DiamondTop™ – where print performance meets consistency
Great packaging businesses never compromise the image targets of their customers’ brands and the efficiency of their operations, so the choice of paper they use is crucial. Great packaging businesses also know that the visual consistency of high-end substrates can make all of the difference in printing, quality, and repeatable images from run to run.
Discover the unparalleled performance of Smurfit Westrock’s white top linerboard products delivering unbeatable consistency for all your converting and printing needs. While our DiamondTop™ Uncoated has a white printing surface for printing high-quality graphics, our DiamondTop™ 1C coated white top liner is designed for high graphic users who need the ability to generate high print gloss and high ink density. It is post-printable without the aid of dryers yet suitable for the demands of high-end post printers, preprinters, and digital inkjet printers. Its end use spans retail-ready packaging, liquor and beer packaging, agricultural packaging, to e-commerce packaging.
Why choose DiamondTop™ 1C?
Aesthetics
Smurfit Westrock’s calendaring process and unique fiber composition result in the optimal smoothness of DiamondTop™ 1C, minimizing washboarding and fluting on the corrugated sheet. The superior smoothness, along with outstanding gloss, enhances the visual appeal of the final package.
Runnability
Our unique coating process and formulation maintain the flatness of our DiamondTop™ 1C sheet, minimizing paper warp and providing exceptional ink-holdout for high-quality graphics. The flatness of DiamondTop™ 1C enhances its runnability and convertibility on corrugators, enabling seamless performance on a full range of flexographic and digital inkjet presses.
Consistency
The use of virgin fiber and advanced manufacturing processes produces predictable performance in strength, brightness, and shade that translates to high integrity and visual vibrancy of the final printed package. And Smurfit Westrock’s continuous improvement programs and asset upgrades have enhanced our DiamondTop™ portfolio to meet market demands for consistency on critical board properties.
Assurance
With a network of two strategically located North American white top mills backed by a stable labor force, Smurfit Westrock guarantees reliable supply chain support for your business, with our mill footprint putting us closer to you. We now have additional white top capacity in Europe that can be leveraged if market conditions change, and our proactive Technical Service team can provide consultative product assistance spanning corrugation, printing, and conversion processes.
