Premium rigid boxes are some of the most commonly used and sought after boxes within the luxury packaging industry.

Rigid boxes differ from other boxes in a few key ways; most notably, material thickness, opening/closing experience, and manufacturing methods. Typically rigid boxes are four to five times thicker than traditional folded cartons and have many more options for opening experiences compared to corrugated boxes.

If you make rigid boxes, chances are you're pretty familiar with protein glue (animal glue). Have you ever run into a situation where the glue film becomes brittle and shatters? Today we dive into why this happens.

One of our most popular lines of rigid box glues in recent years has been our NW0500 series animal glues (protein glues).

Not only were these products designed by our technical team with equipment operators in mind, but we worked closely with rigid box equipment manufacturers to hit the nail on the head with this cost competitive line of glues. 

We recently visited with the rigid box equipment manufacturers at Emmeci USA to run some of our protein glues on their equipment. We always enjoy pushing our glues to the limit and seeing how they will perform in "real life" circumstances.
