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.
General conclusion:Standard spot models can be shipped within 1-3 days, non-standard customized or color matching models within 7-15 days, and export orders with third-party testing reports within 15-25 days.But this is just an ideal state, what really determines when you can turn on is the following 8 factors. By checking them one by one, the […]
When pasting hardcover book cover cloth (flower cover cloth on both ends of the spine), it should be selectedHot melt adhesive particles for book and magazine binding with high initial adhesion, short opening time (3-6 seconds), and softening point of 80-95 ℃This process requires a small amount of glue, a narrow area, and quick positioning. […]
What do we need to inspect when replacing the adhesive particles for book and magazine packaging and making samples? Directly provide the list: When changing the glue or selecting a new supplier, a sample must be made and checked before formal productionAdhesive strength, page flipping flatness, appearance of book back, temperature resistance, opening time, odor, […]
Recycled kraft paper boxLow surface energy, high dust content, and easier detachment after moisture absorptionDirectly applying the sealing glue of the original cardboard box often opens the glue. The conclusion is:The regeneration box should be selected with “high initial adhesion, moisture resistance, and moderate penetration” sealing special rubber particlesAnd perform surface treatment before applying glue.
