carton compressive strength testing machine HD-A501-1200

Product catalog summary

Overview: The document discusses the importance of compressive strength in cartons, particularly for those at the bottom of a stack during storage and transportation. It introduces the carton compressive strength tester, a machine used to evaluate the compression performance of various packaging materials.

Equipment Use: The carton compression tester is designed for testing the compression, deformation, and stacking capabilities of corrugated and honeycomb boxes, as well as other containers like plastic barrels and paper cans.

Main Factors Affecting Compressive Strength:

Relative Humidity: As atmospheric humidity increases, the moisture content in corrugated boxes rises, reducing compressive strength. For example, at 95% humidity, compressive strength drops to 40%.
Printing Area: Full-page printing can reduce compression resistance by about 40%.
Horizontal Ribbon Printing: Depending on the width and position, compression resistance can decrease by 30-37%.
Stacking Method: The strongest stacking method is flush stacking, but it may lead to instability if the carton is long.
Transportation and Handling: Shock and vibration during transport can reduce strength by up to 10%.
Accumulated Days: Long-term storage under load causes fatigue, reducing strength over time.
Box Shape: The A-5 shape offers the best compressive strength.
Hand Hole Influence: Larger hand holes and those near edges reduce strength.
Size Influence: Larger peripheral lengths increase strength, with optimal width being 0.6 times the length for maximum strength.

Carton compressive strength testing machine 9 common senses that affect the compressive strength of cartons The carton is required to have a certain compressive strength, because the carton stacked on the lowest layer is subjected to the pressure of the upper carton during the storage and transportation process after packaging the goods. In order not to collapse, it must have a suitable compressive strength. The instrument for testing the compressive strength of the carton is called the carton compressive strength tester. Equipment use: The carton compression tester is a professional testing machine for testing the compression performance of cartons, suitable for compression, deformation and stacking tests of corrugated boxes, honeycomb boxes and other packaging.

take into account the compression test of plastic barrels (edible oil, mineral water), paper barrels, cartons, paper cans, container barrels (IBC barrels) and other containers. Generally speaking, the main factors that affect the compressive strength are as follows: 1. Relative humidity The moisture content of corrugated boxes increases or decreases with the increase or decrease of atmospheric humidity, and the compressive strength of corrugated boxes increases or decreases with the increase or decrease of moisture. Relative humidity Moisture content Compressive strength 50% 2. Printing area...

5. Transportation and handling During transportation, the corrugated box is subjected to shock and vibration, which makes the carton easy to fatigue and thus affects the strength of the carton. Multiple loading and unloading may cause a decrease in compressive strength, but the influence of these two factors is small, within 10%. 6. The influence of accumulated days The long-term accumulation and storage of cartons under load will cause fatigue, and the compressive strength of cartons will gradually decrease.
