Box Compression Tester vs. Other Packaging Strength Tests: A Comparison

Testing for packaging strength is important for industries such as logistics, e-commerce, food, and pharmaceutical. There are various methods through which performance of boxes and containers could be evaluated based on the operating conditions. Manufacturers will be able to reduce damage to products at delivery time, maintain standards, and optimize their packaging processes.

Among the different tests for packaging strength, the Box Compression Tester is unique, it provides an important measure of the compressive strength of boxes. In contrast to other packaging tests, the BCT emphasizes a box's resistance to vertical loads, making it especially suited to assessing stacking strength when the product is stored and shipped.

This blog will discuss Box Compression Tester, comparison of BCT with other common tests in packaging, and hence help industries choose the proper test for their requirements.

What is a Box Compression Tester?

A box compression tester is an extremely specialized piece of equipment used to test the compressive strength of corrugated boxes, among other packaging. It reveals the weight, a box can bear before being crushed or collapsing by its weight.

This test applies an even, vertical force upon the box until it bends or fails. This gives manufacturers information regarding the load-carrying capacity of a box under stacking, in transit, or storage.

The box compression test is specifically used for industries dealing with huge shipments or products that are supposed to be stacked without any pressure and do not collapse.

Comparison: Box Compression Tester vs. Other Packaging Stacks tests

Measurement Focus

Compression Test: Tests how much vertical load a fully assembled box can withstand on stackability.

Other Tests

• Edge Crush test: Measures the edgewise compression strength of corrugated materials.
• Burst Test Strength: Tests resistance to bursting against the internal uniform pressure.
• Drop test: Impact Strength of boxes in free-fall.

Sustained Application

Box Compression Tester (BCT): Suitable for determining a box's stability and stacking strength in storage and during transport.

Other Tests:

• ECT: Suitable for determining the edge strength of the corrugated board.
• Bursting Strength Test: Suitable for boxes, exposed to uniform external pressure.
• Drop Test: Suitable for packages that are handled or dropped repeatedly.

Testing Procedure

BCT: Exerts a uniform vertical force on the box until it crushes or is distorted.

Other Tests: 

• Include specific tests such as puncturing, tensile pull, or edge pressure.

Precision and Data Output

BCT: Offers the load-carrying capacity in kilograms (kg) or Newtons (N), thus giving practical information on stacking limits.

Other Tests: 

• Edge strength, burst resistance, or impact performance are important for specific material properties.

Choose the Right Test for Your Needs

Determine which packaging strength test suits your product, material content, and shipping requirements:

• Stackability: Use box compression to find out how much it can handle in terms of vertical loading capacity.
• Together, the Edge Crush Test and Bursting Strength Test may be conducted on corrugated materials as an indication of material strength.
• For Handling Scenarios: Drop Test and Puncture Resistance Test shall be conducted to simulate the conditions of rough handling.

Industries usually combine BCT with other packaging tests for a more robust quality assurance strategy because several strength evaluations need to be made.

Formula to Calculate Compressive Strength

The compressive strength CS of a box can be determined using the formula:

Where:

• CS = Compressive Strength (N/mm² or kg/cm²)
• F = Maximum Force applied (N or kg)
• A = Cross-sectional Area (mm² or cm²)

This formula helps determine the load-bearing capacity of the box, aiding in quality control and material optimization.

FAQs

1. Which industries is the Box Compression Test most useful for?

The logistics, e-commerce, food, pharmaceutical, and manufacturing industries rely on BCT to ensure that the strength of packaging is assured.

2. Can the Box Compression Test be combined with any other tests?

Yes, integrating BCT with ECT tests, bursting strength tests, or drop tests provides an in-depth assessment of packaging performance.

3. How does BCT minimize packaging costs?

By ensuring the right amount of strength, BCT prevents over-designing boxes, hence not using much material, resulting in lower costs.
