Cooking class CPP film thickness is generally between 60 ~ 80 μ m packing plastic film production, the ability of 121 ℃, 30 min of high-temperature cooking food packaging plastic film standard, oil resistance, better beef airtight plastic film packaging, and high heat seal strength plastic film packaging, general packaging lining are made of meat cooking class CPP film. Aluminum film is currently the most widely used primary aluminum film aluminized polyester (VMPET) and CPP aluminized (VMCPP). Of course, corona treatment should be moderate, not a corona treatment intensity the higher the better. It is worth noting that between the plastic film and the corona treatment roll folder into the air should be avoided, or has the potential to reverse the film is also a corona treatment. Corona cause negative consequences are: 1 may produce anti-sticking ink; 2 when aluminum aluminum layer transfer occurs, occurs when the adhesive coating layer transfer plastic film packaging bags, plastic film packaging Xianyang Hongqi Hongqi Plastic Factory Xiongxian plastics plant by.
