Your Trusted UK Wholesale Packaging & Envelope Supplier
Postal Packaging started the way most good businesses do. A clear gap in the market, a small but determined team, and a lot of hard work. Founded by four women with years of experience in the packaging and envelope industry, we began selling from home and grew into a full warehouse operation in Cardiff, Wales. Today we supply businesses of every size across the UK and beyond, from independent retailers and e-commerce start-ups to large-scale fulfilment operations.
We stock everything you'd expect from an envelope and packaging supplier, and quite a bit you might not. Business envelopes, coloured and greeting card envelopes, padded mailers, board-backed envelopes and cardboard boxes, all available to buy online with competitive pricing and volume discounts of up to 40%. And if you're not sure what you need, that's fine too. Helping customers find the right solution is part of the job, and it's one of the parts we genuinely enjoy.
We care about helping you choose packaging that fits your needs. From size and material to closure and finish, our team can talk you through the available options. For businesses buying regularly, our Wholesale+ service brings exclusive pricing and 30-day credit terms to the table, and same-day dispatch means we move when it matters. We're rated Excellent on Trustpilot, and that's something we work to earn with every order.
