In the anti-static technology of flexible packaging, the electrical insulation of plastic materials is very good, but static electricity is easily generated during processing and use. Foreign matter such as hair and film adhesion can easily lead to quality problems. Therefore, antistatic treatment of flexible packaging is very important. The current development of plastic film anti-static hanging more. For example, oxidize with a strong chlorinating agent or treat the surface of the film with corona discharge. ?
Additive treatment technology Adds an antistatic agent to a thermoplastic resin at a certain concentration and adds a variety of additives. After being melted, mixed, and granulated, an antistatic masterbatch is prepared, and an antistatic masterbatch is used to prepare an antistatic agent. plastic film.
Coating-type processing technology makes ionic surfactants into antistatic coatings that are applied to the surface of plastic films to prevent charge accumulation. Polyurethane adhesives can be used as carriers, dissolved in solvent-based plastic coatings with ester solvents to make antistatic coatings. According to reports, the anti-static technology has solved the difficulties in the production process of flexible packaging manufacturers and can improve the quality of products.
