Anti-static blister tray

1.Test method of anti-static blister tray

Purpose: In the field of blister packaging, in order to ensure that electronic products are not burned by static electricity after packaging, the packaging materials must have anti-static or conductive functions. Suitable for testing Products: PVC/PET/PP/PS anti-static, electronic anti-static tray, vacuum blister tray Test instrument: anti-static tester

Test standard: ACL-380 adopts ASTM standard D-257 parallel electrode sensing method, which can easily and repeatedly measure various conductive, electrostatic discharge and insulating surfaces.
Use: To measure surface impedance, place the tester on the surface to be tested on the blister tray or electronic blister tray, press and hold the red TEST button, the light-emitting diode (LED) that lights up continuously indicates the measured value. Surface impedance magnitude.

  1. Material selection
    At present, according to the antistatic value, it is divided into: conductive, semiconductive and antistatic. Since the conductive effect is the best, conductive and semi-conductive materials are slightly more expensive than antistatic ones.
    Conductivity: The index is 3-5 power, and it can be guaranteed for 1 to 3 years.
    Semi-conductive: The index is 6-8 power, which can be kept valid for 6 months to 1 year.
    Anti-static: 9-11 power, effective within 6 months.
    The materials involved are: PET/PS, PVC 3 kinds, but PVC can not be made into conductive effect, the other 2 kinds can.
    Colors are: PVC/PET can be made into transparent and various other colors, PS cannot be made into high-transparency.
    Anti-static processing method: According to the material properties, it is divided into external coating and internal coating.
    External coating: When the sheet is produced, a layer of anti-static liquid is applied on the surface of the material to achieve the effect of anti-static. (PET materials are generally coated by external coating).

Internal addition: Use the anti-static or conductive raw materials that have been added to directly pull into a blister sheet without adding anti-static liquid. (PVC, PS materials are generally added).
