Paper Mailing Bags
Paper mailing bags are the most practical plastic-free alternative to poly mailers for ecommerce despatch. Made from kraft paper, they're strong enough to protect non-fragile goods in transit, fully recyclable at home alongside standard paper recycling, and increasingly the first choice for brands moving away from polythene packaging.
Our range includes Priory Elements EcoMailing Bags, kraft paper mailers, and grass paper options — all plastic free, biodegradable, and available in a range of sizes for everyday despatch. For branded options, our custom paper mailing bags are available from 1,000 units.
What are paper mailing bags used for?
Paper mailing bags are best suited to non-fragile, pre-packaged goods — clothing, accessories, soft goods, books, and similar items that don't need a rigid box. The gusseted sides on our kraft paper mailers give them more volume than a flat envelope, making them a practical choice for bulkier soft items like folded garments.
Paper mailing bags for clothes in particular have seen significant uptake from fashion and apparel brands switching away from plastic polybags — they offer comparable protection for soft goods while being far easier for customers to recycle.
Priory Elements EcoMailing Bags
Our EcoMailing Bags are made from sustainably sourced materials, fully biodegradable, and printed with clear eco markers so your customers can see the credentials at a glance. 1% of every sale is donated to environmental charities worldwide through our partnership with 1% For The Planet — at no extra cost to you.
Royal Mail sizing for paper mailers
Paper mailing bags are well suited to hitting Royal Mail's large letter and small parcel size bands, which can significantly reduce per-item postage costs for lighter soft goods. Our Royal Mail size guide sets out the exact thresholds so you can match your bag size to the right band before you buy.
Frequently asked questions
Are paper mailing bags waterproof?
Our kraft paper mailing bags are splash-proof and water resistant, keeping contents protected from the elements between despatch and delivery.
Are paper mailing bags as strong as poly mailers?
Our paper mailers are made from single-layer kraft paper — they keep products clean, dry, and safe through the courier network for non-fragile goods. For items needing stronger tear resistance, our poly mailers remain the more robust option, though they require specialist LDPE4 recycling rather than home recycling.
Can paper mailing bags be recycled?
Yes — brown paper mailing bags and kraft mailers go straight into standard home paper recycling. Grass paper mailers are compostable too. Use our recycling locator to find your nearest facility.
