Trends in binding hot melt adhesives and polyolefin adhesives: In recent years, the binding industry has had to adapt to many changes, including increasing production line speed and adopting polyolefin (POE) adhesives. Which products can help you meet the demands brought about by these developments and why?
Hot melt adhesive for faster binding line speed
High-speed book production, especially when bonding book spines with adhesive at low application temperatures, poses many challenges to adhesives. Hot melt adhesive must provide a strong adhesive force, but it should set fast enough to avoid dirtying the equipment during the finishing process, thereby avoiding the costly production downtime required for cleaning.
Specifically designed for use as low as 140°C Formulated for application at temperatures, they will operate safely on rapid production lines, bonding up to ” 10000 & have spent A magazine or book spine.
Why do bindings turn to polyolefins? (POE) Adhesive
Another trend in binding hot melt adhesives is the increasing use of polyolefin adhesives to replace alternative technologies such as PUR.
“
and ” PUR Unlike adhesives, polyolefin adhesives do not release harmful isocyanate-containing vapors into the workplace, so there is no need for a dedicated emission recovery system or preventive measures. In addition, they offer a faster solidification time, require less cumbersome internal management due to their longer pot life, and do not need to clean the melt tank and applicator (nozzle/roller) after each use.
Compatible with most hot melt equipment and processed in general municipal waste, polyolefin adhesives do not require additional equipment investment or waste disposal procedures.
The benefits of handbag glue for food packaging: The use of hot melt glue is widely applied in various industries. Food is one of the areas where your application has experienced significant growth. We are now confronted with increasingly demanding consumers who demand elegant and practical packaging, high-end quality processing, and most importantly, respect for […]
With the development of science and technology, various multi-functional and high-performance adhesives have been increasingly widely applied in modern industrial fields and have become an indispensable material in modern industry and national defense industry. There are many types of adhesives. Judging from the current development and concepts, the adhesive industry is moving towards energy conservation, […]
Hot melt adhesive is also known as glue adhesive. They are thermoplastic polymer adhesives that are solid at room temperature. If heated to a temperature above its softening point, the hot melt adhesive will liquefy. Compared with various packaging components, their softening temperatures are relatively low. The liquefaction of hot melt adhesives allows them to […]
What causes white spots and bubbles in the adhesive layer? Directly provide the order of investigation:Moisture absorption of adhesive particles → high temperature of adhesive glue → stirring and rolling into air → surface moisture of substrate → suction of adhesive pumpAccording to this order, over 90% of the white spot bubble problems can be […]
