Who Are Postal Packaging?

At Postal Packaging, we're all about providing sustainable, top-quality packaging solutions for businesses of every size. With over 20 years of experience combined and a deep understanding of the industry, our team
is here to offer you the best service possible in the UK, running on coffee, yoga poses, and a 90s dance playlist!

Our journey began with four determined women who shared a vision. With our experience in the packaging industry, we decided it was time to venture out on our own. Starting with just six team members, we were small but mighty. We rolled up our sleeves and learned to drive forklifts, built muscles from unloading countless containers, and became experts with a mallet while constructing our shelving. We started off selling on eBay from one of our homes, and soon enough, we moved into our very own warehouse.
