Film Shrink Force And Ratio Tester ASTM ISO 14616 DIN 53369 Shrinking Force Contracting Force And Shrinkage Ratio Test

The FSR-01 Film Shrink Force and Ratio Tester, also known as a DIN 53369 Shrinking Force Tester, is a specialized laboratory instrument designed for the accurate measurement of shrink force, contracting force, and shrinkage ratio in heat-shrinkable films. This instrument is widely used in the packaging, food, pharmaceutical, beverage, and materials research industries, where heat-shrinkable films are essential for product integrity, sealing, and protection.

By meeting international testing standards such as DIN 53369 and ISO 14616, the FSR-01 ensures reliable and repeatable results that support both R&D and quality control processes. It is an advanced solution for manufacturers, converters, and research institutions seeking to evaluate shrink film performance with scientific precision.

Why Choose the DIN 53369 Shrinking Force Tester?

Heat-shrinkable films play a vital role in modern packaging, offering secure product wrapping, tamper resistance, and enhanced product presentation. However, their mechanical behavior under heat must be thoroughly understood to ensure consistent performance.

The DIN 53369 Shrinking Force Tester provides a comprehensive solution by simulating controlled heating environments and accurately recording the mechanical response of films during shrinkage. Unlike conventional testers, this instrument integrates high-resolution sensors, PLC-based controls, and automated reporting to deliver precise data while eliminating operator errors and environmental interferences.

Key advantages include:

• Multi-sample testing efficiency: Three test groups (6 samples) can be tested simultaneously, significantly increasing laboratory productivity.

• Advanced measurement capabilities: Real-time monitoring of shrink force, contracting force, and shrinkage ratio.

• Stable heating environment: Uniform and balanced heating system ensures test repeatability.

• High precision: Force accuracy of ±0.2% and displacement accuracy of ±0.1 mm.

• User-friendly operation: Touch screen interface with intuitive PLC control.

Applications in Industry

The FSR-01 is not just a testing machine—it is an essential tool for industries where film performance directly affects product quality and customer satisfaction.

1. Packaging Industry

• Ensures consistent shrink wrap quality for food, beverages, cosmetics, and daily consumer goods.

• Evaluates shrink films used for tamper-evident seals.

2. Food & Beverage Industry

• Tests shrink films used in bottles, cans, and carton multipacks.

• Verifies uniform shrink force to prevent package deformation.

3. Pharmaceutical Industry

• Confirms film stability for medical packaging, blister packs, and protective wrappings.

• Validates compliance with stringent packaging safety standards.

4. Research and Development

• Supports academic research in materials science.

• Enables comparative studies of shrink films under different thermal environments.

Benefits of Using a DIN 53369 Shrinking Force Tester

• Improved product quality: Manufacturers can optimize film formulations for better shrink characteristics.

• Reduced packaging failures: Early detection of insufficient shrink force prevents costly recalls.

• Cost savings: Efficient multi-sample testing reduces labor and resource usage.

• Regulatory compliance: Testing aligned with DIN 53369 and ISO 14616 standards ensures acceptance in international markets.

• Data-driven insights: Automated reporting provides traceable and verifiable records.

How the Test Works

The DIN 53369 Shrinking Force Tester works by exposing film specimens to a controlled heating environment. As the material shrinks, the tester measures:

• Shrinking Force: The tensile force generated during shrinkage.

• Contracting Force: The mechanical response exerted on the restrained specimen.

• Shrinkage Ratio: The relative reduction in length or dimension.

All data are displayed in real time on the touch screen interface, allowing immediate interpretation. This enables laboratories to understand material performance characteristics under different thermal conditions.

Compliance with International Standards

Standards are critical in ensuring consistent and comparable results. The FSR-01 complies with:

• DIN 53369 Shrinking Force Tester Method – Standard procedure for measuring shrink force and shrinkage ratio in plastic films.

• ISO 14616 – Defines test procedures for evaluating shrink film behavior under thermal stress.

By adhering to these international standards, the FSR-01 provides confidence in results, whether for internal quality assurance or third-party certification.
