Pinch Bottom Bags
Pinch bottom bags are generally multi-wall paper bags that have a flap on each end, with a ribbon of hot melt adhesive applied. The bottom is sealed immediately, while the top is left for the end customer to seal after filling. Valco Melton manufactures hot melt ribbon applicators specifically designed for this application. Another option is cross web hot melt application on the tuber itself. This could potentially eliminate the need for the secondary pinch bottom application. Valco Melton manufactures high speed, hot melt ‘patch’ and cross web coating heads for these applications. To find out which solution is right for you, contact us today.
