Working Principle of Corrugated Box Compressive Strength Tester

Corrugated Box Compressive Strength Tester adopts a servo motor to drive the transmission system. It operates through ball screw pressure. The high-precision force sensor accurately reflects the load status of the test piece. The microcomputer system collects and processes the test parameters, and outputs and displays the test results.

Brief Introduction

Corrugated Box Compressive Strength Tester PBT-01 is designed for compression and stacking test for pack aging containers, anti-corrugated boxes, paper tube, paper tubes, plastic containers etc. Box compression tester have several test modes including compressive strength test, fixed value test, stacking test etc.

Calculation method of carton compression strength

The strength standard of corrugated boxes, GB6543 national standard Appendix A stipulates: the compression strength value P of corrugated boxes should not be less than the value calculated by the following formula: P=K·G(H-h/h·s)(kgf/cm2)

In the formula: K- factor of strength insurance;

G-Weight of cargo in corrugated box, kgf

H-stacking height, cm

h-box height, cm

S-box bottom area cm2

This formula can be simplified in practice as: P=K·G(n-1)

In the formula: n-stacking layer number

K-according to the storage time

<30 days 1.6, 30-100 days 1.65, more than 100 days 2

But some data set it as 3, so the safety factor is greater

If a certain instant noodle box has a gross weight of 3.5kg and a stack of 16 layers, the strength (pressure resistance, the same below) standard of the corrugated box should be:
