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 ecommerce startups 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, cardboard boxes and eco-friendly alternatives, 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 getting it right on every front. Recycled and compostable options sit alongside our standard range because sustainability should be an easy choice, not an awkward one. 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.

The moment a package arrives is no longer the end of the customer journey. For many brands, it's the first physical interaction a customer will have with them — and it carries more weight than ever before.
Earth Day Special: Sustainable Packaging Solutions
Every year on 22nd April, millions of people around the world unite to celebrate Earth Day — a global movement dedicated to environmental protection, climate awareness, and positive change. Since its beginning in 1970, Earth Day has grown into one of the largest civic observances on the planet, inspiring individuals and businesses alike to take measurable action toward a more sustainable future. At Postal Packaging, we believe that small, everyday decisions — including the packaging materials we choose — can have a significant impact. This Earth Day, we're highlighting the importance of sustainable packaging and the steps we're taking as a business to reduce waste and support a greener planet. Why Earth Day matters Earth Day serves as a reminder that the resources we rely on are finite and that our environmental footprint matters. The initiative encourages: Waste reduction Responsible consumption Carbon footprint reduction Conservation of natural resources Support for renewable and recyclable materials "Packaging is one of the most widely used products in everyday life. By making eco-friendly choices, businesses and consumers can significantly reduce pollution, landfill waste, and the consumption of non-renewable materials."

Our own sustainable practices Sustainability isn't just about what we sell — it's also about how we operate. At Postal Packaging, we've introduced several eco-forward practices to reduce waste within our team and daily operations. Turning waste boxes into shredded void fill Instead of discarding used cardboard boxes, we shred them into protective void fill. This repurposes waste and reduces the need for virgin void-fill materials, supporting a circular approach to packaging. Switching to kraft eco tape We've replaced traditional plastic tape with kraft eco tape, which is: Recyclable Plastic-free Strong and reliable Digitising our records To minimise paper consumption, we've transitioned to fully digital record-keeping. This reduces unnecessary printing, saves storage space, and ensures we operate with a lighter environmental footprint. Doing our part — together Earth Day is more than a date on the calendar — it's a call to action. Whether you're a small business owner, a large organisation, or simply someone who wants to make mindful choices, adopting sustainable packaging is a simple yet impactful step.
