Mailing Bags For Clothes UK

Poly mailing bags for clothes (poly mailers) are lightweight plastic shipping envelopes made from low-density polyethylene (LDPE). They are widely used by UK clothing retailers and DTC brands as postal packaging for garments. These waterproof, tear-resistant self-seal bags protect apparel during transit without the bulk of boxes. Because LDPE is flexible yet strong, poly mailers resist punctures and keep items dry – ideal for shipping t-shirts, hoodies, dresses and more. In fact, a standard 55–60 micron grey poly mailer is strong enough for clothing yet thin enough to fit through most UK letterboxes. At ePackaging Direct, our Poly Mailing Bags for Clothes are designed specifically for fashion eCommerce: they come in UK-friendly sizes, include security seals, and ship fast across the UK.

Poly mailers are made of LDPE (low-density polyethylene) plastic – a durable, flexible material that is waterproof and tear-resistant. This makes them perfect for postal use: the strong plastic guards garments from moisture and damage. Most of our grey poly mailers use a 55–60 micron film (about 0.055–0.060 mm). For example, our 60µ grey mailing bags remain light yet tough, easily handling loads of clothes without bursting. Each bag includes a 40 mm wide peel-and-seal adhesive strip, so you simply peel back the liner and press shut – no extra tape needed. Once sealed, these strips are tamper-evident: they’re very difficult to open without visible damage, ensuring parcels stay secure. In practice, poly mailers offer better value for flat, non-fragile items than boxes. Their sleek profile reduces shipping weight and volume, often qualifying for lower UK postage rates. In fact, small to medium apparel like T-shirts, leggings or underwear often ship via large-letter rates in a 6×9″ or 9×12″ poly mailer. Larger mailers (up to 21×24″ or more) accommodate bulky clothing like jackets or multiple items.

Size and Thickness Options

Poly mailers come in a range of sizes to fit different garments. Common UK sizes start around 153×229 mm (6×9″) for small items, up to 600×900 mm (24×36″) or larger for bulkier items. We stock everything from extra-small to extra-large – for example, 6×9″, 9×12″, 12×15″, 15×17″, 17×24″ and beyond. Choosing the right size is key: a bag that’s too small won’t close, while an oversized bag wastes space (and shipping cost). A good rule is to measure your largest garment flat (length + 1–2 cm, width + 2–3 cm) to select a mailer that fits snugly. Because poly mailers lie flat, allow a small buffer for thickness (especially for coats or hoodies) to avoid over-stretching the bag.

Thickness (micron or gauge) also varies. Typical poly mailers range 35–65 micron. Thinner mailers (30–45 µm) are lighter and good for lightweight clothes; thicker mailers (55–65 µm) add durability for heavier or multiple items. All our mailing bags are water-resistant by design – rain won’t soak through the sealed plastic. For extra abrasion resistance, consider reinforced or bubble-lined poly mailers (our Padded Mailing Bags provide added protection). In summary, pick a mailer just large enough for your clothing, and a thickness that balances cost vs. strength. Our size guides and next-day despatch samples make it easy to find the right fit.

Self-Seal & Tamper-Evident Features

Every poly mailer in our UK range is self-sealing. That means each bag has a built-in adhesive strip: peel off the backing and press to close. This one-step closure speeds up packing and eliminates extra tape or glue. Once sealed, the bag’s wide adhesive provides a tamper-evident seal. In fact, our mailers are engineered so that any attempt to open the bag leaves visible damage – helping customers trust their order is intact. These bags are “extremely difficult to open, ensuring that your items arrive safely and without risk of opening or tampering”.

The strip is typically 40–45 mm wide, offering a strong bond to secure even bulky clothing. Many customers appreciate that a sealed poly mailer can’t be reclosed easily, giving added security for retail shipments. Because poly mailers are opaque (grey, white or coloured) they also provide privacy for customers (contents are not visible from the outside). For extra peace of mind, we also offer security-tape and void-label options if needed, but most retailers find the standard peel-&-seal suffices.

Eco-Friendly Poly Mailers For Clothes

For brands and stores with sustainability goals, we offer eco-conscious options within our poly mailer range. This includes biodegradable poly mailing bags, recycled polyethylene mailers, and other green alternatives.ePackaging Direct has “eco-friendly options are available, such as mailers made from recycled polyethylene or biodegradable and compostable materials”. In practice, this means you can ship clothes in mailers that will break down more quickly in landfill or that use post-consumer recycled plastic. For example, our eco mailers might be labeled “biodegradable” or “recyclable”. They maintain the same tear-resistant, waterproof properties but reduce environmental impact.

