Best ISO 14616 and DIN 53369 Compliant Shrinkage ratio and shrink force tester Thermal shrink ratio and foce measurement

The FSR-01 Film Shrinkage Tester is a precision instrument designed for laboratories and quality control departments to evaluate the shrinkage force and shrinkage ratio of heat shrinkable films. Fully compliant with ISO 14616 and DIN 53369 standards, this tester ensures reliable, repeatable, and accurate measurement results that manufacturers across the packaging, food, beverage, medical, and pharmaceutical industries depend on to guarantee film performance.

As a DIN 53369 shrink force tester, the FSR-01 is engineered for comprehensive shrinkage testing of plastic films. Heat shrinkable packaging films are widely used in shrink-wrapped products, tamper-evident seals, bottle labeling, and protective wraps. Understanding their shrinkage force and shrinkage ratio under controlled thermal conditions is essential for ensuring consistency, durability, and quality in the final application.

Why Choose a DIN 53369 Shrink Force Tester?

The shrinkage behavior of films directly impacts product safety, sealing reliability, and shelf appeal. The DIN 53369 shrink force tester provides critical data on:

• Shrink Force Measurement – The contraction force generated by films when reheated to their stress-induced temperature.

• Shrinkage Ratio Analysis – The extent to which the film shrinks, either biaxially or uniaxially, depending on its manufacturing process.

• Thermal Performance Validation – Ensuring that heat shrinkable films meet packaging requirements under real-world conditions.

Manufacturers who rely on the FSR-01 tester can optimize film formulations, ensure compliance with international standards, and reduce risks associated with packaging failures.

Principle of Operation

During production, shrink films are stretched and cooled under stress. When reheated, these films contract back toward their original dimensions, generating measurable forces. The FSR-01 DIN 53369 shrink force tester replicates this process with controlled precision:

1. The air oven is pre-heated to the target temperature.

2. Two specimens are mounted—one for shrinkage ratio testing, one for shrink force testing.

3. A probe measures the reference temperature at the sample location.

4. The oven is automatically lowered to cover the sample area.

5. Shrinkage force and shrinkage ratio are continuously recorded in real time.

6. The shrinkage temperature is identified at the peak force value.

7. When force decreases by 15–30%, the oven is raised and testing time is documented.

8. Shrinkage ratio is calculated at the mean time interval.

This systematic method eliminates operator errors and delivers consistent, reproducible data for film evaluation.
