Gummed paper tape, often technically referred to as water-activated tape in our product specifications, represents a distinct category of carton sealing solutions designed for high-security and heavy-duty packaging applications. Unlike pressure-sensitive tapes that rely on synthetic tackifiers to adhere to the surface of a box, gummed paper tape utilizes a starch-based adhesive system that, upon wetting, penetrates the corrugated fibers of the carton to create a permanent, destructive bond. This fundamental difference means that once the tape is applied and dried, it effectively becomes part of the box itself, making it nearly impossible to remove without leaving visible evidence of tampering, a critical feature for industries transporting valuable electronics or sensitive goods.   The structural composition of gummed paper tape varies significantly to meet different load-bearing requirements. For general light-duty sealing, a non-reinforced kraft paper backing, such as our JLN-370 model, provides a clean and recyclable seal suitable for lighter boxes. However, industrial applications typically demand higher tensile strength, which is why we engineer reinforced versions like the JLN-3150 and KN-37120. These tapes sandwich a reinforcement layer between two sheets of kraft paper; the JLN-3150, for instance, utilizes fiberglass strands in a specific pattern to resist splitting and tearing during transit. For heavier loads, the KN-37120 increases the density of this fiberglass network and the weight of the paper backing to handle significant mechanical stress during logistics handling.   Sustainability is a driving force in the evolution of gummed paper tape, particularly as companies seek to eliminate plastic from their supply chains. While standard reinforced tapes contain fiberglass, which is not biodegradable, we have introduced fully degradable alternatives like the JLN-3150E. This model replaces the traditional fiberglass reinforcement with plant-based yarn, maintaining the necessary tensile strength for light to medium-duty applications while ensuring that the entire tape—backing, adhesive, and reinforcement—is eco-friendly and recyclable. By selecting the appropriate grade of gummed paper tape, from the standard fiberglass-reinforced JLN-3150 to the heavy-duty KN-37120 or the eco-conscious JLN-3150E, packaging facilities can ensure load stability while aligning with environmental protocols.

When we discuss kraft paper adhesive tape in the context of professional packaging, we are usually looking at a balance between environmental considerations and actual sealing performance. Unlike standard plastic tapes, kraft paper options blend in with corrugated cardboard, creating a uniform look that many brands prefer, but the technical construction varies significantly depending on the adhesive system used. In our product line, we distinguish primarily between self-adhesive kraft tapes utilizing hot melt adhesives and water-activated tapes that rely on starch-based formulations.   For general applications where convenience is the priority, self-adhesive kraft paper tape is often the first choice for many manual packaging lines. Models like our JLN-2740H use a hot melt adhesive system that provides immediate tack without requiring water activation. This makes them similar in user experience to standard pressure-sensitive tapes but with a paper backing that creates a more sustainable package appearance. These tapes are designed for light-duty applications where the primary goal is a quick, clean closure without the need for an electric dispenser. We also offer reinforced versions in this category, such as the JLN-2953H or KN-28160E, which embed polyester or plant-based yarn to prevent the paper from snapping under tension, effectively bridging the gap between standard paper tape and stronger filament solutions.   However, for heavy-duty packaging and scenarios requiring tamper-evident security, water-activated tape remains the industrial standard. Our reinforced water-activated tapes, such as the JLN-3150 series, use a starch-based adhesive that penetrates the carton fibers once wet, creating a permanent bond that essentially welds the tape to the box. This is structurally different from pressure-sensitive adhesives that sit on top of the surface. To handle heavy items, we integrate fiberglass reinforcement in varying patterns; for instance, the JLN-3150 utilizes a fiberglass pattern with specific spacing to ensure the tape does not split during transit. This fiberglass network provides the structural integrity needed for shipping valuable goods like electronics or automotive parts, where a broken seal could mean lost inventory.   We also recognize that sustainability is driving changes in material composition, which is why we have developed degradable options within the kraft paper adhesive tape category. The JLN-3150E and KN-37120E models, for example, replace traditional fiberglass with plant-based yarn reinforcement while maintaining the robust starch-based adhesive system. This allows industrial users to maintain the bundling and sealing strength required for heavy-duty logistics without compromising on recyclability. Whether choosing the immediate tack of a hot-melt self-adhesive tape or the structural security of a water-activated starch adhesive, the selection process ultimately comes down to the specific weight of the g...

