    Paperboard Testing Machine

    Overview Knowledge Standards Terms
    The cardboard testing machine applies pressure to cardboard through mechanical or hydraulic devices to measure its performance, such as compressive strength, burst strength, and ring crush strength. It is used to evaluate the load-bearing capacity of cardboard during transportation and stacking, and is widely applied in quality control of packaging materials and product research and development.
    Selection
    When selecting, it is essential to match the required range and accuracy of the testing standards, and consider the compatibility of the specimen size with the fixture. Pay attention to the parallelism of the pressure plates and the stability of speed control, and choose between manual or automatic models based on the testing frequency. Confirm whether the data output interface meets the laboratory recording requirements, and ensure regular calibration and maintenance.

    Transverse Burst Strength Tester for the Evaluation of Impact Resistance of Corrugated Cardboard
    This article explains how a lateral bursting strength tester is used to evaluate the impact resistance of corrugated cardboard. It measures the energy absorbed by the cardboard at the point of rupture using the pendulum impact principle, requiring the preparation of specimens according to standards and the control of environmental conditions during testing.
    Short Span Compression Strength (SCT) Tester for Analyzing Paper Compression Resistance
    The short-span compressive strength (SCT) tester is used to measure the resistance of materials such as paper and cardboard to compression over a short distance, primarily following international standards such as ISO 9895.
    The Taber stiffness tester is used for measuring the bending stiffness of paperboard.
    The Taber stiffness tester is used to measure the bending stiffness of paperboard. Its principle involves applying a known bending moment to the specimen and measuring its resistance to deformation. Bending stiffness is a key performance indicator of paperboard, affecting its processing suitability and packaging functionality.
    Application of Paperboard Burst Strength Tester in Packaging Materials
    The paperboard bursting strength tester is a detection device used to measure the ability of packaging materials such as paperboard to resist rupture under vertical pressure. During the test, the sample is clamped between annular clamps, and increasing pressure is applied via hydraulic or pneumatic means until rupture occurs. The maximum pressure value is recorded as the bursting strength.
    Cobb Absorbency Tester Evaluates Paper Water Absorption Capacity
    The Cobb water absorption tester is used to measure the water absorption capacity of paper or cardboard by simulating the liquid contact process and calculating the mass of water absorbed per unit area to determine the Cobb value.
    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.
    Selection Guide for Paperboard Puncture Strength Testers
