This standard specifies the technical specifications for coated film products using acrylic latex as the coating layer and biaxially oriented polypropylene film as the substrate. It comprehensively covers their classification, technical requirements, test methods, and inspection rules. To validate their core performance as packaging materials, the standard defines testing items primarily including optical properties (such as haze and gloss), surface properties (such as coefficient of friction), physical and mechanical properties (such as tensile strength and thermal shrinkage), and barrier properties. Correspondingly, performing these tests requires a series of specialized instruments, such as haze meters/spectrophotometers, gloss meters, friction coefficient testers, universal material testing machines, thermal shrinkage testers, and gas transmission rate testers.
