Paper Tear Strength Testing Machine

Working principle explanation of cardboard tearing strength testing machine:
Use a pendulum to tear the specimen and indicate the tear strength.

The cardboard tear strength testing machine is suitable for testing the tear resistance of plastic films, composite films, thin sheets, paper, cardboard, textiles, and non-woven fabrics. The cardboard tear strength testing machine complies with testing standards such as ISO1974 "Determination of Tear Strength of Paper and Board", GB455.1 "Determination of Tear Strength of Paper", GB455.2 "Determination of Tear Strength of Paperboard", etc.
