Coating Defects and Resolution for Hot Melt Adhesive Coating

Overview:

As coating corporations work toward increasing margins, getting more out of the capital equipment  at the site, improving turns in inventory, and reducing environmental impact, they are running into the edge of material, expertise, and equipment capability.  Hot melt adhesive coating is a great option for traditional solvent-based tape and label manufacturing, especially as  the “green” label is providing a marketing edge in commerce.  But what are the limitations? How thin can an adhesive be stretched before the rheology of the polymer is detrimental to the final product? How do you best operate the equipment to maximize product yield?  What are the common defects in hot melt coating with slot die equipment? This presentation will exhibit the current direction hot melt adhesive manufacturing companies are headed and what the impact is for raw material suppliers and roll-to-roll coaters.
