Place the film sample carefully centered on the lower block with its long ends overlapping the block equally on each side.
2. Move the crosshead position until the upper block is resting on the film sample and is directly above the lower plate.
3. Carefully separate the ends of the double layer of film and peel back to the edges of the blocks on each side.
4. Tape the two ends of the upper layer of film to the upper block, and the two ends of the lower layer of the film to the lower block. Do not otherwise disturb the film or plates during this step.
5. Load the Film Blocking Method in your testing software and customize your desired report settings.
6. Start Test. As the test runs the two films will pull away from the blocks and peel apart.
7. The software will record the test results, you can continue with your samples following this same procedure. Once testing is complete the software will provide reports for more in depth analysis.
