Our customers regularly ask us to consider and explain the merits of PUR binding over Perfect binding. These considerations are often made against a backdrop of performance and ever increasingly, price constraints. With this in mind, let’s consider the differences between PUR and perfect binding and try to contextualise when it is appropriate to PUR bind or perfect bind.
The fundamental difference between the two types of binding is the adhesive used in the process. Perfect binding uses ethylene vinyl acetate (EVA) adhesives whereas PUR uses polyurethane reactive (PUR) adhesives. Put simply, the binding really only differs by way of the type of glue used. It is the properties of each type of adhesive, however, which is important in determining which is suitable.
