Only Stan's " The Secret Shelf"

At Poly Postal Packaging, we’ve always done things differently. For years, we’ve offered non-standard and oversized mailing bags that no one else stocks off the shelf — including our unique PPP-13, PPP-14, PPP-15, PPP-16, PPP-17, PPP-19 and PPP-21 grey mailers. We were the first to launch a 90mu heavy-duty grey mailer and remain the only supplier to offer it directly. Our Baby Blue mailers feature exclusive sizes, and our colour selection is unrivalled — including Brown, Beige, Cream, and Burgundy mailers from stock. We also stock the largest range of clear self-seal LDPE bags in the UK.

Our printed Eco Tapes come with exclusive designs that make sustainable packaging stand out. Our LDSB and RSLDSB self-seal bags are long-standing customer favourites, and the Olive Green Mailers are another hidden gem in our range. At Poly Postal, we focus on releasing packaging that doesn’t just look good but works hard — for start-ups, independents, and trade buyers alike.
