Water-activated tapes (WATs), also known as gummed tapes, are becoming increasingly popular in the packaging industry due to their strong adhesion and eco-friendly properties. This guide will walk you through the benefits, application techniques, and best practices for using WATs effectively if you’re new to them.
Benefits of Water-Activated Tapes
- Durability and Strength
Water-Activated Tapes are known for their durability and strength. Once the adhesive is activated by water, it forms a strong bond with the packaging material, which is particularly useful for heavy-duty or long-distance shipments. This bond is tamper-evident, meaning any attempt to open the package will be noticeable.
- Eco-Friendly Properties
WATs are made from kraft paper and a starch-based adhesive, both of which are biodegradable and compostable. This makes them a more environmentally friendly option compared to traditional plastic tapes. By using WATs, you can reduce your carbon footprint and contribute to more sustainable packaging practices.
- Secure Adhesion
The adhesive used in WATs penetrates the fibres of the cardboard, creating a bond that is significantly stronger than that of pressure-sensitive tapes. This secure adhesion ensures that packages remain sealed during transit, reducing the risk of tampering and improving overall package security.
Preparation Before Application
- Surface Cleanliness
Before applying WAT, ensure that the surface of the package is clean and dry. Dust, dirt, or moisture can interfere with the adhesive’s effectiveness, so it’s crucial to wipe down the surface with a clean cloth before beginning the taping process.
- Activating the Adhesive
To activate the adhesive on WATs, you’ll need to apply water evenly across the tape. This can be done using a sponge, brush, or a water-activated tape dispenser. Make sure the adhesive is fully moistened but not oversaturated, as too much water can weaken the bond.
Proper Application Techniques
- Correct Water-to-Tape Ratio
Achieving the right water-to-tape ratio is key to ensuring strong adhesion. Too little water can prevent the adhesive from activating properly, while too much water can make the tape difficult to handle and weaken the bond. Practice with a few test pieces to find the optimal amount of water for your specific tape and application method.
- Applying Even Pressure
After applying the tape, use a squeegee or a roller to apply even pressure across the surface. This helps to eliminate air bubbles and ensures that the tape adheres firmly to the package. Make sure to press down firmly on the edges to prevent them from lifting.
- Sealing the Edges Securely
Pay special attention to sealing the edges of the package. Run your finger or a tool along the edges to ensure the tape is securely attached. This helps to prevent the tape from peeling back and ensures a tamper-evident seal.
Curing and Drying Process
- Allowing Sufficient Time for the Tape to Set
After applying the tape, it’s important to allow sufficient time for the adhesive to set. This usually takes a few minutes, but it can vary depending on the humidity and temperature of your environment. Avoid moving or handling the package until the adhesive is fully set.
- Avoiding Premature Handling
Handling the package before the adhesive has fully set can cause the tape to peel or lose its adhesion. Ensure that the tape is completely dry and firmly bonded before moving the package to avoid any issues.
Tips for Storage and Maintenance
- Choosing the Right Water-Activated Tape
Different types of WATs are designed for different applications. Consider factors such as the weight of your packages, the shipping distance, and environmental conditions when choosing the right tape. For high-quality options, check out the selection at Packmile.
- Proper Storage
Store your WAT rolls in a cool, dry place to prevent the adhesive from drying out or becoming too sticky. Avoid exposing the rolls to direct sunlight or extreme temperatures, as this can affect the tape’s performance.

FREQUENTLY ASKED QUESTIONS
Why is my water-activated tape not sticking?
If your water-activated tape is not sticking, it could be due to insufficient moisture, a dirty surface, or improper storage. Make sure to evenly moisten the adhesive, clean the application surface, and store the tape in a cool, dry place.
Is water-activated tape worth it?
Yes, water-activated tape is worth it for its strong adhesion, eco-friendly properties, and tamper-evident seal. It provides a secure and sustainable packaging solution, especially for heavy-duty shipments.
How long does water-activated tape take to dry?
Depending on the environmental conditions, it typically takes a few minutes to set and dry. It’s best to wait until the tape is fully dry before handling the package.
Is water-activated tape better than regular tape?
Water-activated tape offers several advantages over regular tape, including stronger adhesion, tamper-evident seals, and eco-friendly materials. It is especially beneficial for secure and sustainable packaging needs.
