Description
Technical field
The utility model relates to a kind of electron membrane, relates in particular to the structure of this electron membrane.
Background technology
External industrially developed country fully realized electrostatic hazard is existing in the sixties, had formulated a large amount of antistatic packaging standards in succession.Antistatic packaging material also develops rapidly thereupon, has controlled the harm of static effectively.Show in the industry that the electronic product reliability improves constantly, increase in amplitude the service life of electronic device, and military inflammable explosive article blast accident greatly reduces.Domestic also had understanding to the harm of static in recent years, and performance has generally been noticed Electrostatic protection in process of production.
The world today has been the information age, and the electromagnetic wave of various frequencies, wavelength is full of spherical space entirely.These electromagnetic waves cause data distortion to producing interference in various degree without the sensitiveness electronic component that shields, circuit board, computer, communications service etc., and communication is disorderly.And the electrion of the static that electromagnetic induction and friction produce to producing because of accumulation of static electricity between various sensitiveness electronic components, instrument and meter, production area etc., its consequence will be destructive, or even catastrophic.
Antistatic protection the most effectively, reliable solution is exactly the anti-static shielding bag; The anti-static shielding bag is according to " faraday cup " principle design, and its particular structure can form responds to article and electrostatic field isolation in the cover effect protection bag, prevents accumulation of static electricity; Avoid electrostatic hazard; Be applicable to the packing of electrostatic sensitive products such as PCB (printed circuit board (PCB)), IC,, prevent that the device of adorning from suffering static and electromagnetic destruction to guarantee article and electrostatic field isolation in the bag; Thereby the electrostatic sensitive electronic devices and components in the protection bag are avoided electrostatic hazard to greatest extent, and the anti-static shielding bag is first choice of the antistatic packaging bag.
Most critical, most crucial part are exactly the electron membrane of utilizing the little coating technology in the vacuum metallization processes coating technique to produce in the antistatic packaging.The raw material that this metallization electron membrane the most often adopts are biaxially oriented polyester film (being called for short BOPET), and what the metallization coating material was the most frequently used is fine aluminium.But the electron membrane of producing in this way, color have only blueness or two kinds of grey partially, can't produce other color, are pursuing product diversification, personalized today, and seeming, some does not catch up with trend.
Summary of the invention
The utility model technical issues that need to address have provided and a kind ofly outer have been coated with color vacuum aluminum plated PET electron membrane, are intended to solve the above problems.
