Water activated tape reinforced has become the industry’s top choice for sealing heavy-duty, high-value and export cartons. If you’re dealing with packaging that fails under pressure, boxes that split in transit, or plastic tape that never seems to hold, reinforced water activated tape (RWAT) is the upgrade that transforms your entire packaging workflow.
This guide breaks down everything you need to know from construction and benefits to correct application and best use cases. If you ship products that demand absolute security, reinforced WAT is exactly what you need.
What Is Water Activated Tape Reinforced?
Reinforced water activated tape is a kraft paper gummed tape embedded with fibreglass cross-weave threads that dramatically increase tensile strength. Once moistened, its starch-based adhesive merges with carton fibres, creating a permanent, fibre-deep seal that’s stronger than plastic packing tape.
It is used by high-volume eCommerce companies, industrial manufacturers, pharmaceuticals, food exporters and 3PL facilities for cartons that must stay sealed no matter what.

Why Water Activated Tape Reinforced Is So Popular
Businesses are shifting to water activated tape reinforced because it solves the biggest problems in packaging:
1. Unmatched Strength
The fibreglass reinforcement gives the tape extreme tear resistance, ideal for:
- overfilled cartons
- stacked pallet shipments
- long-haul freight
- industrial loads
2. Permanent, Tamper-Evident Seal
Any attempt to open the box visibly damages the surface a critical security feature.
3. Perfect for Heavy Cartons
Reinforced WAT prevents bursting seams, even when cartons are under pressure or movement.

4. Eco-Friendly Material
Even with fibreglass strands, reinforced WAT is more sustainable than plastic tapes.
5. Professional Presentation
A single strip seals the box neatly and cleanly no messy overlaps, no peeling edges.
How Water Activated Tape Reinforced Is Constructed
Reinforced WAT is engineered using:
- Natural kraft paper
- Water-activated starch adhesive
- Fibreglass threads (usually in diamond or cross-weave patterns)
- Eco-safe bonding layers
This layered design creates both high tensile strength and permanent adhesion.
When to Use Water Activated Tape Reinforced
Reinforced water activated tape is ideal for:
- Heavy or oversized cartons
- Multi-layer corrugated boxes
- Export shipments
- Fragile goods requiring secure sealing
- Stacking and palletised freight
- ECommerce products with high value
- Cold storage shipments
If the carton weight exceeds 10–15 kg, reinforced WAT becomes the superior choice.
Step-by-Step: How to Use Reinforced Water Activated Tape
Step 1: Use a Water Activated Tape Dispenser
Manual or electric WAT dispensers moisten the adhesive and cut tape lengths accurately.

Step 2: Properly Moisten the Adhesive
The adhesive activates when wet. Without proper moisture, the tape won’t bond effectively.
Step 3: Apply One Strip Down the Centre Seam
Because reinforced tape is strong, one strip is often enough even on large cartons.
Step 4: Use an “H-Seal” for Heavy Loads
Add two extra side strips to prevent opening under pressure.
Step 5: Let It Set for a Few Seconds
The adhesive penetrates and bonds instantly, but strength continues to increase as it dries.
Water Activated Tape Reinforced vs Standard Kraft WAT
| Feature | Reinforced WAT | Non-Reinforced WAT |
|---|---|---|
| Strength | Maximum | Moderate |
| Weight Capacity | Heavy shipments | Standard parcels |
| Tamper Evidence | High | High |
| Cost | Slightly higher | Lower |
| Best Use | Industrial, export, stacked freight | eCommerce, general packing |
If you’re shipping light to medium-weight goods, standard WAT works beautifully.
For anything above 10 kg, choose reinforced.
Water Activated Tape Reinforced vs Plastic Tape
Plastic tape simply can’t match RWAT in strength or sustainability.
| Category | Reinforced WAT | Plastic Tape |
|---|---|---|
| Bond Strength | Permanent | Weak under pressure |
| Material | Kraft paper + glass fibers | PVC or PP plastic |
| Sustainability | High | Low |
| Climate Resistance | Strong | Sensitive |
| Tape Usage | One strip | Multiple strips |
| Security | Tamper-evident | Can be peeled off |
If you’re tired of boxes reopening during transport, reinforced WAT is the fix.
