Carton Stiffness Tester

The carton stiffness tester measures the bending resistance of paperboard using the three-point bending method. The sample is placed between two supports, and a central indenter presses down at a constant speed until fracture occurs, with the maximum force value recorded. It is used to evaluate the compressive strength and stacking stability of cartons, guiding packaging design and quality control.
Selection
Select the corresponding range based on common cardboard thickness, typically choosing 5-500 mN·m. Ensure compliance with GB/T 2679.3 or ISO 5628 standards. Prioritize models with automatic calibration and consider the adjustable range of testing speed. Check the wear resistance of the indenter and fulcrum materials, and confirm that the data interface is compatible with the existing system.

Key Operation Points of Carton Burst Strength Tester
The carton bursting strength tester is used to measure the maximum force that paperboard can withstand before rupturing under uniform pressure, which is important for packaging quality control. Before operation, ensure that the instrument is stable and the calibration is valid. The samples should be cut according to standards and conditioned under standard temperature and humidity conditions.
Application of Carton Compression Testing Machine in Transportation Packaging Testing
The carton compression tester is primarily used to evaluate the load-bearing capacity of transport packaging under compressive forces. It simulates the pressure experienced by cartons during stacking or transportation using upper and lower compression plates, recording the relationship between pressure and deformation until the carton collapses or reaches a preset value.
Application of Compression Strength Testers in Carton and Paper Tube Testing
The compression strength tester evaluates the compressive performance of cartons and paper tubes by applying controlled pressure and measuring deformation.
The role of a bending stiffness tester in evaluating the rigidity and formability of cardboard.
The bending stiffness tester evaluates the rigidity and formability of cardboard by measuring its resistance to bending deformation. Based on the beam bending theory, it is tested under standard conditions, providing bending stiffness value as the core indicator.
