Efficiency, Sustainability, and Automation — Fully-Automatic WAT Case Sealer: The New Powerhouse in E-Commerce Logistics     In today’s rapidly evolving e-commerce and logistics landscape, traditional manual case sealing methods are no longer sufficient to meet the demands for efficiency, standardization, and sustainable packaging. A growing number of businesses are turning their attention to a new category of equipment — the Fully-Automatic Water-Activated Tape (WAT) Case Sealer, a smart solution that is becoming an essential part of modern packaging lines.   What Is a WAT Case Sealer?   A WAT case sealer is an automated sealing machine designed specifically for use with Water-Activated Tape (WAT), also known as gummed kraft paper tape. Unlike conventional sealers that rely on BOPP plastic tape, this machine uses an automated moistening system to activate the tape’s adhesive properties, enabling fast, clean, and secure sealing.   This type of equipment is especially favored in e-commerce fulfillment centers, cross-border logistics warehouses, and 3PL service providers for its stability, efficiency, and eco-friendly nature.   Key Advantages   Intelligent Moistening System   Built-in humidification automatically activates the tape without manual intervention, ensuring continuous and stable operation.   Strong and Neat Sealing   Water-activated tape offers superior adhesion and tamper-evidence — once sealed, boxes cannot be reopened without leaving visible damage. This ensures security while providing a clean, uniform appearance that enhances brand image.   Eco-Friendly Materials   WAT uses recyclable kraft paper and starch-based adhesive, unlike conventional plastic tape that’s difficult to recycle. This aligns perfectly with the global shift toward sustainable packaging.   Fully Automated Operation   Supports high-speed, one-touch operation, making it ideal for bulk order processing and integration with automated sorting and packing lines. It significantly reduces labor costs and human error.   Application Scenarios   E-commerce Fulfillment Centers (e.g. Shopee, Amazon, JD.com)   Third-Party Logistics (3PL) Automated Packaging Lines   Overseas Warehouse Sorting Centers   Medium-to-Small Parcel Packaging (Food, Daily Goods, Apparel)   Green Packaging Transitions in Manufacturing   Product Highlights    JL’s Fully-Automatic WAT Case Sealer Series Offers:   Smart carton size recognition with auto-adjustable height and width   Compatibility with 38mm, 48mm, and 76mm tape cores   Max tape roll diameter up to 500mm, suitable for extended operation   Can be integrated with case erectors, labelers, and palletizing systems for a complete packaging line   Conclusion   The Fully-Automatic WAT Case Sealer is revolutionizing packaging efficiency and sustainability. It’s...

Filament Tape: The Preferred Solution for High-Strength Strapping and Industrial Packaging     In high-load environments such as transportation, warehousing, and manufacturing, traditional tapes often fail due to inadequate tensile strength or unstable adhesion. This is where Filament Tape—known for its exceptional tensile strength and reliability—has become the go-to packaging solution for industrial and logistics applications.   What Is Filament Tape?   Filament Tape is made from a BOPP or PET film base embedded with high-strength glass fiber or synthetic fiber as reinforcement. It is coated with synthetic rubber or hot melt adhesive. This engineered structure gives the tape superior tensile strength and outstanding adhesion, making it ideal for heavy-duty strapping and industrial sealing tasks.   Four Core Advantages That Make It Stand Out   Exceptional Tensile Strength   Reinforced fiber construction ensures the tape resists breaking under tension, making it a reliable alternative to strapping bands for securing heavy loads and industrial packaging.   High Adhesive Power – Firm and Long-Lasting Bond   The synthetic rubber adhesive enables strong bonding even on rough or irregular surfaces, preventing peeling or cracking during transportation.   Versatile Strength and Size Options   Available in light-duty, medium-duty, and heavy-duty grades with varying thicknesses, widths, and adhesive types to meet packaging needs from everyday applications to specialized industrial use.   Wide-Ranging Application Compatibility   Whether bundling steel, oil pipes, and cables, or securing household appliances and electronic components, Filament Tape delivers consistent performance across industries.   Broad Application Scenarios   Industrial Packaging: Firm bundling of mechanical parts and metal materials   Logistics and Shipping: Prevents shifting of heavy goods during transit   Appliance Transportation: Secures refrigerator and washer doors during delivery   Electronics: Bundling of wires and battery modules for stable transport   Construction and Infrastructure: Tying chemical pipelines and bridge components   Diverse Product Lines to Meet Custom Needs   The JL Series of Filament Tapes includes a wide range of base films (BOPP, PET), adhesive types (synthetic rubber, hot melt, acrylic), and reinforcement materials (glass fiber, synthetic fiber). These tapes offer excellent elongation rates (typically 3–5% or higher) and are available in three strength levels: light, medium, and heavy-duty—ready to match your specific application.   We also offer special-function versions such as high-temperature resistant, printable, and flame-retardant tapes, designed to meet the demanding standards of industries like construction, power, and aerospace.   Filament Tape Is More Than Just a Bonding Tool—It’s the &ldquo...

Why Are More Companies Switching to Water-Activated Tape (WAT) Instead of BOPP Tape for Carton Sealing?     In the packaging industry, carton sealing tape plays a crucial role in protecting the contents inside. It directly impacts parcel security, brand image, and a company’s environmental responsibility. In recent years, Water-Activated Tape (WAT) has rapidly emerged as a preferred alternative to traditional BOPP tape, becoming the sealing solution of choice for many forward-thinking brands.   So, What Makes Water-Activated Tape Superior? And What Scenarios Is It Best Suited For? Let’s Take a Closer Look.   One Strip Is Enough: Stronger Sealing Strength   Made from kraft paper and reinforced with either plant-based fibers or fiberglass, WAT uses a starch-based adhesive that securely bonds with the carton surface upon activation with water. Compared to traditional BOPP tape, it offers higher tear resistance and sealing integrity. It is difficult to tamper with or peel off, making it ideal for secure carton sealing in logistics and anti-theft applications.   Eco-Friendly and Hassle-Free: Recyclable and Biodegradable   Primarily composed of natural materials, WAT can be recycled together with cardboard boxes—no need to separate the tape from the carton like BOPP tape. Some variants are made from recycled kraft paper, supporting sustainable packaging efforts and aligning with companies’ green initiatives.   Professional and Clean Appearance: Elevating the Packaging Aesthetic   WAT adheres smoothly without curling or bubbling, resulting in a clean and uniform look. This enhances the visual appeal of packages, making them look more professional—an important advantage for e-commerce and premium retail brands focused on customer unboxing experience and brand presentation.   Efficient Sealing: Streamlining the Packaging Process   Thanks to its strong adhesive properties, only a single strip of WAT is needed for a secure seal—eliminating the need for double-taping. When used with a dispenser featuring smart cutting and auto-feed functions, the sealing process becomes highly efficient, saving time and labor.   Versatile Range: Suitable for Various Applications   WAT is available in a wide range of strength levels to accommodate different carton weights and packaging needs:   Options include fiberglass-reinforced or eco-friendly plant fiber types;   Adhesives come in starch-based or hot melt variants;   Recycled paper series are available for more budget-conscious packaging.   Jialong's Water-Activated Tapes Meet Diverse Needs Including Sustainable Packaging, Heavy-Duty Sealing, and Custom Printing.   Whether you’re a large logistics company seeking operational efficiency, or a brand focused on eco-conscious practices and customer experience, WAT is a powerful new alternative worth exploring. It not only enhances the quality of...
