Screws, nuts, washers and other small hardware parts are typically packed by piece count or weight. Compared with food granules, metal components have different handling requirements because of their hardness, weight and irregular shapes. Heavy parts can create impact during feeding and discharge, while sharp edges may increase the risk of damaging the packaging film or pouch.

For hardware products suitable for bulk feeding and pouch packaging, Runli can configure vertical form fill seal machines or premade pouch packaging equipment with appropriate feeding, counting or weighing, filling and sealing systems. The equipment and packaging materials should be selected according to component geometry, pack quantity or weight, and target output, with suitability confirmed through material and pouch testing.
