Why upgrade your salt packaging line

Manual weighing and sealing often cause weight deviation and weak seals, while open handling risks moisture pickup and contamination. Our automated solution raises throughput to 100–150 bags per minute, holds weight accuracy within ±0.3 g, and ensures closed transfer from hopper to finished bag for hygiene compliance.