In the fast-paced world of modern logistics, finding the perfect balance between the premium aesthetic of tape and the operational speed of pressure-sensitive tape is essential. The image above captures the seamless and professional finish of the JLN-2750H, our premier Self-Adhesive Kraft Paper Tape. Unlike traditional Water Activated Tapes that require moisture to activate a starch adhesive, the JLN-2750H is engineered with a high-performance Hot Melt adhesive system. This distinct feature allows for instant application using standard handheld tape dispensers, eliminating the need for water reservoirs or electric machines. It is the ideal solution for warehouses that require the high-end look of paper tape but need the mobility and rapid sealing capabilities of a self-adhesive product. The JLN-2750H stands out not just for its convenience but for its reliable performance on corrugated surfaces. The tape features a robust Kraft paper backing  that blends naturally with cardboard cartons, creating a uniform and eco-friendly package appearance that plastic tapes simply cannot replicate. The Hot Melt adhesive provides an aggressive initial tack, ensuring an immediate and secure bond that holds firm during transit. For businesses committed to sustainability, this tape supports eco-conscious goals as its paper construction is more compatible with carton recycling streams than plastic alternatives.our JLN-2740H and JLN-2950H lines —to provide consistent unwinding and superior holding power. With the JLN-2750H, you achieve a tamper-evident, recyclable seal that enhances your brand image while streamlining your packing line efficiency.

Walking through a bustling warehouse, like the one captured in the photo above, you notice the rhythm of logistics. Boxes moving, forklifts humming, and the crucial final step: sealing the package. As someone who works deeply with these products at Fujian Jialong Adhesive Tape, I can tell you that the roll of tape sitting on that box isn't just a fastener; it is a security device. That is Reinforced Water Activated Tape, often called WAT or gummed tape, and it is rapidly replacing standard plastic tape for high-volume shippers. If you look closely at the roll in the image, you can see the faint grid pattern running through the brown kraft paper. That is the fiberglass reinforcement. According to our JLN series technical specifications, such as the JLN-3150 or JLN-3160, we sandwich these fiberglass strands between two layers of high-tensile kraft paper using a starch-based adhesive. This isn't just for show. When this tape is activated with water, that starch adhesive penetrates deep into the fibers of the corrugated carton. It doesn't just stick to the surface like pressure-sensitive plastic tape; it actually fuses with the box. This fusion creates what we call a tamper-evident seal. In the logistics world, theft and pilferage are silent profit killers. If someone tries to peel off standard plastic tape, they can often do it without leaving a trace, steal the contents, and press the tape back down. With the reinforced kraft tape shown here, removing the tape destroys the carton surface. You cannot open the box without leaving clear evidence. For our clients shipping electronics, pharmaceuticals, or high-value goods, this layer of security is non-negotiable. Beyond security, there is the efficiency factor. In the background of the photo, you see a warehouse environment where speed matters. Operators often use two or three strips of plastic tape to feel secure. With reinforced WAT, you only need one single strip down the middle. This is the One Strip, One Seal rule we advocate. It reduces material usage and speeds up the packing line, especially when paired with our KN series electric dispensers, like the KN-366H, which delivers the exact length of warm, activated tape instantly. Finally, we cannot ignore the environmental aspect. The tape in the photo is made from renewable resources. The kraft paper is natural, and the adhesive is starch-based. While the fiberglass reinforcement adds necessary strength for heavy loads—our heavy-duty versions like the KN-37120 are capable of holding significantly heavy boxes—we also offer solutions where the box remains recyclable. As global standards shift towards sustainable packaging, moving away from plastic BOPP tape to a paper-based solution helps companies meet their ESG goals while actually improving the structural integrity of their shipments. It is strong, it is secure, and it is the professional choice for modern fulfillment.

