Abstract
The invention relates to an antistatic EPE foaming film. The antistatic EPE foaming film comprises the following components: 90 to 95 portions of carriers, 0.5 to 2.0 portions of antistatic master batches, 1 to 3 portions of lubricant, 1 to 2 portions of auxiliary agent and colored master batches; the preparation process comprises the steps of mixing resin carriers, an antistatic agent, a colored pigment master batches, french chalk and distilled glycerin monostearate according to the formula dosage; extruding and plasticizing according to the conventional method; then conducting cooling and shaping on the film; conducting corona treatment and dry lamination after dissection; and compounding other base materials or films together after conducting rubber roll pressurization on the composite surface of the manufactured antistatic film, thereby preparing double-layered antistatic air cushion film with different functions. The antistatic EPE foaming film has low content of antistatic agent, no toxic material exists, and the manufactured product can be applied to the packages of products such as electronic elements.
Description
technical field [0001] The invention relates to an antistatic EPE foam film, which belongs to the field of packaging materials. Background technique [0002] The industry has special requirements for packaging materials used to package electronic products, because during the storage and transportation of electronic products, friction and impact between components and the influence of external electric and magnetic fields are prone to generate static electricity, which makes the internal static electricity of electronic components The potential increases, thereby affecting its quality, and in severe cases, an explosion occurs. Since the 1980s, the state has successively promulgated and improved various anti-static regulations, stipulating the highest resistance value for products involving electrostatic hazards. [0003] EPE, also known as pearl cotton, is a high-foamed polyethylene product produced by physical foaming and extrusion of high-pressure low-density polyethylene ...
