When it comes to sealing packages securely, especially for shipping or long-term storage, gummed tape is one of the most reliable options. Also known as water-activated tape (WAT), gummed tape is made with a natural adhesive that bonds strongly to cardboard when moistened. Unlike pressure-sensitive tapes, it forms a permanent seal that deters tampering and strengthens the package.
But what’s the best way to apply it? That depends on your volume, your packaging workflow, and your budget. Below, we explore the most common methods of applying gummed tape—ranging from manual to high-speed automated solutions.
1. Manual Application with a Sponge or Brush
Best for: Low-volume packaging, small businesses, or occasional use.
The simplest method involves using a damp sponge or brush to activate the adhesive on the tape. Just wet the gummed side evenly and press the tape onto the box, smoothing it down by hand.
Pros:
-
Low-cost
-
No special equipment required
Cons:
-
Time-consuming
-
Less consistent application
-
Can get messy
2. Handheld Gummed Tape Dispensers
Best for: Small to medium packaging operations.
Handheld gummed tape dispensers have a built-in water reservoir and wetting brush. You feed the tape through the dispenser, which moistens it automatically before application. These tools make it easier and faster to apply gummed tape than using a sponge.
Pros:
-
Faster than manual sponging
-
More consistent wetting
-
Portable
Cons:
-
Limited to moderate usage
-
Still slower than electric options
3. Manual (Non-Electric) Gummed Tape Dispensers
Best for: Moderate-volume packaging stations.
These tabletop dispensers let you pull the tape manually and use a lever or handle to cut the desired length. They typically include a built-in water tray and brush to wet the tape as it’s dispensed.
Pros:
-
Durable and easy to use
-
Ideal for consistent tape length
-
Affordable for growing operations
Cons:
-
Manual effort required
-
Slower than electric models
4. Electric Gummed Tape Dispensers
Best for: High-volume packaging environments like warehouses and fulfillment centers.
Electric dispensers automatically moisten, cut, and dispense the tape to a preset length with the push of a button. Some advanced models even integrate with automation systems or use sensors to adjust tape length on the fly.
Pros:
-
Fast and efficient
-
Very consistent application
-
Ideal for repetitive packing tasks
Cons:
-
Higher upfront cost
-
Requires power and maintenance
5. Automated Case Sealers with Gummed Tape Integration
Best for: Large-scale industrial packaging lines.
For maximum efficiency, some businesses integrate gummed tape into fully automated case sealing machines. These machines fold the box flaps and apply the tape to both the top and bottom of the carton, without any human intervention.
Pros:
-
High-speed application
-
Eliminates manual labor
-
Perfect for high-demand operations
Cons:
-
Significant investment
-
Requires setup and space
Final Thoughts
Choosing the right method to apply gummed tape depends on how much packaging you do and what your workflow looks like. For occasional users, a sponge or handheld dispenser may be enough. But if you handle dozens or hundreds of boxes a day, investing in a manual or electric dispenser, or even automation, can save time, increase consistency, and reduce waste.
Regardless of how you apply it, gummed tape offers a professional, tamper-evident seal that adds strength and security to your packages. It’s a smart upgrade for businesses that care about protection and presentation.
