A new $2-million packaging line at the giant Jelly Belly Candy Co. has cut labor costs by 75 percent and reduced changeover times dramatically compared to other lines in the plant. During case closing, the cartons are conveyed past a Model 3138 trailing panel, print-and-apply labeler from Label-Aire Inc. that is integrated with a SATO America M8485Se printer, producing a UPC code and product-description label.
