To measure the compression strength of copy paper boxes, a Box Compression Tester is used. Copy paper boxes are typically made of B flute board and have side panels of the bottom tray oriented with the board MD in the vertical direction. This can lead to buckling and product failure over time due to the axial load created by stacking.

The Box Compression Tester, such as the Box Compression Tester Box Compression Tester-Digital by Pacorr, is designed to accurately measure the compression strength of cardboard boxes, ensuring they resist deformation during transit loading and storage stacking conditions. The machine complies with testing standards such as ASTM D642, ASTM D4169, TAPPI T804, ISO 12048, and JIS Z0212. It measures the yield strength, proportional limit, and compression strength of the boxes.

Here are some features of the Box Compression Tester:

Microprocessor-based bright LED display: Provides live test result analysis and accurate output.

Uniform compression force: Ensures precise calculations during the test.

TARE and peak hold facility: Allows for easy measurement and recording of test results.

Over-travel protection: Safeguards the instrument during the test.

Strong base plate with a rugged structure: Minimizes external movements during testing.

Feather touch controls: Provides an advanced user-friendly experience.
