Water activated composite tape is quickly becoming the industry favourite for sealing heavy, bulky, export-grade or high-value cartons. If standard kraft paper or even reinforced water activated tapes aren’t giving your shipments the strength you need, composite WAT is the next-level upgrade built for industrial reliability.
This type of tape is engineered with layered paper, high-tensile fibreglass threads, and a water-activated adhesive that fuses directly with carton fibres resulting in a seal that’s nearly impossible to break without damaging the box. If you ship anything heavy, fragile, or sensitive, this tape is exactly what your packaging workflow has been missing.
What Is Water Activated Composite Tape?
Water activated composite tape (also called composite reinforced gummed tape) is a multi-layer kraft tape enhanced with:
- fibreglass or polyester reinforcement
- multi-ply kraft paper
- dense starch-based water activated adhesive
- cross-weave or tri-weave reinforcement patterns
The result is a hybrid-strength sealing tape designed for extreme durability. When moistened, the adhesive bonds deeply into carton fibres, creating a tamper-evident, permanent seal.
If sustainability matters, composite tape still maintains a significantly lower environmental footprint than plastic tapes.

Why Water Activated Composite Tape Is So Popular
Businesses choose water activated composite tape because it provides the highest level of sealing integrity for industrial needs. Here’s why it stands out:
1. Extreme Tensile Strength
The multi-layer construction plus fibreglass reinforcement gives it exceptional tear and stress resistance.
2. Permanent Fibre-Bond Seal
Once the adhesive activates, it merges with the box fibres and forms a tamper-evident lock.
3. Performs Under Harsh Conditions
Composite tape holds strong in:
- humidity
- extreme temperatures
- vibration-heavy freight
- cold storage environments
4. Excellent for Export Packaging
Long-distance shipments need seals that will not fail mid-transit. Composite tape guarantees that reliability.

5. Eco-Friendly + Industrial Strength
Even with composite reinforcement, this tape is still more sustainable than PP or PVC plastic tapes.
How Water Activated Composite Tape Is Made
Composite WAT is engineered using a layered design:
- Outer Kraft Layers: Provides structure and printable surface
- Starch Adhesive Layer: Activates with water to penetrate carton fibres
- Reinforcement Mesh: Fibreglass or synthetic threads improve tear resistance
- Bonding Layers: Additional adhesive layers enhance firmness and durability
This construction makes composite WAT the strongest type of gummed tape available commercially.
Best Uses for Water Activated Composite Tape
Composite reinforced tape is perfect for:
- heavy industrial machinery
- metal components and auto parts
- electronics and high-value shipments
- cross-border shipping
- agricultural exports
- multi-layer corrugated cartons
- stacked pallet shipments
- fragile product packaging

How to Use Water Activated Composite Tape (Step-by-Step)
Step 1: Use a Water Activated Tape Dispenser
Automatic or manual dispensers apply moisture evenly and cut accurate lengths.
Equipment available here:

Step 2: Ensure Proper Moisture Activation
Composite tape requires full adhesive activation for maximum bond strength.
Step 3: Apply Firmly on the Carton Seam
Because composite tape is extremely strong, a single strip typically seals even large cartons.
Step 4: Use H-Seal Method for Extra Protection
Applied on heavy cartons to reinforce edges and prevent bursting.
Step 5: Let the Bond Set
Composite WAT sets quickly, but the bond grows stronger as it dries.
Water Activated Composite Tape vs Reinforced WAT vs Plastic Tape
Composite WAT vs Reinforced WAT
| Feature | Composite WAT | Reinforced WAT |
|---|---|---|
| Strength | Maximum | High |
| Weight Capacity | 20–40 kg | 10–20 kg |
| Fiber Bond | Strongest | Strong |
| Durability | Extreme | Moderate-High |
| Best For | Industrial, export, heavy loads | Everyday shipping |
Composite WAT vs Plastic Tape
| Feature | Composite Tape | Plastic Tape |
|---|---|---|
| Adhesion | Permanent | Peelable |
| Durability | Very high | Low |
| Eco-friendly | Yes | No |
| Material waste | Low | High |
| Aesthetic | Clean | Messy |
| Security | Tamper-evident | Not secure |
If security, strength, and sustainability matter composite WAT wins without competition.
Why Brands Are Switching to Water Activated Composite Tape
Here’s what businesses say after switching:
- fewer carton failures
- fewer returns and damage claims
- cleaner presentation
- reduced tape usage
- faster sealing lines
- significant labour savings
- better sustainability outcomes
When packaging matters, composite WAT gives your brand a professional, trustworthy edge.
When You Should Absolutely Use Composite Tape
Choose composite tape if you pack:
- fragile products
- oversize cartons
- export-bound shipments
- thick corrugated boxes
- temperature-sensitive goods
