Characteristics of PVC printed film. PVC printing film is generally made by blow molding casting. The thickness of cast polyethylene PVC film is uniform, but due to its high price, it is currently rarely used. Blow molded polyethylene PVC film is made by blowing PE particles through a blow molding machine. Low cost, therefore the most widely used.

Low density polyethylene PVC film is a semi transparent, glossy, soft PVC film with excellent chemical stability, heat sealing, water resistance, moisture resistance, freezing resistance, boiling water resistance. Its main drawback is poor oxygen barrier. It is often used as the inner layer PVC film for composite flexible packaging materials, is also one of the most commonly used PVC films in plastic packaging, accounting for about the consumption of PVC films in plastic packaging. More than 40%. 

Due to the presence of polar groups in polyethylene molecules, high crystallinity, low surface free energy, poor printing performance of PVC film, poor adhesion to ink adhesives, lamination should be used before printing. Surface treatment is required.
