📖 The glue holding your book together might be the most important thing about it that you've never thought about.
Most POD softcovers use EVA hot-melt adhesive. It's cheap, it's fast, and it works—until it doesn't. EVA becomes brittle in cold temperatures, softens in heat, and weakens with repeated opening. That's why POD paperbacks crack at the spine, shed pages, and feel like they're one aggressive read away from falling apart.
PUR adhesive is a completely different chemistry. It forms a permanent cross-linked bond that's stronger, more flexible, and resistant to temperature changes. A PUR-bound softcover opens cleanly without cracking, holds pages securely through hundreds of reads, and doesn't degrade over time the way EVA does.
The difference isn't visible on the shelf. It's felt the moment a reader opens the book—and every time after that.
At PRC Book Printing, PUR glue binding is standard on our perfect bound softcovers. It's one of those production decisions most authors don't know to ask about—but it's the difference between a book that lasts and a book that doesn't.
