To ensure packaging can withstand real-world conditions, Pacorr offers the Box Compression Tester—a high-performance instrument that measures the compressive strength of corrugated boxes.
From reducing product damage to optimizing material use, this equipment is a valuable asset for manufacturers, packaging engineers, and quality assurance teams.
What is a Box Compression Tester?
A Box Compression Tester is a laboratory-grade machine used to determine how much vertical force a corrugated box can withstand before it deforms or collapses. The device simulates the stacking conditions that boxes face during shipping and storage, providing a quantifiable value known as Box Compression Strength (BCS).
This test helps businesses assess the durability of packaging and ensure their products reach customers safely and intact.
Why is Box Compression Testing Necessary?
In industries like e-commerce, logistics, food and beverage, and pharmaceuticals, boxes are frequently stacked during transit and warehousing. Weak boxes may buckle under pressure, leading to:
Damaged products
Increased return rates
Higher shipping losses
Negative customer experiences
Additional packaging costs
By performing compression testing with a reliable instrument like Pacorr’s, companies can:
Define safe stacking limits
Choose appropriate board grades and flute types
Prevent over-packaging and reduce material waste
Maintain consistent quality across production lines
Ensure compliance with international packaging standards

How Does the Box Compression Tester Work?
The machine operates by applying a controlled vertical load to a test box placed between two compression platens. As the upper platen presses down:
The box begins to resist the applied pressure.
Compression continues until the box collapses or reaches a set load threshold.
The maximum load sustained by the box before failure is recorded as the Box Compression Strength (BCS).
This method effectively replicates how boxes behave under real stacking conditions, providing reliable insights for packaging performance.
Step-by-Step Testing Process
Select a test sample – Use an unused, undamaged box.
Position the box – Center it between the compression platens.
Input test parameters – Set the compression rate, max load, and stop conditions.
Start the test – The machine begins compressing the box.
Observe and record – The peak load value is captured and displayed.
Analyze results – Use the BCS data to validate or revise packaging design.
The entire process is quick, efficient, and easy to perform.
Industries That Use Pacorr’s Box Compression Tester
This testing equipment is applicable across a wide range of sectors, including:

Understanding Box Compression Strength (BCS)
Box Compression Strength (BCS) is the peak force a box can sustain before structural failure. This value, typically expressed in kilograms (kg) or Newtons (N), is essential for:
Designing stackable packaging
Choosing the right board material
Reducing the risk of box collapse
Improving the efficiency of shipping layouts
Enhancing packaging sustainability by using just the right amount of material
