Our about us page is really about you!
Interplas (International Plastics) is a family-owned flexible packaging supplier in Greenville, South Carolina. We've made packaging the easy part for businesses since 1964. Household names and one-person shops, same care either way.
We don't succeed unless you do.
Everything we stock and produce is aimed at one thing: your business success.
We're your packaging partner, not just a place you order from. If you don't get what you need, fast, and at a fair price, we haven't done our job. That's the whole standard. It's why our mission is simple to say and hard to do well: we help your business succeed by making packaging the easy part.
Sixty years, same promise.
In 1964, J.R. McClure borrowed $500 from his mother and bet on a material almost nobody understood yet. Greenville was the textile capital of the world, so he started where the work was. He turned polyethylene film into wicketed bags to package the yarn the mills around him were spinning. He and his wife Frances built the company one order at a time, grounded in his faith and a belief that how you treat people matters as much as what you sell.
Six decades later, the second generation is still here, blessed to steward what their parents started. They guide the company's direction while a strong team leads the day to day. Same family. Same values. Better systems every year.
How we treat people is the whole business.
We run on servant leadership and the Golden Rule. We do right by our customers, our vendors, and our associates, the same way we'd want it done to us.
That isn't a poster in the break room. It's why you get a real person on the phone, an honest timeline, and someone who owns the problem until it's fixed. Four words drive how we work. We call them the four P's, the pillars we're built on.
