Types of Films Tested

The Film Free Shrink Tester is suitable for a wide range of films, including packaging materials, food packaging films, medical device packaging, pharmaceutical packaging, adhesive films, and textiles. Each type of film has specific characteristics that need to be evaluated to ensure optimal performance.

(2) ASTM D2732 Standard

Description of the Standard

ASTM D2732 is a standardized test method used to measure the free shrinkage of plastic films when exposed to a specified temperature. This standard provides a consistent framework for conducting the test, ensuring that results are comparable across different laboratories and applications.

Test Procedure Outline

Sample Preparation

Samples are cut to a precise size and shape, typically squares or rectangles. Proper preparation is essential to ensure that the results are accurate and reflective of the material’s properties.

Testing Conditions

The test involves heating the samples to a predetermined temperature. The Film Free Shrink Tester’s precise temperature control ensures that the samples are exposed to the exact conditions required by ASTM D2732.

Measurement and Analysis

After heating, the samples are measured to determine the extent of shrinkage. The dimensions before and after the test are compared to calculate the percentage of shrinkage. This data provides insights into the film’s thermal behavior and suitability for specific applications.

4. Industry Applications

The Film Free Shrink Tester is essential for various industries, each with unique requirements for material performance.

(1) Packaging Materials

In the packaging industry, the film shrinkage test helps in designing materials that offer optimal protection and stability. Understanding how films respond to heat ensures that packaging maintains its integrity during processing and storage.

(2) Food Packaging Films

For food packaging, maintaining the quality and safety of the product is paramount. The heat shrinkage test ensures that films used in food packaging are durable and can withstand the conditions they will encounter.

(3) Medical Device Packaging

Medical device packaging requires materials that are both protective and sterile. The film shrinkage test helps in selecting films that meet these stringent requirements, ensuring the safety and effectiveness of medical products.

(4) Pharmaceutical Packaging
