Main parameters of computer bending stiffness tester

2025/02/11

Computer bending stiffness tester is a test equipment independently developed and produced by our company. It has high-cost performance and is used to test the bending stiffness of composite sheet materials such as paper, cardboard, film, plastic, metal sheet, etc. It is suitable for the papermaking packaging printing industry-related scientific research institutions and quality inspection departments.

As a modern technology enterprise integrating R&D, manufacturing, sales, training, and services, Standard International Group (HK) Limited is committed to delivering more testing instruments to the market, providing testing instruments for textiles, leather, combustion, automotive interior and exterior trims, material environmental climate aging, etc., and non-standard customization is also acceptable. Targeted tests can be carried out according to customer requirements before purchase to ensure that the purchased instruments are applicable.

Scope of application:

Stiffness value test: Applicable to bending stiffness test of paper, cardboard, film, plastic film, and sheet

Crease stiffness test: Applicable to the crease and indentation stiffness test of various color boxes, toothpaste boxes, and other packaging boxes

Compliance with standards:

GB/T 22364, GB/T 2679.3 "Stiffness test of paper and cardboard," ISO 249.3 "Determination of stiffness of paper and cardboard," ISO 5628 "Paper and paperboard - Determination of static bending stiffness - General principles"
