Water-activated kraft tape is gaining popularity in the packaging industry as a sustainable and efficient sealing solution. This innovative adhesive tape offers numerous benefits, including durability, eco-friendliness, and tamper-evident properties, making it a top choice for businesses worldwide. Whether you’re in e-commerce, manufacturing, or logistics, water-activated kraft tape can revolutionize your packaging process.
What is Water Activated Kraft Tape?
Water activated kraft tape, often referred to as WAT or gummed tape, is a kraft paper-based adhesive tape that bonds securely to surfaces upon activation with water. Unlike traditional plastic tapes, this tape is made from natural kraft paper and reinforced with fiberglass or synthetic fibers for added strength.
Its adhesive layer, typically starch-based, forms a permanent bond with packaging materials like corrugated boxes, providing an unbreakable seal.

How Water Activated Kraft Tape Works
The activation process of WAT is simple yet effective. Once water is applied to the adhesive side, the starch-based glue becomes tacky, allowing it to penetrate and bond with the carton fibers. This creates a seal that is not only strong but also tamper-evident, as any attempt to open the package will leave visible damage.
Features of Water Activated Kraft Tape
Strength and Durability
Water-activated kraft tape can withstand extreme conditions, including heavy loads and fluctuating temperatures. Its reinforced fibers provide additional tensile strength, ensuring your packages remain secure during transit.
Eco-Friendliness
Made from biodegradable kraft paper and natural adhesives, this tape is a sustainable alternative to plastic tapes, aligning with eco-conscious business practices.
Tamper-Evident
Unlike other tapes, WAT leaves noticeable marks if tampered with, adding an extra layer of security to your shipments.
Customizable
Businesses can print logos, branding, or instructions on WAT, enhancing brand visibility and professionalism.
Applications in Various Industries
Water-activated kraft tape has versatile applications across multiple sectors:
- E-commerce: Securing online orders with tamper-evident seals.
- Food Packaging: Ensuring a hygienic and eco-friendly packaging solution.
- Logistics: Protecting goods during transportation.
- Manufacturing: Bundling and sealing industrial products.
Benefits of Water Activated Kraft Tape
- Cost Efficiency: A single strip often suffices, reducing material usage.
- Sustainability: Completely recyclable, it helps reduce plastic waste.
- Enhanced Branding: Custom designs make packaging visually appealing and professional.
Comparing Water Activated Kraft Tape to Other Tapes
| Property | WAT | Acrylic Tape | Hot-Melt Tape |
|---|---|---|---|
| Material | Kraft paper | Plastic | Plastic |
| Adhesion | Water-activated starch adhesive | Pressure-sensitive adhesive | Hot-melt adhesive |
| Environmental Impact | Biodegradable | Non-biodegradable | Non-biodegradable |
| Security | Tamper-evident | Low | Moderate |
Environmental Benefits
Water-activated kraft tape significantly reduces the environmental impact of packaging by eliminating the need for non-recyclable materials. It contributes to a circular economy, as it decomposes naturally without harming ecosystems.
Tips for Using Water Activated Kraft Tape
- Activate Properly: Use a water dispenser or sponge for even activation.
- Apply Pressure: Ensure proper adhesion by pressing firmly after application.
- Store Correctly: Keep in a cool, dry place to maintain adhesive integrity.
Common Misconceptions About Water Activated Kraft Tape
- It’s Weak: Reinforced WAT is as strong as, if not stronger than, plastic tapes.
- It’s Expensive: Its long-term cost efficiency outweighs its initial cost.
