ISO 2493 5628 Paper Cardboard Crease Stiffness Testing Machine Paperboard Tensile Strength Tester
Instroduction
The paper and board crease stiffness tester is used to measure the bending stiffness of various types of paper, paperboard, films, plastics, metal sheets and other composite sheet-like materials. It is applicable to the paper-making, packaging, printing industries, as well as related research institutions and quality inspection departments.
Tensile strength test: Applicable for testing the bending tensile strength of paper, cardboard, film, plastic film and thin sheets.
Crease stiffness test: Applicable for testing the crease indentation stiffness of various packaging boxes such as color boxes and toothpaste boxes.
Compliant with standards
