Surface protection films are specially designed to prevent any type of abrasion, scratches during the manufacturing process and also prevent damage during the delivery cycle. A good protective film can easily withstand the pressure in the manufacturing process, such as cutting, deep drawing, bending, and the user's mechanical handling effects during manufacturing and transportation. When the protective film is removed, the quality of the substrate remains the same as when it left the factory. But these functions are only provided by high-quality adhesive materials.
In order to test the quality and peel ability of the film, a Presto peel strength Tester is required for testing. This machine is an efficient testing instrument that quantifies the peel strength of bonded materials. It checks the durability of the stick or peel ability of self-adhesive and pressure-sensitive materials. The machine is designed according to the international testing standard of ASTM D 903. This means that the machine follows global testing methods. It is equipped with highly proficient load cells responsible for applying an equal amount of peel pressure to the specimen over the entire surface.
Specially designed powerful clamps are suitable for fixing specimens of different sizes and shapes. Safety limit switches limit stroke length when performing peel tests. It helps the user to set the stroke length according to industry standards. Features a digital display based on a microprocessor program that is highly integrated and professional. Maintain higher precision of test values. Has a default 180-degree fixture for testing at this angle. 90 degree clamps are available upon request. The machine allows users to calibrate the settings according to their requirements using the built-in calibration function.
