Aluminum plastic film warping experiment test method

The invention discloses an aluminum-plastic film warping experimental test method, and relates to the technical field of aluminum-plastic tests.The method comprises the following steps that firstly, when an aluminum-plastic film sample sheet is put into a humidity box, the aluminum-plastic film sample sheet is prevented from making contact with silica gel or a saturated aluminum sulfate solution; 2, four A4 sample pages are cut out, the center point of the bottom of the aluminum plastic film sample page is fixed to a table top through an adhesive tape, and a 300 mm cross line is marked along the two diagonal lines of the sample; and 3, observing the conditions of the two marked diagonal lines, measuring the warping height by using a ruler, and measuring the warping heights in the upper, lower, left and right directions by using a vernier caliper, thereby being beneficial to intuitively and accurately measuring the warping change of the aluminum-plastic film, further being beneficial to judging the service lif
