Shrinkage Testing

Film Shrinkage test, known as linear thermal shrink test or free shrink test, is used for analyzing the effect of temperature on heatshrinkable films made from polyethylene, ethylene copolymers and their mixtures. Basically, shrinking force, contracting force and shrinking ratio can be measured in such determination.

Labthink 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
  • ...
