The KN-1717U semi-automatic water activated tape case sealer addresses packaging operations where box dimensions remain relatively consistent and manual adjustment is acceptable within the production workflow. Unlike fully automatic models that require integrated sensing systems, the KN-1717U relies on operator-controlled height and width adjustments, making it suitable for facilities processing uniform carton sizes or operations with longer production runs of single SKUs.   The machine accommodates standard tape core inner diameters of 38 mm, 48 mm, and 76 mm, with a maximum tape diameter capacity of 500 mm. This specification aligns with our reinforced water activated tape product range, ensuring compatibility across light, medium, and heavy-duty grades. The manual adjustment mechanism allows operators to position the tape head according to carton dimensions, which requires initial setup time but maintains consistent application once calibrated. For operations sealing identical box sizes throughout a shift, this configuration provides reliable performance without the complexity of automated sensing systems.

The KN-1721R is a fully automatic water-activated tape sealing machine designed specifically for modern packaging production lines. This machine utilizes an intelligent sensing system that automatically identifies the height and width of cartons, quickly adjusting to the optimal sealing position without manual intervention, significantly reducing changeover time and improving overall packaging efficiency.   The machine is compatible with 38mm, 48mm, and 76mm (1.5-inch, 2-inch, and 3-inch) standard tape cores and supports tape rolls with a maximum diameter of 500mm, minimizing downtime from frequent tape changes. When used with water-activated tape, the starch-based adhesive forms a strong bond with the carton fibers, providing excellent sealing performance and tamper-proof protection while ensuring the environmental friendliness of the packaging materials.   This model is particularly suitable for e-commerce fulfillment centers, logistics hubs, and various manufacturing enterprises, capable of reliably handling corrugated cartons of different sizes to meet high-throughput packaging demands. Compared to our other self-developed semi-automatic model, the KN-1721R eliminates operational errors and efficiency bottlenecks caused by manual adjustments, providing enterprises with an efficient, environmentally friendly, and reliable automated sealing solution.