Stop fighting with hand-held tape guns.   If your warehouse is shipping more than 50 boxes a day, manual taping is costing you money—in wasted tape, slow speeds, and repetitive strain injuries.     Look at the photo above. This is the Kingnode KN-366BHP, an electronic water-activated tape dispenser. It sits quietly on the bench, but it changes the entire rhythm of a packing line. Here is why you need to upgrade.   1. The Magic of "Press and Go"   The Feature: See that keypad on the side? It’s not for calculation; it’s for precision. You want 60cm of tape? You press a button.   The Benefit: With a manual gun, employees guess the length. They pull too much (waste) or too little (insecure). With the KN-366BHP, the machine dispenses the exact length, moistened and cut, in under a second. No guessing, no fatigue.   2. Built for the Warehouse Floor   The Build: This isn't a flimsy office gadget. The KN-366BHP is designed with a large water tank and a robust heater (for cold environments) to ensure the glue activates perfectly every time.   The Workflow: Notice how clean the workspace looks in the photo? No tangled tape, no cutters lying around. It professionalizes your fulfillment station instantly.   Before you buy, here is what you need to consider:   Upfront Cost: This machine costs significantly more than a $10 tape gun. You need to view it as an investment (ROI), not a consumable expense.   Stationary vs. Mobile: While this model is compact, it is designed to sit on a bench. If your packers need to run around the warehouse to seal pallets in different corners, a handheld solution might still be needed alongside this.   If you want to move from "shipping boxes" to "professional fulfillment," the Kingnode KN-366BHP is the bridge. It turns a manual, messy chore into a fast, standardized process.   Ready to speed up your packing line? Ask us for a demo video of the KN-366BHP in action.  

Take a few seconds to really look at the photo above.   What do you see? No messy multiple layers, no shiny plastic glare, and no peeling edges. Just a single strip of tape that looks like it belongs there.   This is what we in the industry call "Integrated Packaging."   At JL3, despite all the tech advancements, Water-Activated Tape (WAT) remains our top recommendation for brands. Here is why this specific image illustrates three things plastic tape can never achieve.   It’s Fusion, Not Just Adhesion   The Difference: Standard plastic (BOPP) tape relies on pressure-sensitive adhesive to "sit" on top of the box. It’s a physical bond that weakens with dust or temperature changes.   The WAT Advantage: Water-Activated Tape works differently. The starch-based adhesive turns into a fluid when wet, penetrating deep into the cardboard fibers. Once dry, the tape and the box become one single unit.   Looking at the photo, you can see the texture matches perfectly. This "seamless" look makes your package feel premium, not cheap.   2. One Strip is Enough (Stop the "Mummy Wrapping")   The Bad Habit: Many warehouse packers have a habit of circling a box three or four times with plastic tape, fearing it might pop open. It’s wasteful and ugly.   The Reality: Look at the box in the picture. One single strip.   That is all you need. Because WAT creates a permanent bond, it provides structural rigidity that plastic tape can't. For standard shipments, a simple "I-seal" gets the job done. This cuts material costs and speeds up packing—no more running around the table to wrap a box.   3. Real Eco-friendliness Means Convenience   The Customer Pain: Modern consumers hate separating plastic tape from cardboard boxes to recycle them. It's a hassle.   The Solution: The packaging in the photo is 100% curbside recyclable. The tape is paper; the box is paper. They can be pulped together without separation. That small detail often wins quiet respect for your brand.   If your brand values aesthetics, security, and sustainability, or if you are tired of the screeching noise of plastic tape in your warehouse, the Water-Activated Kraft Tape in this photo is your answer.   Want your packages to have this "Premium Look"?
