Product Description

Film Free Shrink Tester for Heat Shrinkable Plastic Film – Precision Testing for Packaging and Industrial Materials

The Film Free Shrink Tester is an advanced laboratory testing instrument designed for accurately evaluating the unrestrained thermal shrinkage properties of plastic films and sheeting. Compliant with international testing standards such as ISO 11501, ASTM D2732, and GB/T 13519, this instrument is essential for packaging manufacturers, quality inspection labs, research institutions, and food and pharmaceutical material developers.

This high-precision instrument simulates thermal environments to measure how plastic films shrink without external constraints, providing key data on thermal stability, material performance, and product consistency. Whether you are working with shrink wraps, heat-sealed films, or multilayer flexible packaging, the Film Free Shrink Tester ensures reliable and repeatable shrinkage analysis across a wide temperature range.


What is a Film Free Shrink Tester?

The Film Free Shrink Tester is a specialized laboratory device used to test the free shrinkage behavior of plastic films when exposed to elevated temperatures. Unlike tensile or restrained shrink testing, this test measures the film’s ability to shrink freely in a fluid medium, without applying any mechanical stress. This test is particularly valuable in evaluating films used in shrink packaging, food wrapping, pharmaceutical blister packs, and industrial flexible films.

By immersing the film specimen in a uniformly heated fluid bath, the Film Free Shrink Tester allows operators to observe and quantify how much the material shrinks in two dimensions—length and width—at specific temperatures.
