Handle Attachment and Handle Patch
In the bag manufacturing process, handles can be made of paper or string. Handles are attached to the patch with cold glue, hot melt or both. Th patch is then glued to the inside of the bag. Valco Melton manufactures high speed electric valves to ‘stitch’ the adhesive, placing it precisely where needed. Applicators are also available for applying lines of adhesive or full coverage. Combination cold glue/hot melt systems are beneficial as cold glue gives a strong bond while hot melt gives a fast tack to hold the handle/patch in place while the cold glue sets up.
