Abstract
The utility model discloses an antistatic film capable of shielding electromagnetic waves. The antistatic film comprises a surface layer, a PET (polyethylene terephthalate) middle layer and a bottom layer which are orderly arranged from top to bottom, wherein an antistatic layer covers the surface of the bottom layer; the bottom layer is made of PET materials; and the material of the surface layer is the PET material. The antistatic film capable of shielding electromagnetic waves has the beneficial effects that the antistatic layer is formed by forming an extremely thin conductive layer on the surface of a thin film and forming a continuous phase, so that the surface conductive performance is improved, the generated charges can be leaked as quickly as possible, the outside static electricity is effectively prevented from damaging the packaged products, the packaged products are protected, and the potential safety hazard is eliminated. Simultaneously, the antistatic film has a function of shielding electromagnetic waves.
Description
Technical field
The utility model relates to a kind of antistatic film, particularly the electromagnetic antistatic film of a kind of shielding.
Background technology
The PET film is the more comprehensive packing film of Performance Ratio.Its transparency is good, and is glossy; Have good air-tightness and fragrance protectiveness; Moisture resistance is medium, and rate of perviousness descends at low temperatures.The mechanical performance of PET film is good, and its obdurability is best in all thermoplastics, and tensile strength and impact strength are more much higher than general film; And deflection is good, and dimensionally stable is suitable for the secondary operations such as printing, paper bag.The PET film also has good heat-resisting, cold resistance and good chemical proofing and oil resistivity, but it does not have antistatic property, static on the products such as packaged sensitiveness electronic component, circuit board, communication equipment in time can not be removed, be had larger potential safety hazard.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of surface conductance performance strong, the electromagnetic antistatic film of shielding that the charge energy of generation is leaked as early as possible.
To achieve these goals, technical solution adopted in the utility model is: the electromagnetic antistatic film of a kind of shielding, comprise the surface layer, PET intermediate layer and the bottom that are arranged in order from top to bottom, and described bottom surface is coated with antistatic layer.
Bottom is the PET material.
The material of surface layer is the PET material.
The beneficial effects of the utility model are: shield electromagnetic antistatic film; its antistatic layer is to form one deck conductive layer as thin as a wafer at film surface; and formation continuous phase; improve the surface conductance performance; the electric charge of generation is leaked as early as possible; effectively prevent the damage of extraneous static to packaged product, protected packaged product, eliminated potential safety hazard.Has simultaneously the electromagnetic function of shielding.
Description of drawings
Fig. 1 is the section structure schematic diagram that the utility model shields electromagnetic antistatic film.
The specific embodiment
Referring to Fig. 1, the electromagnetic antistatic film of a kind of shielding that the utility model relates to, it comprises PET surface layer 1, PET intermediate layer 2, PET bottom 3 and the antistatic layer 4 that sets gradually; Described PET surface layer 1, PET intermediate layer 2 and the PET bottom 3 three-layer co-extruded films of making; Also can add the PET feed back in the PET intermediate layer 2.
The PET bottom 3 surface spraying antistatic coatings of the film of coextrusion form antistatic layer 4.During use; then antistatic layer 4 surperficial glue coated at the electromagnetic antistatic film of shielding are fitted on the packaged product, and the electric charge that product surface is produced leaks as early as possible; effectively prevent the damage of extraneous static to packaged product, effectively protected packaged product.
Claims (3)
1. the electromagnetic antistatic film of shielding comprises the surface layer (1), PET intermediate layer (2) and the bottom (3) that are arranged in order from top to bottom, and it is characterized in that: described bottom (3) surface coverage has antistatic layer (4).
2. the electromagnetic antistatic film of shielding as claimed in claim 1 is characterized in that, bottom (3) is the PET material.
3. the electromagnetic antistatic film of shielding as claimed in claim 1 is characterized in that, the material of surface layer (1) is the PET material.
