Shrinkage Tester for Plastic Films – Accurate Thermal Shrinkage Analysis for Packaging, Food, and Medical Applications
The Shrinkage Tester is an advanced laboratory instrument specifically designed for evaluating the thermal shrinkage characteristics of plastic films and flexible sheet materials. Commonly used in packaging, food processing, medical, and beverage industries, this device plays a critical role in ensuring the dimensional stability and heat resistance of materials when exposed to elevated temperatures.
This Shrinkage Tester complies with internationally recognized standards such as ISO 11501, ASTM D2732, and GB/T 13519, which define procedures for measuring the free shrinkage of plastic films in a fluid medium. It accurately determines the unrestrained linear shrinkage of films at various temperatures, offering reliable data for quality control, research, and product development.
Why Thermal Shrinkage Testing Is Important
Plastic films, especially those used in shrink packaging and food wraps, must maintain specific physical properties during processing and use. If the film shrinks excessively or inconsistently when exposed to heat, it may compromise packaging performance, shelf life, and visual appeal. A Shrinkage Tester provides critical information about how a material behaves under thermal stress, which is essential for:
-
Packaging line optimization
-
Material formulation improvements
-
Product development and innovation
-
Regulatory and compliance assurance
Key Features of the Shrinkage Tester
The ISO 11501 Film Free Shrinkage Tester comes equipped with features tailored for precision, repeatability, and user safety in laboratory environments. These features make it suitable for diverse industrial sectors that rely on thin plastic films for product protection and presentation.
1. Advanced P.I.D. Temperature Control
Ensures precise and stable temperature settings, reducing error margins in test results. This high-level control mechanism allows consistent thermal environments during the shrinkage test.
2. High-Precision Timer
Allows accurate timing for thermal exposure, which is crucial when testing film shrinkage over specific durations to determine consistency and performance under real-world conditions.
3. Integrated Alarm Function
The instrument includes an automatic alarm system that alerts users to operational anomalies, over-temperature events, or testing completion, ensuring safe and efficient use in laboratories.
4. Uniform Heating System
The fluid medium heating system ensures stable, even heat distribution throughout the chamber, minimizing temperature fluctuations and providing reliable, reproducible test outcomes.
5. Standardized Sample Clamping Mechanism
Features a standardized square metal clamp and free shrink holder, designed to fix the film sample in place without causing mechanical distortion, ensuring accurate shrinkage measurement.
