Unrestrained Linear Thermal Shrinkage
Necessity of Testing
Conducting heat shrink testing is essential for ensuring product quality and performance reliability.
1.Core means of quality control
The heat shrinkage performance directly affects the dimensional stability and applicability of the material. The heat shrinkage test can monitor the changes of the material during the heating process and detect abnormalities in time.
2.Improve packaging adaptability and user experience
Whether the heat shrink film is tight and beautiful is related to the packaging quality and brand image. Testing can avoid problems such as wrinkles, warping, and breakage.
3.Meet standards compliance and market access
Heat shrink materials must comply with ASTM D2732, ISO 14616 and other standards. Heat shrink testing ensures that products meet technical requirements.
4.Promote innovation and material optimization
Thermal shrinkage test is an important means to evaluate the thermal stability of new materials, which is helpful for R&D and structural design.

Frequently asked questions
What is the main purpose of a shrinkage tester?
A shrinkage tester is used to measure the linear thermal shrinkage of plastic films and sheets when exposed to elevated temperatures. It helps assess the dimensional stability of packaging materials during heat sealing, steam sterilization, or shrink-wrapping processes. Common applications include food packaging, medical films, and industrial shrink films.
Which standards does the shrinkage test follow?
The most commonly used standard is ASTM D2732, which specifies the method for determining the unrestrained linear thermal shrinkage of plastic film and sheeting. Other related standards may include ISO 14616.
What heating media are used during the test?
Shrinkage tests can use either a temperature-controlled water bath or a hot air oven as the heating medium. Water baths are ideal for precise and uniform heating, while air ovens are suitable for materials that cannot be exposed to water.
Does the sample need to be fixed during the test?
No. According to ASTM D2732, samples should remain unrestrained during the heating process, meaning no clamping or force should be applied. This allows the sample to shrink freely and reflects its natural thermal shrinkage behavior.
