Abstract
The utility model provides an anti-static composite environment-friendly packaging thin film, which comprises four layers, namely a heat-seal layer, a thin metal layer, an insulating layer and a mylar layer from the inside out. Conductive oil films are arranged outside the heat-seal layer and the polyester membrane layer. The thin film has low surface resistance value, strong electrostatic discharge property, and electromagnetic shielding effect, and can effectively prevent electromagnetic field effects of electrostatic discharge such as electromagnetic interference and electromagnetic compatibility from interfering and damaging the packaging components or printed circuit boards.
Description
Technical field
The utility model belongs to field of packaging material, relates in particular to a kind of electrostatic prevention compound environment-friendly package film.
Background technology
At present, the packing of electronic devices and components and printed circuit board adopts the common plastics bag more.Use the common plastics bag,, be easy to generate static, cause the inner somewhere of packaged product rest potential to increase, thereby produce spark discharge, have influence on the safety of goods because of having high-insulativity under the influence in the mutual friction of device phase, bump, external electrical field and magnetic field.Though also have the similar packing of electrostatic prevention to occur, technically, they are to realize by the savings that slows down static, and the material that production process is taked causes environmental pollution easily.Therefore, when selecting and use packing, satisfying under original engineering factor requirement, adopting the low conductive material of electrical resistivity to come the dangerous goods in packaged form goods, can prevent that the static savings from playing the effect of protection cargo security.
Summary of the invention
The purpose of this utility model is the problems referred to above at the packing existence of existing electronic devices and components and printed circuit board, provides a kind of static savings that prevents to play the electrostatic prevention compound environment-friendly package film of protection packaged product safety effect.
The purpose of this utility model is achieved in that the utility model comprises four-layer structure, is hot sealing layer, thin metal layer, insulating barrier, polyester film layer from the inside to the outside successively, is equipped with the conduction oil film in the outside of described hot sealing layer and polyester film layer.
As preferred version, the consisting of of described conduction oil film: ethanol 99%, ethanol ether 0.5%, neopelex 0.5%, in weight percentage.
As preferred version, described hot sealing layer is the film that contains polyethylene and un-stretched polypropylene, and thin metal layer is the aluminium oxide thin layer of metallization on hot sealing layer, and insulating barrier is a polyethylene layer.
Reach throught voltage is less than 50V less than 2.0S the utility model electrostatic attenuation time as can be known by following test method, and penetrating capacity is less than 50nJ:
1, the test method of ASTMF150-1998 conduction and electrostatic dissipation type resilient floor resistance;
2, the heat sealable elasticity electrostatic prevention of GJB 2605-1996 barrier material standard;
3, ANSI/ESD S20.20-2007 Electrical and Electronic device, assembling and equipment protection, electrostatic discharge control outline.
Technique effect of the present utility model is: the utility model is the laminated film of multiple-structure, its surperficial resistance is low, electrostatic discharge is stronger, and have electromagnetic shielding action, can effectively prevent the interference infringement of the Electromagnetic Environmental Effect of electrostatic discharge such as electromagnetic interference and emc issue to packaging components and parts or pcb board.The utility model is mainly used in products such as packing pcb board and electronic devices and components.
Description of drawings
Fig. 1 is the Facad structure scheme drawing that has adopted the packaging bag of the utility model membraneous material.
Fig. 2 is the section structure partial enlarged drawing of the membraneous material of packaging bag employing shown in Figure 1.
The specific embodiment
Referring to Fig. 1, packaging bag adopts two-layer electrostatic prevention compound environment-friendly package film to make, and double-layer films is at the left and right both sides of packaging bag heat sealing, and the upper and lower end of packaging bag is an open end, and 5 is left side heat-sealing line, and 6 is right heat-sealing line.During use, pcb board or responsive products such as electronic devices and components are put in the packaging bag, get final product at upper and lower side heat-sealing mouth then.Packing film of the present utility model has shaded effect, and the client can know and sees the packaging object clearly.
Referring to Fig. 2, packing film comprises four-layer structure, is hot sealing layer 1, thin metal layer 2, insulating barrier 3, polyester film layer 4 from the inside to the outside successively, all is printed on the conduction oil film in the outside of hot sealing layer 1 and polyester film layer 4.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 hot sealing layer 1 is 10
8-10
9Ω is beneficial to static and is diffused in the sealing bags outside, and hot sealing layer 1 is an internal layer, is folded in inner face when making packaging bag, so that add heat sealing with heat-sealing equipment.Thin metal layer 2 is metallization aluminium oxide thin layers on hot sealing layer 1, and the aluminum oxide film layer thickness is 10um, and its surface electrical resistance is 10
3-10
5Ω.Insulating barrier 3 is the polyethylene glue adhesive layer, and the surface electrical resistance of insulating barrier 3 is not less than 10
12Ω flows from the thickness direction of sealing bags thin metal layer 2 to prevent static charge.Polyester film layer 4 is outer, and surface electrical resistance is 10
8-10
9Ω is best, is beneficial to static and is diffused in the sealing bags outside.Consisting of of conduction oil film: ethanol 99%, ethanol ether 0.5%, neopelex 0.5%, in weight percentage.The surface electrical resistance of above-mentioned packing film material is lower, and slight electric conductivity is arranged, and electromagnetic shielding action is arranged, and the electronic devices and components of energy actv. protection packaging etc. are avoided the interference and the infringement in extraneous electricity, magnetic field.
The manufacturing process of electrostatic prevention compound environment-friendly package film shown in Figure 2 is as follows:
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 the aluminium oxide thin layer to the one side of film the described film that contains polyethylene and un-stretched polypropylene;
2, on the aluminium oxide thin layer, adopt compounding machine to make PE insulated with material layer, covered with polyester film then;
3, again conductive oil is used the surfaces externally and internally of copperplate printing, heated, cool off again, promptly obtain electrostatic prevention compound environment-friendly package film through baking oven to 85-95 ℃ at previous step gained laminated film.
