Seal Press Tester

When evaluating workability, including embossing fitness, of paper for crepe paper, towel paper, etc., conventional press-based equipment has drawbacks in that pressure or temperature cannot be set meticulously. With this tester, embossing fitness of specimens can be evaluated against the seal strength needed for paper towel's wrap-around seal section, for example, or for coffee filter's sealed section on the edges. Also, this tester enables to identify the required strength by applying different pressure, temperature and humidity settings and checking the behavior of the sealed sections. To serve the above purpose, the tester incorporates a pressurizing bar with a set of concave and convex-shaped teeth members and a large-sized air cylinder to press the bar down on the specimen. It can operate with a pressure up to 6300 kg and a heating temperature up to 150 °C. In addition, a safety mechanism is employed to allow pressurizing operation to take place only when the operator uses both hands to press the start switch.
