PUR Binding: The Strongest Paperback Binding
When standard perfect binding isn't strong enough, PUR binding delivers unmatched durability with the same professional square spine paperback appearance.
PUR binding allows books to open wider without damaging the spine
What is PUR Binding?
PUR binding looks identical to standard perfect binding, but uses a different adhesive: Polyurethane Reactive (PUR) glue instead of the standard EVA (Ethylene Vinyl Acetate) adhesive.
PUR adhesive undergoes a chemical reaction with moisture in the air and paper fibres, creating an incredibly strong, flexible bond that's virtually impossible to break. Once cured, it can't be reactivated by heat, making it far more durable than traditional binding.
Key benefit: PUR binding offers 40-60% better resistance to page pull-out compared to standard perfect binding, while allowing pages to lay flatter.
Why Choose PUR Binding?
Superior Strength
Nearly impossible to pull pages out. PUR creates a bond that penetrates deep into the paper fibres for maximum durability.
Better Flexibility
Books open wider and lay flatter than standard perfect binding, making PUR ideal for workbooks and manuals.
Works with Coated Papers
PUR adhesive bonds effectively to coated, varnished, and UV-coated papers where standard glue struggles.
Temperature Resistant
Unlike EVA glue, PUR won't soften in heat or become brittle in cold. Your books stay intact from -40°C to 150°C.
When Should You Choose PUR Binding?
PUR binding costs slightly more than standard perfect binding, so it's worth understanding when the upgrade makes sense:
Heavy-Use Books
Workbooks, training manuals, textbooks, and any book that will be opened repeatedly benefit from PUR's superior durability.
Coated or Glossy Papers
Photo books, art books, and catalogues printed on coated paper need PUR for reliable adhesion.
Thick Books (300+ pages)
Larger books benefit from PUR's strength and flexibility, especially when the book needs to open properly.
Cross-Spread Images
If your design includes images that span across two pages, PUR's better lay-flat properties will show them better.
