Product instruction

Film Shrinkage test, known as linear thermal shrink test or free shrink test, is used for analyzing the effect of temperature on heat shrinkable films made from polyethylene, ethylene copolymers and their mixtures. Basically, shrinking force, contracting force and shrinking ratio can be measured in such determination.
GBPI Film Shrinkage tester conforms to the multiple national and international standards:
* ASTM D2732 - Standard Test Method for Unrestrained Linear Thermal Shrinkage of Plastic Film and Sheeting
* ISO 14616 - Plastics -- Heatshrinkable films of polyethylene, ethylene copolymers and their mixtures -- Determination of
shrinkage stress and contraction stress
* DIN 53369 - Testing of plastic films -- determination of the shrinking stress

Film Shrinkage Test Equipment is used to determination of the degree of unrestrained linear thermal shrinkage and dimensional stability at different temperatures. Widely used in industries of plastic material, plastic products, petroleum, chemicals, research institute, inspection agency and so on.
