PUR BINDING

If your document is too thick for saddle stapling or you’re after the traditional book format that sits and sorts on a shelf well then PUR binding is the perfect option. This method creates a solid, rugged document that’s easier to read and annotate than other options. It’s professional in appearance and incredibly cost-effective, even for low quantities. We refuse any glue other than PUR; as compared to the cheaper EVA it’s considerably more resilient to the environment, handling and storage. If you have a book for us with a lot of colour on the cover, especially near the edges we strongly recommended having your cover laminated to prevent damage from handling.

 
PUR Binding

PUR (polyurethane reactive) bonds differently with paper than EVA (ethylene vinyl acetate). PUR adhesives cure by cross linking via a chemical reaction with moisture contained in the paper stock or the surrounding air. As the PUR adhesive dries, a natural chemical reaction occurs after the glue is exposed to moisture in the air. This chemical reaction creates a superior bond within the fibres of the paper giving the product a greater pull and flex strength. This means that PUR bound books are very durable – it is almost impossible to pull a page from the bound book. It also allows the books to be laid flat when opened. PUR is also reliable glue for a wider range of stocks; it works well even with thick glossy coated paper. Finally, PUR bound books will last even under extreme temperatures.

Perfect Binding

We recommend PUR for any job printed on heavier than usual paper (>130 gsm) and on higher-value, digitally printed books that have to last longer than regular books. As an example, full colour children's books that are printed on a 150 gsm coated paper should be bound using PUR glue to make sure the binding lasts.
