The Difference between Anti-static Shielding Bag and Packaging Bag
Feb. 18, 2020
There are many types of packaging bags, and many customers cannot distinguish the difference between anti-static shielding bags and aluminized bags. Here, Anti-static Shielding Bag Supplier summarizes a few concise differences, I hope to help everyone.
Aluminized bags apply high-purity metal aluminum to plastic film under vacuum. Because it is coated on plastic, metal aluminum only plays a decorative role and does not help much to improve the barrier properties of the material. Printed aluminized bag is a type of Anti-static Aluminum Foil Bag. The surface of the bag can be printed with LOGO patterns and text according to customer requirements. Its material structure uses VMPET / CPE (fully aluminized film / polyethylene film). Good tearing, strong pulling force, softer feel, overall color is silver opaque, high brightness, built-in objects are not visible. Can also be made into a variety of styles: flat pocket type, self-sealing type (compact bag / zipper bag), envelope type, envelope self-adhesive type, one-piece type, three-dimensional type and so on.
Anti-static Shielding Bag
Anti-static Shielding Bag is pressed by high temperature. The material structure APET / CPP (semi-aluminum film / polypropylene cast film) has good transparency, harder, feels better, and the tear force is weaker. APET / CPE (semi-aluminum film) / Polyethylene film) good heat-sealability, good tear, strong tensile force, softer feel, the overall color is silver-gray translucent, and the built-in objects are visible. Very thin thickness, it can be broken by lightly pressing it with your hands. It just looks weak and weak, but when it is combined with other plastics, the effect is great. Its barrier properties, thermal insulation and fragrance retention will be great. Of improvement.
It is distinguished by the touch of the hand. The anti-static bag is thick and wide, harder and heavier, but the aluminized bag is light and soft. Crease, the former will have obvious creases, while the latter will spring back to its original shape. The difference between anti-static shielding bags and packaging bags and the principle of static electricity
According to the Gauss theorem of the electrostatic field, the electric field line of the electrostatic field starts from positive charge or infinity, and ends at negative charge or infinity. Therefore, the electrostatic field is an active field. According to the Ampere Loop theorem, it is a spin-free field. According to the loop theorem, the loop quantity in the electrostatic field is always equal to zero, which indicates that the charges move along any closed path in the electrostatic field and the work done by the electric field force is zero, so the electrostatic field is a conservative field.
According to Coulomb's law, the force between two point charges is proportional to the product of their charge amounts and inversely proportional to the square of their distance. The direction of the force is on their line. We can create it through the ionizer. With trillions of ions, the ionizer uses a high voltage to generate a balanced mixed charged ion, and uses a fan to help the ions drift to an object or area to neutralize it. Ionization can neutralize the static charge on the insulators in eight seconds, thus reducing their potential damage. Since ionization is not a substitute for grounding or isolation, ionization only reduces the possibility or risk of electrostatic discharge accidents
Since grounding and isolation will not release charge from insulators such as synthetic cloth or conventional plastic, neutralization is important. Neutralization or removal of the electrical charges naturally generated during the process from the insulator is called ionization. Ions are simply charged substances that exist in the air. Ions are produced by natural energy substances. They include sunlight, lighting, open flames and radiation.
