Metallocene-Based Hot Melt Adhesives
Are you curious about metallocene-based hot melt adhesives for packaging? Wondering if this newer adhesive technology is the best option for your specific application requirements? Trying to decide if you can justify converting from conventional EVA-based hot melt to metallocene hot melt? Here are some important considerations. Whether you spell it “metallocene” or “metalocene,” these adhesive formulas are the absolute highest performing adhesive technologies available for packaging. Metallocene-based hot melt adhesives virtually eliminate production downtime because they do not char like EVA-based hot melts so clogging of nozzles and filters are eliminated.
Plus, the density /specific gravity of most metallocene adhesives is lower than EVA adhesives so mileage is improved. Since the bonds produced with metallocene hot melts are stronger than bonds made with EVA adhesives, users can lower application rates improving mileage even more. Many users experience a 20% to 40% overall reduction in adhesive consumption using this technology. Lastly, metallocene adhesives produce bonds with high heat resistance and low temperature performance for freezer applications.
Metallocene-based hot melt adhesives for packaging are known by many trade names including Advantra from H.B. Fuller, ClearBond from Wisdom Adhesives and Technomelt Supra from Henkel. Bostik also offers metallocene adhesives. H. B. Fuller’s Advantra hot melts were the first metallocene adhesives in the industry due to an exclusivity agreement with Dow Chemical, but now virtually every adhesive manufacturer offers metallocene formulas to meet the most demanding packaging application requirements. These adhesive companies all use the same metallocene polymer in their formulations (Affinity from Dow Chemical). Since supply has increased, pricing for metallocene hot melt has come down significantly over the past few years. There is no reason to wait any longer to improve your packaging operations.
