PUR BOUND BOOKS
PUR bound books use EVA (ethylene vinyl acetate) adhesive to allow the bound book to lay flat without compromising the binding strength. PUR binding has some distinct advantages over perfect bind. PUR glue is the most durable binding glue available, resistant to degradation under extreme temperatures. This means that PUR bound books can be used anywhere â€“ from the hottest summer heat to the most harsh of winter conditions â€“ without unwanted re-melting or cold cracking.
