Abstract
The utility model discloses a stabbing-resistant and anti-static shielding film and is to solve the technical problem that electronic products, such as high-precision electronic products, sensitive electronic devices, high-precision circuit boards and the like, are interfered by environmental static or electromagnetic waves and then damaged in the packaging and transportation process because packaging film materials are stabbed. The stabbing-resistant and anti-static shielding film comprises a composite film with a PET substrate inside, and the composite film also comprises a functional layer formed by extruding stabbing-resistant and anti-static nylon and thermoplastic resin together. Compared with the prior art, as the functional layer formed by extruding the stabbing-resistant and anti-static nylon and the thermoplastic resin together is also additionally arranged in the stabbing-resistant and anti-static shielding film, when used for packaging the electronic products, the stabbing-resistant and anti-static shielding film can prevent pins at all tips of the electronic products or pointed objects outside packaging bodies from stabbing and destroying the composite film so as to ensure that the electronic products are not damaged in the packaging and transportation process; and besides, with the protection of two anti-static coatings, the safety of the electronic products in the storage process and the transportation process can be further improved.

Background technology
21 century, all trades and professions are all in electronization, and the electronic product development rapidly.The structure of electronic product and spare and accessory parts thereof and performance are more and more accurate.In its manufacturing, transportation, use, the process of circulation, receive the infringement of extraneous static and electromagnetic wave etc. easily, make the reduction of electronic devices and components precision, signal parameter drift, shorten the life-span or make product failure fully.Static discharge ESD (English full name: Electro-Static discharge; Chinese: static discharges) and Electromagnetic Interference EMI more and more serious to the influence of high-accuracy electronic product, responsive electronic devices and components, high-accuracy circuit board etc., become ubiquitous a kind of danger at present.Common antistatic shielding product is puncture not, and packaging product lets anti-static shielding lose efficacy to the scuffing puncture of shielding material etc. easily, and product is exposed in static and the electromagnetic wave environment.
Summary of the invention
The purpose of the utility model provides a kind of puncture anti-static shielding film; The technical problem that solves is to avoid electronic products such as high-accuracy electronic product, responsive electronic devices and components and high-accuracy circuit board in the packed and transported process, because of the packaging film material be punctured receive environment static or Electromagnetic Interference impaired.
The technical scheme that the utility model adopts is:
The puncture anti-static shielding film of the utility model, it is the composite membrane that comprises PET basic unit, also includes the functional layer that is co-extruded by puncture Antistatic Nylon and thermoplastic resin in this composite membrane.
The composite membrane of the utility model is formed by four layers; Constitute by aluminum plated PET basic unit, described functional layer and anti-static coating respectively; Adopt the gluing resin compounded between the end face of aluminum plated PET basic unit bottom surface and described functional layer, be coated with anti-static coating respectively at the end face of aluminum plated PET basic unit and the bottom surface of functional layer.
The composite membrane of the utility model also can be formed by five layers; Constitute by PET basic unit, metal aluminum foil layer, described functional layer and anti-static coating respectively; Adopt the gluing resin compounded between the end face of the bottom surface of aluminum plated PET basic unit and metal aluminum foil layer; Adopt the gluing resin compounded between the bottom surface of metal aluminum foil layer and the end face of said functional layer, be coated with anti-static coating respectively at the end face of aluminum plated PET basic unit and the bottom surface of functional layer.
Thermoplastic resin described in the utility model is a polyethylene.
Thermoplastic resin described in the utility model also can be polypropylene.
The utility model is compared with prior art owing to increased the structure of a kind of puncture Antistatic Nylon and polyethylene or polypropylene co-extrusion functional layer again in the anti-static shielding film; Make when electronic products such as high-accuracy electronic product, responsive electronic devices and components and high-accuracy circuit board being packed with it; Can resist the outer sharp object of each most advanced and sophisticated pin in the said electronic product or package body destroys its puncture; Not therefore thereby guaranteed that said electronic product can be in the packed and transported process and damaged; Adopt the protection of two-layer anti-static coating up and down in addition; More effective anti-static shielding has further improved the security of said electronic product in keeping and transportation.
