Function and Use

The SN-R hot-adhesive impact tester of Guangzhou Shounuo Scientific Instrument Co., Ltd. is used to determine the hot-adhesive strength of plastic films under different hot-adhesive temperature, pressure and time conditions.

Test Principle

The two layers of film samples are heat-sealed, and then the sample is pulled so that it is torn from the hot-adhesive part by the impact rod, and the required force value is measured to evaluate its hot-adhesive strength.

Compliant standards

ASTM F1921, ASTM F2029, QB/T 2358, YBB 00122003

Instrument features

1. LCD display to display test data.

2. Adjustable temperature, pressure and time, independent temperature control of upper and lower sealing knives.

3. Use compressed air and pneumatic drive.

4. Built-in printer to print test reports.

5. The shape, size and smoothness of the hot-adhesive cover of the sealing knife can be customized.
