About Us

Partners and Problem Solvers

At Yorker Packaging, we make our purpose clear: to be the ones with the answers. Our expertise and award-winning products give our clients the confidence they desire and the real-world solutions they depend on.


Since 1942…

Yorker Packaging has been devoted to overcoming challenges across design, engineering, and manufacturing. After being acquired in 1989 by Alltrista Plastics, formerly known as Jarden Plastic Solutions and Unimark Plastics, we moved from Denver, Colorado to the beautiful Upstate of South Carolina. At our Greer facility, each and every Yorker Packaging cap, closure, and custom product is designed, manufactured, and shipped. And with 31 injection molding lines working 24/7 to meet customer demands, as well as the leadership of Alltrista's material science experts supporting our product development, it’s no wonder that so many brands across so many markets depend on our award-winning custom designs and engineering solutions.


To Value and Be Valued

"Adding value to others is the surest way to add value to our own lives."

John C. Maxwell

Our promise to clients has always been a product plus value. These achievements are responsible for giving our everyday work meaning. But this isn’t just our approach to work, it's our approach to people—especially the talented members of our own team. We're committed to bringing value to their lives through learning opportunities, listening to and implementing their ideas, and creating paths for them to lead and explore. When they grow, we grow.


We believe we will only thrive when we go after our goals together. By listening, supporting, and depending on one another's unique strengths, we will always evolve together.


We're committed to applying the highest standards of quality to our products, processes, and people. We strive to be the best we can be, as a unit and as partners.


We're reliable because we're responsible. Across all of our teams, we nurture a culture of diligent work and deliver on promises.
