Basic principles of plastic film biaxial stretching process The basic principle of the biaxial stretching process is to heat and melt the polymer raw materials through the extruder and extrude them into thick sheets. In an appropriate temperature range above the glass transition temperature and below the melting point, the polymer material is heated and melted by an external force through a longitudinal drawing machine and a transverse drawing machine. Under the influence, it is stretched by a...
Solution to corona breakdown film Corona breakdown of films is a common phenomenon that can be solved by: Corona discharge treatment. This is a common method that uses a corona discharge on the surface of the film to increase the affinity of the film surface, making it more receptive to printing inks, adhesives or decorative coatings. During the treatment process, the polymer material passes between the electrodes and the sensing roller. When the applied voltage reaches the breakdown voltage of...
