Plastic film surface treatment methods are: corona treatment, chemical treatment, mechanical roughening method, a coating method, which is most commonly used corona treatment method. The basic principle of corona treatment law: by applying a high-frequency, high-voltage power between the metal electrode and the corona treatment roll (usually high temperature, ozone resistance, high dielectric silicone rubber rollers), thus producing a discharge, thus causing air ionization and the formation of ozone. Cooking class CPP film thickness is generally between 60 ~ 80 μ m opp plastic film, the ability of 121 ℃, 30 min of high-temperature cooking plastic film prices, oil resistance, better air tightness and high heat seal strength, general It is used in cooking meat packing inner class CPP film. Aluminum film is currently the most widely used primary aluminum film aluminized polyester (VMPET) and CPP aluminized (VMCPP).
