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.

Background
Plastic films and sheets are typically made by melting polymer material and then shaping it through processes like extrusion or calendaring. During this production, the material is stretched in the machine direction, and as it cools, some internal stresses remain. When reheated, these stresses can cause the material to shrink, altering its dimensions.
This shrinkage is crucial for quality and process control in plastic manufacturing.
It helps assess process consistency, adjust production parameters, and understand material characteristics. Industries like packaging rely on shrinkage data to ensure precise fit after heat exposure.
In essence, shrinkage is a key factor in maintaining product quality and process efficiency in plastic film and sheet production.
Application
The FST-01 Film Free Shrink Tester is used to measure the unrestrained linear thermal shrinkage of plastic film and sheets at specified temperatures in a fluid medium. This device helps assess how much these materials will shrink when exposed to heat in real-world applications.
Test Process
1. Temperature Setup and Stabilization: Set the temperature on PID controller and the fluid is heated to a preset temperature and temperature is stabilized.
2. Specimen Preparation and Submersion: Mount the test specimen into the free shrink holder. Submerge them together into the liquid bath.
3. Time Monitoring and Completion: The timer starts to count down and when the test time is reached, an alarm will beep, signaling the end of the test.
4. Test Conclusion: Carefully remove the test specimen from the liquid bath. Press the Stop button on the tester to mark the conclusion of the test.
5. Shrinkage Measurement and Assessment: Treat test specimen in ambient environment and Measure the linear shrinkage of the specimen.
Calculation
To calculate the unrestrained linear shrinkage percentage using the given formula:
Unrestrained Linear Shrinkage (%) = [(Lo - Lf) / Lo] x 100
Where:
Lo = Initial length (100 mm)
Lf = Length of the side after shrinking
