At Asian Packaging Industries, every corrugated box undergoes comprehensive quality testing to ensure it meets the highest standards of strength, durability, and performance. We believe that reliable packaging begins with accurate testing, which is why our in-house quality testing laboratory evaluates both raw materials and finished products before they reach our customers.
These tests help us manufacture corrugated packaging that performs consistently during storage, handling, transportation, warehouse stacking, and export shipments.
Why Quality Testing Is Important
A corrugated box may appear strong, but without proper testing, it is impossible to determine whether it can safely protect your products.
Quality testing helps us ensure:
- Consistent packaging performance
- Better product protection
- Reduced transportation damage
- Higher stacking strength
- Compliance with customer specifications
- Reliable export packaging
- Improved customer satisfaction
Every test plays an important role in determining the overall quality of the packaging.
Quality Tests We Perform
1. GSM (Grams per Square Meter) Test
The GSM Test measures the weight of the paper used to manufacture corrugated boxes.
This test helps determine:
- Paper thickness
- Paper quality
- Material consistency
- Overall board performance
Selecting the correct GSM ensures the box has sufficient strength without increasing unnecessary packaging costs.
2. Burst Factor (BF) Test
Burst Factor measures the strength of kraft paper by determining the pressure it can withstand before bursting.
Higher BF paper provides:
- Better durability
- Increased load-bearing capacity
- Improved resistance to handling damage
This test is especially important for industrial and export packaging.
3. Bursting Strength Test
The Bursting Strength Test measures the ability of the complete corrugated board to resist rupture under pressure.
It helps evaluate:
- Board durability
- Overall paper quality
- Resistance to external pressure
This ensures the packaging remains intact during transportation.
4. Edge Crush Test (ECT)
ECT measures the edgewise compression strength of corrugated board.
This test is critical for:
- Warehouse stacking
- Vertical load-bearing capacity
- Transportation performance
Higher ECT values indicate better stacking strength and improved carton durability.
5. Box Compression Test (BCT)
The Box Compression Test evaluates the maximum load a corrugated box can withstand before collapsing.
This test helps determine:
- Stacking performance
- Warehouse storage capability
- Transportation safety
It is particularly important for heavy-duty industrial and export packaging.
6. Cobb Test
The Cobb Test measures the water absorption capacity of paper over a specified period.
This test helps determine:
- Moisture resistance
- Paper absorbency
- Suitability for humid environments
Lower Cobb values generally indicate better resistance to moisture.
7. Pin Adhesion Test
The Pin Adhesion Test measures the bonding strength between the fluted medium and linerboards.
Strong adhesion ensures:
- Better structural integrity
- Improved board strength
- Longer packaging life
8. Moisture Content Test
Moisture content significantly affects the performance of corrugated packaging.
We monitor moisture levels to ensure:
- Stable board strength
- Proper printing quality
- Better dimensional stability
- Reliable packaging performance
9. Dimensional Accuracy Inspection
Every box is checked to ensure it matches the approved dimensions.
We verify:
- Length
- Width
- Height
- Squareness
- Folding accuracy
Accurate dimensions improve product fit and reduce packaging waste.
10. Print Quality Inspection
For printed corrugated boxes, we inspect:
- Colour consistency
- Logo accuracy
- Barcode readability
- Print registration
- Coating quality
- Overall finish
This ensures your packaging looks professional and represents your brand effectively.
