Baldwin’s flagship brand Ahlbrandt® is a world renowned manufacturer of corona treatment systems for printing and industrial applications such as film and sheet extrusion, and textiles.
Our systems offer key features and benefits that set them apart from the competition by providing ease of service and reliability that is simply unmatched. A key differentiator: Ahlbrandt systems use four electrodes instead of the common “2-up” design, which dramatically improves treatment results.
How It Works:
Corona treatment systems work by increasing the surface energy of materials like plastic films, papers and foils, so that they can be printed on or coated with perfectly uniform results and effective adhesion.
Ahlbrandt’s premium quality German-made systems are known around the world as the leading corona treatment solution for the printing and film extrusion industries - they are also used in converting, narrow-web flexography, parts manufacturing and a host of other applications.
For years Ahlbrandt’s Corona systems has been the proven standard solution for the surface-wide handling of plastic films, metalized films, paper and textiles in Europe. Its unique “four-up” electrode design requires only one housing, a superior design feature that differentiates it from other solutions on the market.
Since Baldwin acquired Ahlbrandt in 2017, these products are now readily available and serviceable internationally, with ample product-support resources now established in the North American market.
Noteworthy Benefits:
Achieve the dyne levels needed for application of inks, coatings, etc. on nonporous substrates
Quick electrode changes and “cuttable” electrodes provide a unique advantage with Ahlbrandt corona systems
