Product details
The WZ-129 bottom labeling machine is an inline labeling machine developed by Wanzhi Automation specifically for bottom (underside) labeling. It is suited to applying self-adhesive labels or protective film to the bottom of books, packaging boxes, cartons, bottles and cans, cups and other products. The labeling mechanism is arranged below the conveyor belt, so labeling is completed automatically as the product passes above. A printer and an inkjet coder can be integrated to print production date, batch number, barcode and other traceability information directly on the label surface. Conveyor width and positioning structure can be custom-built to order, and the fully automated continuous operation replaces manual turning of products for bottom labeling, greatly improving packaging line efficiency. It is widely used in volume bottom labeling for food containers, household chemical cans and gift box bases.
