First understand the basic properties of the underlying shielding bag material. Anti-static shielding bag material structure APET/CPP (semi-aluminized film/polypropylene casting film) has good transparency, hard, good hand feeling, weak tearing force, good heat sealability, good tearing, strong pulling force, and feel Soft two, the overall color is silver-gray translucent, the built-in objects are visible. The unique structure of the anti-static shielding bag can form the induction cover effect to protect the contents of the bag from the electrostatic field, prevent static electricity accumulation and protect against static electricity, and is the first choice for anti-static packaging bags.
The anti-static shielding bag making method is the same as the aluminum foil bag nylon bag. The difference is that the material property of the anti-static shielding bag cannot be equal to the vacuum bag. Although there is a pressure-sealed heat seal, such materials will slowly leak at the crimp seal under the pressure of inflation or pumping, thereby damaging the performance of the bag. Some customers will take the shielding bag for "vacuum" treatment. In a strict sense, it should not be called vacuum. Just take a little out of the air inside the bag, so that there is no obvious feeling of inflation when the air is sealed. It is far from the degree of vacuuming. Because the air pressure is small, there is no obvious pressure on the inside of the bag. It can be done. Such processing. If the product needs to be treated in real vacuum and has anti-static performance of anti-static shielding bag, it is recommended to use anti-static aluminum foil bag. The aluminum foil bag material can ensure the customer's product has comprehensive anti-static effect, and can achieve absolute vacuum. effect
