Abstract

The invention discloses a cigarette film shrinkage rate testing method, device and equipment and a readable storage medium. The method comprises the steps of marking two parallel straight lines spacedby a preset distance on a cut to-be-detected film; measuring the actual distance between the two parallel straight lines, and recording the actual distance as a first distance value; controlling theto-be-detected film to vertically fall to a position in contact with the soldering iron and stay for a preset time, and preheating the soldering iron to a preset temperature; controlling the to-be-detected film to leave the position in contact with the soldering iron, measuring the actual distance between the two parallel straight lines again, and recording the actual distance as a second distancevalue; and calculating the shrinkage rate of the to-be-detected film according to a shrinkage rate calculation formula: shrinkage rate = (the second distance value-the first distance value) / 100. According to the invention, the technical problems of unreliable test result and low practicability of the existing method for testing the shrinkage rate of the cigarette film are solved.

Description

technical field [0001] The present application relates to the technical field of film performance testing, in particular to a method, device, equipment and readable storage medium for testing the shrinkage rate of a cigarette film. Background technique [0002] Cigarette packaging film, usually BOPP cigarette film, is co-extruded and stretched from various polypropylene functional materials. At present, domestic manufacturers generally use three-layer (A / B / C) co-extrusion technology to produce high-performance BOPP cigarette film through biaxial stretching, which has high transparency and gloss, non-toxic materials, stable molecular structure, and is resistant to odor and moisture. It has a certain barrier function, so it is an ideal material for cigarette packaging. [0003] The shrinkage rate of cigarette film is related to the shape and dimensional accuracy of the product, and has an important impact on the aesthetic performance of flexible packaging. Too tight shrinkag...
