Gummed tape, also known as water-activated tape, is a highly effective and reliable sealing solution used widely in packaging, shipping, and even framing artwork. Unlike regular adhesive tapes, gummed tape has a water-activated adhesive that forms a strong, tamper-evident bond with cardboard and paper surfaces. This makes it particularly popular in commercial settings, especially with businesses that require secure, professional-looking packaging. While it may seem slightly more complicated to use than regular tape, understanding how to use gummed tape properly can lead to better results and improved efficiency in sealing boxes and materials.
What Is Gummed Tape?
Understanding Its Composition
Gummed tape is made from a paper backing typically kraft paper coated with a starch-based adhesive that activates when moistened. It is often reinforced with fiberglass threads for added strength, making it durable and resistant to tearing. Once applied and dried, gummed tape forms a permanent bond that’s difficult to peel off without damaging the box.
Different Types of Gummed Tape
- Non-reinforced gummed tape: Suitable for lightweight packages and smooth surfaces. It offers a clean and eco-friendly seal.
- Reinforced gummed tape: Contains fiberglass filaments for added strength. Ideal for heavy boxes or international shipping.
Why Choose Gummed Tape Over Other Tapes?
Many individuals and businesses choose gummed tape for several practical reasons:
- Strong bond: The adhesive penetrates the surface of cardboard, making it more secure than pressure-sensitive tapes.
- Tamper-evident: Any attempt to remove the tape results in visible damage to the box, ensuring product integrity during shipping.
- Eco-friendly: Most gummed tapes are biodegradable and recyclable, unlike plastic-based alternatives.
- Professional appearance: Creates a clean, seamless seal that enhances the presentation of packages.
Tools Needed to Use Gummed Tape
Using gummed tape requires a few simple tools to make the process smooth and effective:
- Water source: A sponge or brush soaked in clean water to activate the adhesive.
- Dispenser: A gummed tape dispenser can wet, measure, and cut the tape automatically for high-volume use.
- Scissors or cutter: If applying manually, you’ll need a sharp blade or scissors to trim the tape.
How to Use Gummed Tape: Step-by-Step Guide
Step 1: Prepare the Surface
Ensure the surface of the box or material you’re taping is clean and dry. Remove dust, oils, or any loose ptopics that may interfere with adhesion. The more even the surface, the better the tape will bond.
Step 2: Measure and Cut the Tape
If you’re not using a dispenser, measure the length of tape needed to cover the seam or flap. Cut the tape to size using scissors or a utility knife. Be sure to leave at least an inch overhang on either side to secure the edges properly.
Step 3: Activate the Adhesive
Use a sponge, damp cloth, or brush to apply water to the adhesive side of the gummed tape. Do not oversaturate it too much water can cause the tape to wrinkle or weaken. The tape should be evenly moist, not dripping.
Step 4: Apply the Tape
Place the moistened side of the tape onto the seam or surface you’re sealing. Press down firmly along the entire length, using your hand or a rubber roller to smooth it out and ensure full contact. Pay extra attention to corners and edges.
Step 5: Allow to Dry
Let the tape dry completely before handling or stacking the sealed boxes. This ensures the adhesive sets properly and achieves maximum strength. Drying time usually takes a few minutes depending on humidity and temperature.
Tips for Better Results
Work on a Flat Surface
To avoid wrinkles or uneven seals, always apply gummed tape on a flat surface. Use a table or packing station for better control and accuracy during the process.
Don’t Overwet the Tape
Too much water can reduce the effectiveness of the adhesive and may cause the paper to tear or buckle. Light, even moisture is enough to activate the glue.
Use Reinforced Tape for Heavy Packages
If you’re sealing boxes that will hold heavy or valuable items, reinforced gummed tape is a better choice. The fiberglass strands provide added strength and durability during transport.
Use a Gummed Tape Dispenser for High Volume
For businesses that seal a lot of packages daily, investing in a water-activated tape dispenser is a smart move. These machines automate the wetting and cutting process, increasing speed and consistency.
Applications of Gummed Tape
Shipping and Packaging
Gummed tape is commonly used in e-commerce and shipping warehouses for sealing corrugated boxes. Its strong bond ensures packages remain closed and secure during transit, even under rough handling.
Artwork and Framing
Artists and framers use gummed paper tape for hinging artwork to mats and backing boards. Since the tape is acid-free and archival, it doesn’t damage delicate paper over time.
Bookbinding
Gummed linen tape or paper tape is also used in traditional bookbinding for creating strong, long-lasting spines and covers. Its ability to create permanent bonds is highly valued in the craft.
Crafts and DIY Projects
For crafters, gummed tape can be a versatile material in making journals, collage art, and handmade packaging. Its ease of use and eco-friendliness make it a great choice for sustainable crafting.
Common Mistakes to Avoid
- Not moistening the tape evenly: This can result in weak spots where the tape does not stick properly.
- Applying to wet or oily surfaces: The adhesive needs a clean surface to bond effectively.
- Handling too soon after application: Always let the tape dry before moving or stacking boxes.
- Using on plastic or non-porous surfaces: Gummed tape works best on paper and cardboard. It may not adhere well to slick materials.
Maintaining Your Tape and Tools
Store your gummed tape in a cool, dry place to prevent premature activation of the adhesive. Avoid exposure to high humidity or direct sunlight, as this can weaken the glue. Clean your sponge or dispenser regularly to avoid buildup or mold. Keeping your tools in good condition ensures smooth operation and a longer lifespan for your materials.
Knowing how to use gummed tape effectively is a valuable skill for anyone involved in shipping, packaging, crafting, or art presentation. With its strong adhesive, tamper-evident properties, and eco-friendly design, it offers a superior alternative to plastic tapes. By following the correct steps moistening properly, applying with care, and allowing time to dry you can create professional, secure seals every time. Whether you’re running a business or simply organizing your home workspace, gummed tape can elevate the quality and reliability of your packaging efforts.
