JL3 Solutions for Structural Reinforcement and Jobsite Safety   In large-scale infrastructure projects like bridge construction, material selection plays a crucial role in structural safety, construction efficiency, and long-term durability. While tape is often associated with everyday packaging, industrial-grade functional tapes are indispensable tools in professional construction settings.   JL3 offers a wide range of industrial tapes that are widely used in bridge projects—for temporary holding, surface protection, structural reinforcement, vibration damping, and more—providing dependable support for construction teams. Five Key Applications of Industrial Tape in Bridge Construction   1. Temporary Holding & Positioning   During concrete casting or steel assembly, tape is often used to temporarily hold components, covers, or wiring in place. JL3’s unidirectional filament tapes, such as JLT-605 and JLT-607M, feature high tensile strength and abrasion resistance, maintaining stable positioning without slippage.   2. Surface Protection   Before painting or welding, certain components must be shielded from dust, moisture, or welding spatter. JL3’s clean-removal, high-adhesion tapes like JLT-615 and JLT-695 provide reliable protection without leaving adhesive residue on steel or concrete surfaces.   3. Safety Marking   Clear, visible markings are critical during elevated or nighttime operations. JL3 offers colored high-strength fiber tapes and custom-printed warning tapes to improve visibility on-site and reduce safety risks.   4. Structural Reinforcement   To prevent components from loosening due to vibration, shock, or tension during construction, bi-directional filament tapes like JLW-302A and JLW-329 provide additional support, ensuring stability during transport and assembly.   5. Vibration Damping   In high-temperature, high-pressure equipment environments, structural interfaces may experience significant vibration. JL3’s double-sided tapes, such as JLW-315, used with foam layers, help absorb vibration energy—extending the life of equipment and the structure itself.   Why Choose JL3?   Decades of experience in industrial-grade tape development and manufacturing   Products engineered for demanding environments (high heat, humidity, heavy loads)   Support for sample testing, technical consultation, and bulk custom orders   Tapes can be customized for slitting, printing, and integration with construction workflows   Final Word: Small Tape, Big Impact   In large-scale engineering projects like bridge construction, industrial tape is no longer just an accessory—it plays a direct role in quality control and construction efficiency. Choosing the right tape reflects both your professional standards and commitment to safety.   To learn more about how JL3 tapes can support your construction project, or to requ...

A Professional Guide to Carton Sealing Carton sealing plays a crucial role in e-commerce shipping, warehouse sorting, and logistics for manufacturing.

Opt for degradable or recycled series   Using sealing equipment? JL3 tapes are fully compatible with our dispenser systems   Final Thought: The Right Tape Reflects Professionalism   Whether you're an e-commerce brand, a manufacturer, or an export trader, the right choice of tape doesn’t just affect packaging efficiency—it also reflects your commitment to customer experience and corporate responsibility.   JL3 offers a complete line of kraft paper tapes, with customizable printing, size options, and reinforcement solutions to help you upgrade your packaging to be more efficient, sustainable, and reliable. ...

Water-activated tape (WAT) is rapidly gaining popularity among courier services, e-commerce platforms, manufacturers, and exporters due to its eco-friendly nature. But is it truly worth adopting? This article will help you explore its working principles, advantages, usage recommendations, and JL3 product model suggestions from multiple perspectives. Ready? Let’s dive in! What Is Water-Activated Tape, and How Does It Work?   Water-activated tape is a new type of eco-friendly packaging tape made from kraft paper and starch-based adhesives. Its adhesive properties are activated only when moistened . Once applied to a carton surface, it "fuses" into the cardboard fibers, creating a permanent, tamper-evident seal that cannot be peeled open without damage.   Unlike traditional plastic tapes (e.g., OPP), it does not rely on synthetic solvents and leaves no sticky residue or pollutants. This sealing method offers significant advantages in terms of environmental sustainability, safety, and durability.   When Should You Consider Using Water-Activated Tape?   1. You need to seal lightweight or medium-weight boxes for export to countries with strict environmental regulations.   2. You aim to enhance your brand’s professional image and eco-friendly credentials.   3. You worry about tape loosening or peeling during transit.   4. You require a non-resealable, tamper-proof solution.   5. You plan to integrate it with automated taping equipment or dispensers to improve efficiency. Benefits of Water-Activated Tape：   1. Stronger Adhesion The water-activated adhesive bonds permanently with cardboard fibers upon application. For example, JL3’s JLN-870 maintains strong adhesion throughout transportation, resisting vibrations and impacts.   2. Higher Load-Bearing Capacity Reinforced models like JLN-8140 and JLN-39150 , embedded with plant fibers or glass fiber layers, are ideal for heavy-duty shipments (e.g., industrial parts, electronics, furniture).   3. Eco-Friendly 100% plastic-free, recyclable, and biodegradable. Models like JLN-39140 , JLN-39150 , and JLN-39160 (with plant fiber reinforcement) meet EU green compliance standards and Amazon’s sustainability requirements.   4. Superior Waterproofing and Weather Resistance Maintains adhesion even in humid, rainy, or snowy conditions, outperforming traditional OPP tape.   How to Use Water-Activated Tape？   Using water-activated tape requires a dedicated dispenser. JL3 recommends the following:   KN-266 (Manual Model): Suitable for small batches or low-frequency use.   KN-366H Series (Electric Model): Features automatic cutting, counter, and moistening functions. Available with UL certification, battery-powered options, or heavy-duty versions.   KN-1721R (Automatic Carton Sealer): Integrates with production lines for large-scale warehouses.   After installing the dispenser, simply add water, load the tape ...
