Indianapolis, IN - Eckhart & Co., a leading resource for bookbinding services and custom packaging solutions in the Midwest, continues to expand its bookbinding division with the addition of a new Kolbus 7,000 cycles/hour perfect binding line.

PUR Binding vs. Perfect binding...Yes, they are different.  The biggest difference between the two types of binding is the adhesives that are used in the binding process.  PUR binding uses polyurethane reactive adhesives (PUR) and Perfect binding uses ethylene vinyl acetate adhesives (EVA).  At first glance, there is very little difference that can be noticed between the two.  However, PUR offers significantly increased binding strength...page pull tests are often 50% stronger with PUR than with EVA.   Additionally, PUR bound books lay much flatter than do Perfect bound books.

Which style to use for soft cover binding very much depends on the specifics of the project.   The type of paper, the spine thickness, and the intended use of the book all need to be considered.

"The summer of 2014 has been very exciting here at Eckhart & Co.  In addition to our Kolbus binding line we recently installed new film laminating equipment, as well as new diecutting and stamping equipment.  It's been our goal since day one to help our customers grow their businesses.  The major capital investments that we have made in the business are all aligned to support that goal." commented President Chris Eckhart.
