Heat Shrinkage Tester

Film Shrinkage tester, known as free shrink tester, is used for analyzing the effect of temperature on heatshrinkable films made from polyethylene, ethylene copolymers and their mixtures.

Thermal Shrinkage Test - Oil Bath Method

The specifically sized specimen is placed into a heat transfer oil (e.g. silicone oil) at a certain temperature to be heated for shrinkage testing. After a certain period of time, the specimen is taken out, and the size of the specimen after the heating process is measured. The ratio of the dimension before and after the heating process is the shrinkage ratio. The ratio is the shrinkage of the sample.

Saicheng heat 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

GB/T 13519-2016 - Polyethylene Heat-Shrinkable Film For Packaging Applications
