A folded T-shirt or a pair of jeans slides into a 10 x 14 inch bag. You press the strip closed, and the parcel weighs little more than the garment. They also carry soft toys, pet beds and other items that can take a squash. A pack of 100 covers 100 orders. ## Bag size, film thickness and seal strip Match the bag size, in inches or millimetres, to your folded items. Ten by 14 inches, roughly 250 x 350 mm, takes one folded adult garment; a bulky hoodie or coat needs a 12 x 16 or 14 x 20 inch bag. Film thickness is usually given in microns. Thicker film resists tearing on conveyor belts and sharp corners. Look for 50 microns or more on clothing. The bag should be opaque so the contents stay hidden, with a permanent peel-and-seal strip that tears the bag if someone opens it. You can stick a thermal label on the matt grey outside or write on it in pen. Some packs include a second tear strip for returns, so check the listing if you accept them. ## Packing a clothing order Fold the garment to the bag size and slide it in. Add a sheet of tissue paper first if you want a neat reveal. Press the air out before you peel the strip and seal, so the bag sits flat and fits a slimmer postage format. Stick the label on the flattest part of the front, away from the seal flap. Weigh the sealed bag on your scale and measure its thickness before you choose a service, because a bag that bulges can tip from one size band to the next. Royal Mail publishes the current limits for each format. Keep the bags in an open box or a wall dispenser next to the folding area. ## Paper bags, padded envelopes or a box Recyclable paper mailing bags cost more per bag and go in kerbside paper recycling. Pick them if your shop promises low-plastic packaging or your buyers ask for it. Fragile, flat or valuable items need more structure than a bag offers. Use a padded envelope for small items that need cushioning, and a small single-wall box for boxed goods that would crush. ## 8p to 13p a bag At £8 to £13 for 100 bags, each bag costs about 8p to 13p. That low cost per order suits low-priced clothing where a few pence show up in the margin. Buy a larger size once you list coats and knitwear. A thick jumper forced into a 10 x 14 inch bag splits the seam in transit, and a torn bag can lose the item. ## Common mistakes - Keep a larger size for knitwear and coats; a bulky jumper splits the seam of a small bag. - Press the air out before you seal, so the parcel stays thin. - Labels across the seal flap lift. Stick yours on the flat front panel. - Post fragile items in a padded envelope or a box. - Choose thick opaque film: clear or thin bags show the contents and tear on belts. ## Guides - [Kids' clothes bundles and baby items not to resell](https://sellersetups.com/guides/baby-items-you-should-not-resell): How to build kids' clothes bundles that sell, and the baby items safety charities tell parents not to buy second-hand: car seats, cot mattresses and more. - [Best time to sell on Whatnot, Vinted and eBay](https://sellersetups.com/guides/best-time-to-sell): When toys, school uniform, festival clothes and Halloween stock sell, plus Whatnot show times, Vinted Bumps and eBay auction end times. - [Cheapest way to post a parcel in the UK](https://sellersetups.com/guides/cheapest-way-to-post-a-parcel): InPost lockers, Royal Mail and Evri compared on our checked prices: which service is cheapest for a flat item, a 2 kg parcel and a heavy box. - [How to sell on Vinted UK: first listing to sale](https://sellersetups.com/guides/how-to-sell-on-vinted-uk): A beginner's route through Vinted UK: fees, photos, your first listing, the 5 day posting deadline, getting paid and the HMRC reporting line. - [How to package clothes for Vinted](https://sellersetups.com/guides/package-clothes-vinted): Fold, wrap and bag a Vinted clothing sale so it arrives clean and uncreased, using a mailing bag sized to the garment rather than a reused box. - [How to post trainers without a box](https://sellersetups.com/guides/post-trainers-without-box): Lost the shoebox or bought the pair loose?

One folded adult T-shirt, shirt or pair of jeans. Bulky knits and coats need a larger bag. ### Are grey mailing bags waterproof? Poly film keeps rain off the contents, and the seal strip closes the opening. Seal it fully and keep the label off the flap. ### Can I reuse a mailing bag? With an intact seal strip, or a new one added, yes. A resealed old bag looks second-hand to buyers. ### Grey or paper mailing bags? Grey poly costs less per bag and resists rain. Paper bags suit shops that want plastic-free parcels and kerbside recycling. ### Do mailing bags count as a Large Letter? It depends on the sealed size, thickness and weight. Measure the packed bag against Royal Mail's current limits.
