PURfect Binding

Our PUR perfect binding machine creates superior Perfectly Bound Books.


So what’s PUR and how does it compare to EVA (hot melt adhesives)?

Some of the many Benefits of a PUR perfect bound book:

  • It has superior adhesion.
  • Especially helpful for difficult coated paper stocks, UV coated, aqueous coated text only.
  • Heat and cold resistant - it stays flexible in cold temperatures.

    Covers: no coatings on inside of cover or knock out spine + 1/4” hinge x 2 area width. Get the full scoop here.

do not coat (UV) the covers. ”No cold” lamination for covers. MUST be applied with "HOT seal " lamination. The cold lamination process sits on top of the sheet. Also, with the cold when we score, the film delaminates.The HOT process seals with the toner/fibers.  Click here for more information about lamination
