The invention belongs to the technical field of polypropylene film production, and discloses a polypropylene film standard sample with a plasticizer migration value and a production method. First, mix the plasticizer and some polypropylene resin raw materials evenly, and then extrude the master batch; then mix the master batch and the remaining polypropylene resin raw materials according to a set ratio, blow the film to obtain a polypropylene film, and carry out the Standard samples were obtained after the series of treatments. The prepared polypropylene standard samples have good uniformity and stability, and can be used for the comparison of the detection data of the plasticizer migration value in the polypropylene film between the laboratories, the accuracy of the verification method, the calibration of the test instrument and the quality of the test results. control and assessment. |
