Retrofittable leaf salad technology increases packaging rates and reduces seal contamination

11 November 2019

A technique that increases the bagging speed of leaf salads and reduces both film use and contamination levels can now be retrofitted to Vertical Form Fill and Seal machines. 

GIC, introduced its Leaf Salad Assisted Drop feature last year. It aims to eliminate upstream choking by creating an area of low pressure in the product chute which draws salad leaves down into the bag in one single slug. Without the feature, the product mass can elongate into several clumps of salad leaf, which increases the chances of causing contamination by being captured in the seal.
Until recently the Leaf Salad Assisted Drop technology could only be incorporated in new machines. However, GIC's engineers have now developed a way to fit the feature to machines that are currently running.
The retrofit includes all the mechanical and electrical parts plus a software update. The process takes around 8 hours to complete and, based on reports from current users, delivers around a 10% increase in productivity, and reduced seal contamination levels and downtime.
