What is perfect binding?

Perfect binding is a common bookbinding method where the pages and cover are glued together at the spine with a strong, flexible adhesive. It’s widely used for softcover books, catalogs, manuals, and high-end brochures.

What’s the difference between EVA and PUR perfect binding?

EVA (Ethylene Vinyl Acetate) and PUR (Polyurethane Reactive) are both adhesives used for perfect binding, but they differ in performance, flexibility, and cost. EVA is a traditional hot-melt, rubber-based adhesive that sets quickly—often within minutes—making it a faster option for production. It offers good binding strength and standard page pull resistance, though it performs best with uncoated paper stock and has moderate flexibility and temperature resistance.

PUR, on the other hand, is a reactive polyurethane adhesive that provides significantly stronger binding—about 30–40% stronger than EVA. It delivers superior page pull resistance, making pages less likely to fall out, and offers excellent flexibility, allowing books to open wider without stressing the spine. PUR also bonds well with coated, digital, and recycled papers and withstands extreme temperatures better than EVA. The trade-off is that PUR requires a longer curing time (24–48 hours) and is slightly more expensive per unit.

✅ When should I choose EVA?

• You’re printing short-run books or manuals that don’t need extreme durability

• Your turnaround time is tight and you need books fast

• The content isn’t expected to be opened flat or handled repeatedly

✅ When is PUR the better option?

• You’re producing high-value books or long-life publications

• The project includes coated, glossy, or digitally printed papers

• You want extra durability and resistance to temperature swings or heavy use

• You need a book that opens flatter and doesn’t crack at the spine
