Folding Carton Manufacturing
In order to produce truly exceptional cartons, you need truly exceptional equipment. While the nuts and bolts of folding carton die cutting involves the use of specific die cylinders and rotary machines that fold, crease, cut, stamp and label cartons, the key to increased performance, efficiency, and thereby cost-savings are making sure the various parts are all working together. That’s where our Folding Carton Systems truly shine.
We offer state-of-the-art designs for unwinds, prefeeds, decurls, cutter infeeds, rotary modules, skew belts, shingle deliveries, fan-wheel stackers, and receding pile stackers. We’re in the business of supplying total converting systems, beginning with our world-class and highly regarded rotary dies and modules. We take full responsibility for your entire project, from design, R&D, and manufacture through service and ongoing customer support. This includes working with you and your team on designing new applications for the ever-evolving folding carton industry. The folding carton systems we make here at Bernal achieve highest speeds and efficiencies possible today, and we’re constantly building upon our tradition of excellence to gain even more speed and efficiency in the systems we’ll create tomorrow.

Flexible vs. Solid Rotary Dies. What’s the Difference?
There are two types of rotary dies: flexible and solid. Rotary die cutting involves either a flexible or solid rotary die. These dies are both cylindrical dies. A flexible die is made of a thin sheet of steel, and wraps around a magnetic cylinder. A solid die is a solid steel cylinder, and is traditionally used in more long run applications for extended die life. Bernal develops solid rotary dies for converting and product manufacturing applications throughout many industry sectors.
Creasing is an operation which facilitates the folding operation. During this process, the paperboard is weakened along well defined folding lines, which then act as hinges for folding packaging and graphical products. Without creasing the surface, plies...read more
Bernal RP® rotary dies represent a breakthrough technology in the folding carton industry for solid rotary tooling. These dies provide significantly longer die life over conventional rotary dies while maintaining cutting quality and minimizing waste by...read more
Bernal invented the solid hardened rotary die in the late 1960s by creating a wedge-type cutting edge on a solid cylinder through the use of EDM (electric discharge machining). Our proprietary process allows us to precisely manufacture dies, thereby...read more
