the open package bag on its left and right both sides, and wherein 6 is open end, and 7 is left side heat-sealing line, and 8 is right heat-sealing line.During use, pcb board or responsive electronic devices and components are put into packaging bag, the heat-sealing opening gets final product.This electrostatic prevention composite shielding laminated film has shaded effect, and the client can know and sees the packaging object clearly.
Fig. 2 is the section structure partial enlarged drawing of Fig. 1 anti-static shielding laminated film.This anti-static shielding laminated film is the laminated film of four-layer structure, and its internal layer is a hot sealing layer 1, is coated with thin metal layer 2 on hot sealing layer 1, and insulating barrier 3 is arranged on the thin metal layer 2, the insulating barrier 3 outer mylars 4 that are coated with.
Hot sealing layer 1 is the film that contains polyethylene and un-stretched polypropylene, also can be distributed with antistatic additive in this film.The surface electrical resistance of heat sealing film layer is 10
8-10
9Ω, in order to being diffused in sealing bag, hot sealing layer 1 is internal layer, is folded in the inside when making packaging bag, so that add heat sealing with heat-sealing equipment.
Thin metal layer is the aluminium oxide thin layer of metallization on the heat sealing film layer.The aluminum oxide film layer thickness is 10 ц m, and its surface electrical resistance is 10
3-10
5Ω.
Insulating barrier is the PE adhesive layer, and surface of insulating layer resistance is not less than 10
12Ω is in order to preventing that the thickness direction of static charge from the sealing bag thin metal layer from flowing.
Outer mylar, the best surfaces resistance 10 of adopting
8-10
9Ω is in order to being diffused in the sealing bag outside.
The hot sealing layer of anti-static shielding laminated film shown in Figure 2 and mylar outside all are printed on the conduction oil film.
Above-mentioned thin-film material surface resistance is lower, and slight electric conductivity is arranged, and electromagnetic shielding action is arranged, can actv. the electronic devices and components of protection packaging avoid extraneous electricity, magnetic field interference and infringement.
The manufacturing process of anti-static shielding laminated film is:
1, blowing contains the film of polyethylene and un-stretched polypropylene, by vacuum coating equipment aluminium ingot is flashed to vaporificly, continuously by vacuum furnace, makes al deposition become alumina layer to the one side of film described film;
2, on the alumina deposit layer, adopt compounding machine to make PE insulated with material layer, covered with polyester film then;
3, use copperplate printing at above-mentioned film surface conductive oil again, heat, cool off again, promptly obtain this anti-static shielding laminated film through baking oven to 85-95 ℃.Wherein conductive oil contains polyethylene dioxythiophene 57.65%, Polyurethane dispersing agent 15.63%, N-methyl second pyrrolidone 3.48%, isopropyl alcohol 23.24%.
