Electrostatic charges in film production arise primarily from the following causes:Electrostatic Generation During Film ProductionStatic electricity is generated during film production due to friction between polymer particles, friction between the melt and the die, and friction between the formed f

As friction in film production is unavoidable, static electricity affects production in the following main aspects: Printing DifficultiesDue to (minor static discharge), burrs or fluffy (whisker-like) ink overflow often appear at the edges of printed patterns. Static electricity charges the ink,

The rapid development of biaxial stretching technology has brought revolutionary changes to the flexible packaging market. There are three main development directions for global biaxial stretching technology. First, ordinary packaging products will place greater emphasis on low cost and high efficie

A casting machine, also known as an extender, is a mechanical device used to form a highly uniform film, sheet, or foil-like material on a metal surface. It usually consists of a rolling mechanism, a stretching mechanism, a coating mechanism, a cutting mechanism and other parts.The principle of the
