How to deal with the corona phenomenon in the process of winding PVC printing film? The unclear Dongguan Shengyao winding PVC printed film passes between the two electrodes with high voltage. The high voltage ionizes the air between the electrodes, generates electron flow, forms oxidized polarized groups on the surface of the film, which makes the film surface more polar Printing ink adsorption.

　　 The corona treatment is simple easy to perform, the treatment effect is good. The following is a discussion on the testing control of corona treatment on BOPP processing the influence on the film performance.

     Corona treatment is a very important link in the processing of winding pet film. Usually we use corona equipment, flame treatment can also be used. Flame treatment is to use a specific blowtorch to burn a certain composition proportion of gas With air, an oxidizing flame with a temperature as high as 2100~2800℃ is formed to achieve the purpose of instantaneously changing the surface properties of the film. In the actual treatment process, the temperature of the flame, the distance between the flame the film the treatment time are important to the treatment effect. factor. Wrapped pet film is a polypropylene material. The surface tension of this material is only 31 dyne. Generally, the surface tension of the film is required to be above 38 dyne.

        Dongguan Shengyao Plastic Co., Ltd.-Protective mask transparent mask manufacturer was established in 2002 covers an area of more than 10,000 square meters. It is a professional manufacturer of PVC, PP, PET, PS films. The products are widely used in blister packaging. , Offset printing, window paste, folding boxes, hardware, toys, magnetic cards, playing card production, billboards, helmets, electronic insulation other industries, can provide customers with 17% value-added tax invoices.
