1 blown film machine specifications and deviations The width and thickness of the polyethylene film should meet the requirements, the thickness of the film is uniform, the thickness deviation in the longitudinal direction and the transverse direction is small, and the deviation distribution is relatively uniform. 2 blown film appearance It is required that the polyethylene film is plasticized well, no obvious fish eyes, the film surface is smooth and smooth, no wrinkles, no bubbles, cracking phenomenon, no obvious black spots, impurities, and no hanging diagonal lines and silk lines are allowed. 3 blown film machine physical and mechanical properties Since the blown polyethylene film is subjected to mechanical force during printing or composite processing, the physical and mechanical properties of the polyethylene film are required to be excellent, mainly including tensile strength, elongation at break, tearing. Several indicators such as strength meet the criteria.
