PUR perfect binding
Durable soft-bound books, catalogs, directories and manuals, bound in-house alongside web printing, finishing and USPS mailing.
Why choose PUR binding
When you need the best in quality and durability, make it last with PUR. With the latest in PUR technology, Liberty Press offers a superior alternative to traditional perfect binding.
- PUR (polyurethane reactive) adhesive bonds into the paper fibers instead of sitting on the surface, so pages hold up to repeated use.
- Books open flatter than standard hot-melt perfect binding.
- Grips coated, gloss and UV-coated stocks that can repel standard glue.
- Stays stable in heat and cold, so copies survive the mail and the warehouse.

PUR or standard perfect binding?
Liberty Press runs both, so we recommend what fits the job. Standard (EVA) perfect binding costs less and suits short-shelf-life publications such as monthly or quarterly magazines on uncoated stock. PUR costs more in the binding line item, but it is the most durable soft-cover option and the better choice on coated paper or for pieces people keep.
PUR cures over several hours rather than seconds, so we build curing time into the schedule before addressing, polybagging or mail entry. Ask us to quote both options on identical specs. For a detailed comparison, read our guide to PUR binding vs perfect binding.
Finishing and mailing under one roof
PUR-bound work can move straight into the rest of our plant: embossed and foil-stamped covers, shrink-wrapping, addressing, polybagging and tip-on cards and magnets. As a USPS detached mail unit, we verify mailings in-house, and we can warehouse and ship remaining copies by truck, air or rail.
Common questions
Is PUR binding stronger than perfect binding?
PUR is a type of perfect binding that uses polyurethane reactive adhesive instead of standard hot-melt (EVA) glue. It bonds into the paper fibers, so pages generally hold better, especially on coated stock and in hot or cold conditions.
Does PUR binding cost more?
Yes, PUR adds to the binding line item. On a long web offset run, printing and paper usually drive most of the cost, so compare quotes for both options on identical specs.
How long does PUR take to cure?
PUR cures through a reaction with moisture and can take up to about 24 hours to reach full strength, so curing time is planned before trimming, mailing or shipping.
What should I send for a fast PUR binding quote?
Quantity, page count plus cover, trim size, paper stock, any cover finishing, and whether the job mails. Also tell us when files will be ready. You can call 801-853-5353 or use the online quote form.
