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.

Coating specs for outside covers:

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
