The Film Free Shrink Tester is a precision instrument used to measure the unrestrained linear thermal shrinkage of plastic films and sheeting under controlled temperature conditions. Compliant with ASTM D2732, ISO 11501, and GB/T 13519 standards, this tester is ideal for packaging material manufacturers, quality control laboratories, research institutions, and academic testing facilities. The device provides a reliable solution for assessing how films behave when exposed to heat, without the influence of external mechanical constraints—an essential factor in packaging, labeling, and food preservation applications.
