Paper Packaging Testing

Product Introduction

The tearing strength tester is used to measure the tear resistance of various types of paper and paperboard. It is designed based on the Elmendorf tearing principle. It is also applicable for testing tear‑resistant performance of plastic films, composite films, thin sheets, textiles and non‑woven fabrics.
