What is the difference between water-activated tape and kraft paper tape?   Both water-activated tape and kraft paper tape are used for sealing cartons, especially in packaging applications that emphasize environmental sustainability or brand promotion. While they may appear similar at first glance, their functions differ slightly, and they are made from different materials. Understanding these differences can help ensure you select the right tape for your packaging needs.   Although both are paper-based and eco-friendly, the key differences lie in the type of adhesive and the application method.   What is Water-Activated Tape?   Water-activated tape, commonly referred to as gummed tape, is a carton-sealing tape that requires water to activate its adhesive. It is primarily made from kraft paper and coated on one side with a starch-based adhesive. Once moistened, the adhesive bonds firmly to the carton surface, creating a tamper-evident seal.   This tape is widely used for sealing lightweight to medium-weight cartons, particularly for export or long-distance transportation, as the adhesive penetrates the carton surface, forming a strong and durable seal.reinforce water-activated tapes also incorporate fiberglass yarn or Plant fiber yarn, enhancing tensile strength and security.   Reinforced water-activated tape contains embedded fiberglass yarns or Plant fiber yarn, which improve its durability and tear resistance. It is a reliable choice for heavy or high-value packaging that requires additional strength.    It has a clean and simple appearance, making it suitable for standard carton sealing. While it provides strong adhesion, it is typically better suited for lighter-weight cartons.   Water-activated tape requires a tape dispenser equipped with a water reservoir to moisten the adhesive. These dispensers ensure consistent activation of the adhesive, allowing users to seal cartons quickly and efficiently. For higher efficiency, electric water-activated tape dispensers can be used. The standard widths for water-activated tape are 70 mm and 72 mm. JL3 offers custom width options based on specific application requirements.   What is Kraft Paper Tape?   Kraft paper tape is a pressure-sensitive tape made from kraft paper. Unlike water-activated tape, it does not require water to adhere and can be applied manually or with a tape dispenser from JL3. It provides a simple and sustainable solution for sealing lightweight to medium-weight cartons.   For businesses seeking an eco-friendly tape that can also be printed with brand logos, kraft paper tape is an ideal choice. It blends seamlessly with brown cartons, has a writable surface, and is convenient for labeling or imprinting.   Kraft paper tape mainly comes in two types: hot-melt adhesive and water-sensitive adhesive. The hot-melt type offers strong adhesion and excellent initial tack, while the water-sensitive type provides superior resist...

Filament tape and strapping tape are commonly used for bundling and securing items during transportation. While these tapes serve similar purposes, there are notable differences in their construction and applications. Understanding these differences ensures you choose the right tape for your specific needs.   What is Filament Tape? Filament tape is designed for heavy-duty applications, offering high tensile strength due to its fiberglass reinforcement. The filaments woven into the tape’s structure make it highly durable, tear-resistant, and capable of withstanding significant pressure during transit. It is ideal for sealing cartons containing heavy and fragile items that need extra support.   There are two types of filament tape available: One-Way Filament Tape and Two-Way Filament Tape. These variations offer different reinforcement patterns for diverse applications.   One-Way Filament Tape: One-Way Filament Tape has fiberglass reinforcement in one direction. It is often referred to as "single-woven" filament tape. This version is typically more cost-effective but may be prone to splitting along the length of the tape due to the absence of crosswise reinforcement.   Two-Way Filament Tape: Two-Way Filament Tape, or "cross-weaved" filament tape, features reinforcement in both directions. This construction enhances its strength, preventing splitting along either axis. While it is more expensive than one-way tape, it is suitable for more demanding applications where durability is critical.   Application: Filament tape requires a tape dispenser for efficient application, as it cannot be torn by hand due to its strong, fibrous structure. Dispensers are designed to easily cut the tape once applied, making the process faster and more ergonomic.   Sizing Options: Filament tape is available in a range of widths, from 12mm to 96mm, and can be custom-slit to meet specific application requirements.   What is Strapping Tape? Strapping tape is a highly tensile adhesive tape used for bundling and securing items together, often as a temporary alternative to traditional strapping materials like polypropylene. This tape is perfect for applications where an easy-to-remove and non-residue adhesive is needed. It is commonly used for securing pallet loads before they are stretch-wrapped or for bundling products during transit.   Strapping tape is known for its low stack and clean removal, meaning it won’t leave adhesive residue behind on the surface of the secured items. It’s also a go-to for applications where quick, cost-effective bundling solutions are required.   Application: Strapping tape is typically applied with a strapping tape dispenser to ensure consistent tension and secure bundling. These dispensers are robust and easy to use, making the process fast and convenient.   Sizing and Color Options: Strapping tape is available in two standard colors—clear and White. Width options typicall...

Water-activated tape (WAT), also known as gummed tape, kraft paper tape, or brown paper tape, provides a stronger and more secure seal for cartons, while also streamlining your packaging process. Once you decide to use WAT, the next step is to choose the appropriate type of dispenser.   Should You Choose a Manual or Electric Water-Activated Tape Dispenser?   The first decision when selecting a WAT dispenser is whether to go with a manual or an electric model.

Water-Activated Tape (WAT), also known as gummed tape, is a durable and effective carton sealing solution made from kraft paper and a starch-based adhesive. Unlike traditional pressure-sensitive tapes, WAT becomes adhesive when activated by water, allowing it to form a secure bond with the surface of corrugated cardboard. This article explores how water-activated tape works and its significance in the context of transportation, packaging, and environmental sustainability. How Water-Activated Tape Works and Its Environmental Benefits Water-activated tape is manufactured with a natural starch-based adhesive that remains dormant until it is moistened. Once activated by water, the adhesive forms a strong bond with the fibers of corrugated cardboard. This bond is so secure that the tape essentially fuses with the carton, creating a tamper-evident seal. Furthermore, since the tape is made of paper and starch, it is recyclable, biodegradable, and even compostable—making it an environmentally responsible choice. The application process includes: Activation: The starch adhesive on WAT is dry and inactive when on the roll. To activate it, the tape must pass through a water-activated tape dispenser, which applies an even layer of water to trigger its adhesive properties. Application: Once moistened, the tape is applied to the surface of the box. The adhesive interacts directly with the cardboard fibers, allowing for a rapid and much stronger seal compared to most pressure-sensitive tapes. Bonding: The moist adhesive penetrates the fibers of the carton material. As it dries, the bond becomes permanent, making the tape extremely difficult to remove without visibly damaging the package. Tamper Evidence: One of the key advantages of WAT is its enhanced security. Any attempt to open the package will result in noticeable damage to the carton, making tampering immediately evident. Why Water-Activated Tape Is an Ideal Packaging Solution Water-activated tape is particularly favored in the e-commerce, logistics, and shipping industries for several compelling reasons: Strength and Durability: WAT provides a robust seal that withstands the rigors of transportation, rough handling, and varying environmental conditions. Its strength makes it a preferred solution for both light- and medium-duty packaging. Tamper Resistance: Because the tape forms a permanent bond with the carton, any unauthorized opening attempt will leave clear signs of tampering—adding a valuable layer of security during transit. Cost Efficiency: While the initial cost of WAT may be slightly higher than pressure-sensitive tape, its ability to seal cartons with a single strip can reduce material use and long-term packaging costs. Sustainability: All water-activated tapes are made from renewable materials and can be easily recycled along with cardboard boxes. For businesses aiming to reduce their environmental impact, WAT offers a sustainable packaging alternative. Conclusion Water-activated t...
