Application The FSR-01 Shrink Force and Ratio Tester serves the purpose of measuring both the shrinking forces and shrinkage ratio of heat shrinkable films. These films are typically created through extrusion and stretching (hot drawing) during their manufacturing process, retaining this stretched state even after cooling.
When the heat shrinkable film is reheated to the temperature at which the initial stress was introduced and subsequently fixed during its production, this stress is released, causing the film to contract or "shrink back." Depending on the specific manufacturing treatment applied, the film can be categorized as either biaxially oriented (stretched in two directions) or uniaxially oriented (stretched in one direction).

Test Process
1. A well-insulated air oven is heated to the set temperature. The two samples are placed separately on two test stations, for shrinkage rate and shrink/contraction force testing.
2. A temperature probe is located to measuring area, to give result as reference temp. The air oven is driven down automatically to cover the sample area. The force and shrink rate are to be measured and the shrinkage temperature is reached when the maximum shrinking force is attained.
3. When this force has decreased by around 15%~30%, the air oven is lifted and time is recorded.
4. The assessment of shrinkage ratio is performed at the mean time.

Technical Features
1. PLC Control and HMI Touch Screen: ensuring industrial-level stability.
2. Well-Insulated Air Oven: The air oven is excellently insulated and capable of automatic lowering and lifting, enhancing the precision of the testing.
3. Non-Contact Shrink Ratio Measurement: accomplished through a noncontact method, improving accuracy and reliability.
4. Real-Time Display:including shrinking force, contracting force, and shrinkage ratio, allowing for immediate analysis and monitoring.
5. Elimination of Interference Factors: Irrelevant interference factors like friction and cool air are effectively eliminated, ensuring the accuracy of the results.
6. Stable Heating System: The heating system is stable and well-balanced, maintaining consistent and controlled test conditions.
7. Easy Sample Loading: Sample loading is made easy, streamlining the testing process and reducing setup time.
8. High-Resolution Sensors: The system is equipped with high-resolution force transducers and thermometers, guaranteeing precise measurements.
9. Connectivity and Software:(optional) It includes an RS232 port for data connectivity and offers optional professional software for advanced data analysis and reporting capabilities.

Film Shrinkage Test Equipment Film Shrinkage Tester GBK-D1
Film Shrinkage test, known as linear thermal shrink test or free shrink test, is used for analyzing the effect of temperature on heat shrinkable films made from polyethylene, ethylene copolymers and their mixtures. Basically, shrinking force, contracting force and shrinking ratio can be measured in such determination.

GBPI Film Shrinkage tester conforms to the multiple national and international standards:
ASTM D2732 - Standard Test Method for Unrestrained Linear Thermal Shrinkage of Plastic Film and Sheeting
ISO 14616 - Plastics Heatshrinkable films of polyethylene, ethylene copolymers and their mixtures Determination of
shrinkage stress and contraction stress
DIN 53369 - Testing of plastic films determination of the shrinking stress

Film Shrinkage Test Equipment GBK-D1 is used to determination of the degree of unrestrained linear thermal shrinkage and dimensional stability at different temperatures. Widely used in industries of plastic material, plastic products, petroleum, chemicals, research institute, inspection agency and so on.

Principle
This tester uses the principle of air heating to connect the tested sample to the tension sensor and displacement sensor. After reaching the maximum shrinkage force, it is placed in an external test environment with an ambient temperature of 23 to cool down.
The reference temperature, shrinkage force and displacement are recorded, and the recorded data can be used to determine the optimal shrinkage conditions of the film.
