ZONESUN ZS-FS500K4 4-Lane VFFS Granule Packaging Machine Sachet Packing System with Vacuum Loader for Sugar Salt Coffee Stick

The ZONESUN ZS-FS500K4 is a high-speed automatic 4-lane vertical form-fill-seal (VFFS) packaging machine designed for free-flowing granules such as salt, sugar, sweeteners, saline packets, and water testing reagent sachets. It uses volumetric cup dosing combined with vacuum feeding for continuous operation, achieving around 120 bags per minute. The machine performs film forming, filling, vertical & horizontal sealing, cutting, and optional easy-tear notching and date coding in one integrated process. It is ideal for efficient, high-volume production of small sachets in food, seasoning, and chemical industries.

Key Features

• Touchscreen Control Panel – Intuitive touchscreen interface for easy management of multi-lane parameters, with support for multiple languages and quick recipe adjustments.
• 30L Hopper with Vacuum Feeding System – Large hopper equipped with level sensor and optional vacuum loader for automatic, continuous material replenishment.
• Swinging Cup Dosing Structure – Precise volumetric swinging cup mechanism ensures smooth and consistent granule dosing across all 4 lanes.
• Vertical and Horizontal Sealing Structure – Teflon-coated sealing rollers deliver clean, strong, and reliable seals while minimizing material buildup and wear.
• Rotary Cutting and Easy-Tear System – High-precision rotary cutter produces individual or connected sachets with optional easy-tear notches for user convenience.
• Date Coding Structure – Optional date coder prints production dates, batch numbers, or other information directly on the sachets during packaging.
