Sonoco Introduces New Process for Metallic Finish

Sonoco worked with its graphics management and tooling business, Trident, and with a global manufacturer of metallic pigments to find a cost-effective and sustainable way to achieve its mirror-like finish for flexible packaging. By optimizing cylinder parameters to more efficiently transfer ink, and identifying the correct adhesives to prevent degradation of the pigment on the substrate, Sonoco discovered a metallic ink printing process unlike any in the marketplace.
