Who We Are
Family Run Business Since 1957
When my father, John P. Cheever, founded J.P. Plastics in 1957, he set out to do something simple and surprisingly rare: make quality custom thermoformed plastics right here in America, and stand behind every part that left the building. Nearly seventy years later, that promise still guides everything we do.
​
I grew up around this company, and I have seen firsthand what it means to earn a customer's trust one order at a time. I am proud to carry my father's work forward as the next generation of our family to lead it.
​
A great deal has changed in our industry since 1957. Materials, machinery, and the needs of the customers we serve continue to evolve, and we have grown right along with them. What hasn't changed is how we treat the people who count on us.
Â
We still believe in dependable service, competitive pricing, and delivery you can plan around. We still make our products in Bridgewater, Massachusetts. And we still build each solution around your needs rather than asking you to settle for something off the shelf.
​
From clamshells and blister packaging to handling trays, box inserts, custom tooling, and fully thermoformed products, our team treats every project, large or small, with the same care my father brought to his first. That is the difference a family-owned company can offer, and it is a difference we intend to keep.
​
Whether you are launching a new product or looking for a more dependable partner for an existing one, I invite you to see what J.P. Plastics can do for you.Â

Our Clients
We believe each client is a long term partnership
For over sixty years, J.P. Plastics has treated every client like a partner, not a purchase order. As a family-owned company, we are small enough to know you by name and experienced enough to guide your project from the first sketch to the final production run. When you bring us an idea, our team works right alongside you to shape it, drawing on decades of experience to steer you toward the best design and the smoothest path to production. We handle the details so you do not have to. And long after the first order ships, we are still here, because we treat your success as our own.
"J.P. has been our go-to for custom trays for years. The quality is consistent run after run, and when our volume jumps unexpectedly they always find a way to keep us on schedule. It feels like having a partner, not just a supplier."
Operations Manager
"Reliability is everything for us, and J.P. delivers. Clear communication, honest lead times, and they stand behind every order. In years of working together they have never once let us down."

"Working with Leanne and Karen always puts us at ease. They stay on top of our orders, are quick to answer a question, and genuinely invested in getting things right. You do not find that kind of care and attention everywhere, and it makes all the difference."
