Product Overview

The Keypack Intelligent (Kunbupack) SH-FX01 automatic case sealer combines international advanced manufacturing technology with premium imported components including electrical parts and pneumatic elements. Built on over ten years of carton sealing machine R&D experience, this machine incorporates cutting-edge technologies from Japan, Germany, and Italy to deliver reliable, high-performance box sealing solutions.

This automatic carton sealing machine features a compact and lightweight design with auxiliary wheels for flexible positioning, making installation and commissioning exceptionally convenient. The machine automatically folds carton top flaps and applies tape to both top and bottom surfaces simultaneously, ensuring fast, flat, and aesthetically pleasing seals. Equipped with blade protection devices, the sealer prevents accidental injuries during operation, prioritizing operator safety.

Designed with simplicity, economy, durability, and minimal failure rate as core principles, the SH-FX01 allows operators to manually adjust machine width and height according to carton specifications, making it ideal for sealing same-size cartons within the same production period. The machine can operate as a standalone unit or integrate seamlessly with automated packaging production lines, offering maximum flexibility for various packaging workflows.

Supporting three tape widths (48mm, 60mm, 75mm) and powered by a 220V, 400W motor with pneumatic assistance (0.4-0.6MPa), this corrugated box sealing machine delivers consistent performance with minimal maintenance requirements. The compact footprint (L1750mm × W850mm × H1500mm) and moderate weight (250kg) make it suitable for facilities with space constraints while maintaining industrial-grade durability.
