When it comes to sealing packages, there are countless options available, including staples, glue, and a variety of different tapes. However, one type of tape stands out for its exceptional performance, unique bonding abilities, and the added security it provides—water-activated kraft tape. While it offers unparalleled sealing power, it also comes with its own set of challenges. In this article, we will dive deep into the pros and cons of water-activated kraft tape, exploring its unique features, potential drawbacks, and considerations that might influence your decision to switch from traditional sealing methods.
What Is Water-Activated Kraft Tape?
Water-activated kraft tape, often referred to as gummed tape, is a paper-based tape that uses water to activate its adhesive. Unlike pressure-sensitive tapes that bond with pressure alone, water-activated tape requires the application of water to activate the adhesive, allowing it to form a strong bond with the surface it is applied to. This tape is commonly used in heavy-duty packaging and offers a level of security and durability not typically seen in other sealing options.
Made primarily from kraft paper and an adhesive activated by water, this tape offers a unique bonding process. When applied to a package, the adhesive bonds so securely with the cardboard that removing the tape results in damage to the box itself, creating a tamper-evident seal. It is commonly used in situations where security and the protection of contents are paramount, such as shipping high-value goods or sealing packages in industries like e-commerce and pharmaceuticals.
1. Pros of Water-Activated Kraft Tape
Water-activated kraft tape is known for its numerous benefits, making it an ideal choice for packaging operations in various industries. Here are some of the standout advantages of this tape:
1.1 Exceptional Bonding Strength
One of the most significant advantages of water-activated kraft tape is its ability to form an incredibly strong bond. Once the tape is moistened and applied, the adhesive activates, bonding tightly to the surface of the cardboard. This bond is so strong that when the tape is removed, it often causes damage to the packaging material, leaving behind permanent evidence of tampering. This tamper-evident feature makes water-activated tape a preferred option for securing valuable goods and sensitive packages that require protection from unauthorized access.
1.2 Increased Durability
Water-activated tape is known for its durability. The paper used in the tape, combined with the water-activated adhesive, makes it resilient and capable of withstanding tough handling, including exposure to high and low temperatures. Many other types of tapes, such as pressure-sensitive tapes, fail under extreme conditions, but water-activated tape can endure such stress. This makes it an excellent choice for packaging that will be transported in varying environments or subjected to heavy handling.
1.3 Tamper-Evident Seal
Another major advantage of water-activated kraft tape is that it creates a tamper-evident seal. Once the tape is applied and dried, it bonds so securely that attempting to remove it will leave visible marks or damage on the packaging. This feature provides a high level of security and is crucial in preventing theft or tampering during transit. If a package is opened or the tape is removed, the integrity of the box is compromised, providing clear evidence that the package has been tampered with. This makes it ideal for industries where security is critical, such as e-commerce, pharmaceuticals, and electronics.
1.4 Eco-Friendly Option
Water-activated kraft tape is made primarily from paper, which is a renewable resource. The adhesive used is water-based, making it a more eco-friendly option compared to other types of tape, particularly those made with petroleum-based adhesives. Additionally, since it is paper-based, it is fully recyclable, which makes it an attractive choice for businesses focused on sustainability. If your company is looking for ways to reduce its carbon footprint or adhere to environmentally conscious practices, water-activated tape is an excellent choice.
1.5 Custom Branding Opportunities
Water-activated kraft tape can be fully customized with logos, messages, or designs. This makes it an ideal option for businesses looking to brand their packaging and leave a lasting impression on customers. The smooth surface of the tape allows for high-quality printing, enabling you to incorporate your brand identity directly into your packaging. This customization enhances the unboxing experience for customers and offers additional marketing opportunities while maintaining the tape’s functional benefits.
2. Cons of Water-Activated Kraft Tape
While water-activated kraft tape offers several significant advantages, there are also some potential drawbacks to consider before making the switch. Here are some of the disadvantages of this tape:
2.1 Higher Initial Investment
One of the most significant downsides to using water-activated kraft tape is the initial investment required to switch from traditional tape methods. Water-activated tape requires a specialized dispenser that applies water to the tape as it is dispensed, ensuring the adhesive is activated. While the tape itself is not drastically more expensive than other types of tape, the dispensers can be costly. Electric dispensers, which automate the process and increase efficiency, are especially expensive, and while they are durable and long-lasting, the upfront cost might not be feasible for smaller businesses or those with lower packaging volume.
2.2 Requires Proper Storage and Maintenance
Water-activated tape is sensitive to moisture, which means proper storage is crucial. The tape should be stored in a dry, cool place to avoid premature activation of the adhesive due to humidity or water exposure. Additionally, the dispensers need regular maintenance. If the brush or sponge that applies water to the tape is not cleaned and maintained properly, it could lead to an uneven application of moisture, resulting in poor adhesion. Regular cleaning and care are essential to keep the dispenser working efficiently and avoid waste.
2.3 Slower Application Process
Using water-activated tape can be slower than using other types of tape, especially in high-volume packaging operations. While dispensers can speed up the process, the need to apply water to the tape adds an extra step compared to pressure-sensitive tapes, which bond immediately with pressure. This additional step might slow down packaging operations, particularly if there is a high demand for rapid packing or if you are working in a fast-paced warehouse environment.
2.4 Requires Specialized Training
Since water-activated tape requires special dispensers and handling techniques, employees may need to be trained on how to use the equipment correctly. This could add to the time and costs involved in the transition. Proper training is essential to avoid issues such as improper adhesive activation, uneven application, or poor bonding, which can all lead to packaging failure and damage. Businesses must factor in training time and costs when considering whether to adopt water-activated tape for their packaging needs.
3. Two Additional Features of Water-Activated Kraft Tape
In addition to its primary features, water-activated kraft tape also offers some additional benefits that can make it even more appealing for certain applications:
3.1 Increased Packaging Integrity
Water-activated tape helps to improve the overall integrity of packaging. The strong bond it creates not only secures the contents of the box but also helps reinforce the structure of the packaging itself. This added strength makes it less likely that packages will get damaged during transit, reducing the likelihood of returns due to damaged products. The tape itself is sturdy enough to support the weight of heavy items, making it a reliable choice for shipping bulky goods that require extra reinforcement.
3.2 Reduced Packaging Waste
Although water-activated tape requires a larger initial investment, it can help reduce material waste in the long run. Since it requires less tape to achieve a stronger bond, businesses can use less material per package. This can be especially beneficial for high-volume shippers, as it leads to a reduction in both tape usage and shipping costs. Additionally, since water-activated tape creates a secure seal that does not fail, businesses will spend less on redoing packaging or dealing with damaged shipments.
