Decrypt the mechanism of corona discharge treatment of PET film Source: Protective film factory direct sales Release time: 2019-07-29 Click: 1564 We have studied the surface/interface of PET film after corona treatment. Many polar functional groups will be generated on the surface of the PET film after corona treatment, which increases the polarity of the film surface and helps to improve its adhesion performance. After corona treatment on the surface of the PET film, strong polar groups such as epoxy, carboxyl, and phenolic hydroxyl groups are generated. It is the appearance of these new functional groups that give the film surface excellent adhesion and printability. Foshan Bowei Environmental Protection Material Co., Ltd. is an electronic material supplier with 20 years of experience. It can produce PET film with various functions, such as: sub-(matte) PET film, flame-retardant (fire-resistant) PET film, inkjet printing Film, anti-static PET film, anti-fog PET film, anti-UV PET film, non-shrinking PET film, PET release film, optical PET film, etc. Interested parties welcome to inquire!
