Description

Technical Field

[0001] The invention relates to testing equipment, in particular to a comprehensive testing device for carton and paperboard properties. Background Art

[0002] Cartons are important industrial products used to package, protect and transport items. The quality of cartons is directly related to the stability of the packaged items, as well as the safety and efficiency of transportation. In order to ensure that carton products meet relevant standards and customer needs, and to ensure the safety and stability of products, various forms of inspections are required for carton products.

[0003] In the prior art, the inspection of cartons mainly includes compressive strength test, tensile strength test, bursting strength test, thickness test, etc. Among them, the most common tests are compressive strength test and bursting strength test.
