Background
Good cling adhesion of the stretch film can make the outer packaging film layer and the layer of the goods stick together, so that the goods on pellets will become very firm. The application field of stretch film is very wide, and the quality control of peel cling can effectively improve the toughness, elasticity and supporting force of the film. Testing peel cling requires preparing two different types of samples. The first sample is larger and acts as a substrate or backing. The second piece is a smaller strip which is peeled off of the larger sample.
Application
SPC-01 Peel Cling Tester measures cling between two layers of film and help to determine the property of stretch wrap material ability to adhere to it.
Technical Features
It’s a PLC controlled unit (industrial level stable) and HMI touch screen operated. Precision ball lead screw mechanism ensures good and steady speed and displacement control.
- 7 inch TFT touch screen operation (human machine interface)
- PLC control unit inside for stable performance
- Precision ball screw for accurate speed & displacement.
- Test speed is adjustable.
- Different connection of loadcell with sample eliminates the interference caused by the friction and gravity of pulley and string, which are commonly used in traditional method.
- Limiting device and automatic returning.
- Real time display of test curve, peak value recording.
- Supportive lines of elongation rates, 50%, 100% and 200%.
- Microprinter
- Coefficient of friction function can be added (Optional)

Standard
ASTM D5458 Standard Test Method for Peel Cling of Stretch Wrap describes a way to measure the adhesion strength between two layers of film, so as to know which of the two layers (external or internal) can adhere with greater or lesser strength.
