Diamond Flexible Packaging has been a family-owned business since its start in 1929. Now in its third generation, our privately-owned company has seen much growth, but our core values remain the same.

Over the years the company has built a reputation for great customer service and high-quality products. It is thanks to our employees and our years of experience that we are one of America’s leading flexible packaging manufacturers. For almost 90 years, Diamond Flexible Packaging’s innovative packaging solutions have helped strengthen our customers’ brand and recognition.

We are proud to announce the addition of our UTECO ONYX 108 flexographic printing press to our lineup of printing presses. This machine’s capabilities offer the best in flexographic printing to our customers, showing our commitment to growth and increased quality.
