A corrugated box may look simple from the outside, but its ability to protect products depends on precise engineering and rigorous quality control. Even small variations in paper quality, moisture content, adhesive bonding, or board strength can affect packaging performance during transportation and storage.
At Asian Packaging Industries, we believe quality cannot be inspected only after production—it must be built into every stage of manufacturing. That is why we operate a fully equipped in-house quality testing laboratory, where every batch of raw materials and finished packaging undergoes comprehensive testing before reaching our customers.
This commitment to quality helps businesses reduce product damage, improve logistics efficiency, lower packaging costs, and maintain customer confidence.
Why Quality Testing Matters
Packaging failures can be expensive.
A weak corrugated box can lead to:
- Damaged products
- Customer complaints
- Product returns
- Delayed deliveries
- Financial losses
- Reduced brand reputation
These problems often cost far more than the packaging itself.
Quality testing ensures that every corrugated box performs exactly as intended throughout the supply chain.
Our Quality Philosophy
At Asian Packaging Industries, quality is not limited to the final inspection.
It begins with:
- Raw material selection
- Manufacturing process control
- Machine calibration
- Continuous monitoring
- Laboratory testing
- Final inspection
This systematic approach ensures consistency from the first box to the last.
Our Fully Equipped Quality Laboratory
Our in-house laboratory is designed to evaluate every critical property of corrugated packaging.
We test:
- Paper quality
- Corrugated board strength
- Compression performance
- Moisture resistance
- Adhesive bonding
- Dimensional accuracy
- Print quality
Every test helps us verify that the packaging meets customer specifications and industry standards.
1. GSM (Grammage) Test
The GSM Test measures the weight of paper per square meter.
Why it matters:
- Confirms paper quality
- Ensures consistent material usage
- Prevents under-specification
- Maintains packaging strength
Customers receive packaging manufactured with the correct paper grade every time.
2. Burst Factor (BF) Test
The Burst Factor Test measures the paper's resistance to rupture under pressure.
Benefits:
- Stronger cartons
- Better puncture resistance
- Reliable transportation performance
High BF paper provides greater durability during handling and shipping.
3. Bursting Strength Test
The Bursting Strength Test evaluates the overall strength of the corrugated board.
This test helps ensure:
- Better product protection
- Improved packaging durability
- Consistent board quality
4. Edge Crush Test (ECT)
One of the most important tests for corrugated packaging.
ECT measures how much vertical load a corrugated board can withstand before collapsing.
Benefits include:
- Better warehouse stacking
- Stronger cartons
- Improved pallet performance
- Safer transportation
High ECT values result in better stacking strength.
5. Box Compression Test (BCT)
The BCT measures how much weight a completed corrugated box can safely support.
This is especially important for:
- Warehouse storage
- Export shipments
- Long-distance transportation
- Heavy industrial packaging
Proper compression strength reduces carton collapse and product damage.
6. Cobb Test
The Cobb Test measures the water absorption characteristics of paper.
Why it matters:
- Better moisture resistance
- Improved export packaging
- Reduced paper weakening
This is particularly important for humid climates and sea shipments.
7. Moisture Content Test
Paper naturally absorbs moisture from the environment.
Excess moisture can reduce packaging strength.
Our Moisture Content Test helps ensure:
- Consistent paper performance
- Better compression strength
- Stable packaging quality
8. Pin Adhesion Test
The strength of the bond between liners and fluting is critical.
The Pin Adhesion Test evaluates:
- Adhesive quality
- Board integrity
- Manufacturing consistency
Strong bonding improves the structural performance of corrugated boards.
9. Dimensional Accuracy Inspection
Every corrugated box is checked for:
- Length
- Width
- Height
- Creasing accuracy
- Folding precision
Accurate dimensions ensure efficient packing and reliable product protection.
10. Print Quality Inspection
For printed packaging, we verify:
- Colour consistency
- Registration accuracy
- Barcode readability
- Print sharpness
- Overall appearance
This helps customers maintain a professional brand image.
