The main testing items for polyethylene blown agricultural films include size measurement, appearance quality measurement, mechanical performance measurement, and weather resistance measurement. The size measurement mainly detects indicators such as thickness and thickness deviation, width limit deviation, net mass limit deviation, etc. Appearance quality refers to the detection of defects such as bubbles, impurities, stripes, perforations, wrinkles, and the quality of film rolls. The mechanical performance testing items include tensile load, nominal fracture strain, right angle tear load, and other indicators. The weathering performance requires testing the nominal strain retention rate index for longitudinal fracture after aging P> Function of testing report:1.