One popular choice is a biodegradable poly bag for clothes made from plant-based polymers. (Note: “biodegradable” doesn’t mean edible; it means the bag is certified to decompose under certain conditions.) For strictly organic packaging, we also carry compostable poly mailers. All these options meet UK waste regulations for compostable plastics. Using recycled poly mailers (made partly from returned plastic waste) is another easy switch – the bags feel and perform like regular LDPE but use recycled content, making them fully recyclable after use. These eco mailers are especially popular with eco-conscious fashion labels. (For more, see our Eco-Friendly Mailing Bags collection.) Regardless of material, all our poly mailers are dustproof and keep garments clean.

They arrive flat-packed to save warehouse space and are 100% recyclable where facilities exist. By choosing an eco poly mailer, UK sellers meet consumer demand for sustainable packaging without sacrificing durability or security.

Bulk Orders & Discounts (No MOQ)

Buying in bulk is where poly mailers truly shine. We offer wholesale pricing and volume discounts for poly mailing bags for clothes in uk – the more you buy, the lower the per-unit cost. For example, ordering a 200–500 pack of mailers can bring the price down to just a few pence per bag. (Indeed, a 500-pack of 6×9″ grey mailers works out to only about 1–2p each). Our website lists tiered pricing so you can see at a glance how cost drops with quantity. Best of all, at ePackaging Direct there is no minimum order quantity: whether you need 1 or 10,000 mailers, we can supply it.

We also provide fast UK delivery on all orders. Bulk orders come from our UK warehouse and can be dispatched next working day to most UK addresses. On larger orders (typically over £50–£100), we offer free delivery anywhere in the UK. All prices are shown exclusive of VAT, with VAT added at checkout. Our bulk mail packaging model is highly flexible – there are no hidden fees, and bulk discounts apply automatically. In short, stocking up on poly mailers reduces your shipping costs significantly. At ePackaging Direct, “we offer bulk discounts at competitive prices, plus next-day UK delivery”.

Suitable Clothing & Industry Use

Poly mailers are ideal for non-fragile, soft items. They’re perfect for items like T-shirts, underwear, swimwear, leggings, or other folded apparel. Even knitwear and lightweight sweaters ship well in poly mailers. For bulky items like thick coats or sneakers, a padded bag or box might be better, but many UK retailers still use oversized mailers (up to 21×24″) for jackets or shoe bags. The key is that the item should be flexible and not easily crushable.

UK fashion brands and DTC (direct-to-consumer) retailers love poly mailers for their branding opportunities and convenience. A sleek grey or coloured mailer can carry a custom logo or label (we offer custom printing on poly mailers too). Many clothing sellers choose neutral grey mailers for a premium look, while boutique brands might use a chic pastel or black mailer. The versatility means poly mailers are a “go-to” choice for eCommerce apparel – as one supplier notes, “our mailer bags are widely used as clothing mailer bags… lightweight, cost-effective, and professional”. They keep shipments light (saving on postage) and take up little storage space.

Whether you run a small Etsy fashion shop or a larger online store, our grey poly mailers for clothes and coloured poly mailers fit the bill. They meet requirements of UK couriers (Royal Mail, DPD, Hermes, etc.) for maximum parcel dimensions. Many are designed to fit the Royal Mail Large Letter category (up to 353×250×25mm) to save on postage. Poly mailers also comply with courier rules for “postal bags” (peel-off address window or clear label must display name/address). In practice, they integrate smoothly with UK shipping: just stick a printed address label on and drop in the post.

FAQs

Q: What sizes of poly mailing bags are best for clothing?
A: We carry a full size range. Small poly mailers (153×229mm, 6×9″) fit light garments and accessories. Medium sizes (229×305mm / 9×12″ or 305×381mm / 12×15″) fit most single clothing items like shirts. Large mailers (e.g. 381×508mm / 15×20″, 430×550mm / 17×22″) can handle bulkier items or multiple items. For reference, a folded hoodie usually needs at least a 15×20″ bag. If in doubt, measure your largest item and allow 2–5 cm extra in each direction. (Tip: poly mailers lie flat, so account for thickness.) Extra-large mailers (up to 21×24″ or more) are available for oversize orders or thick fabrics.

Q: Are poly mailers waterproof and tear-resistant?
A: Yes. Our poly mailing bags for clothes are naturally waterproof and made from tear-resistant LDPE. The plastic film keeps out rain and moisture. They are much more durable than paper bags: Our Mailing Bags for Clothes are “strong 55-60 micron LD-PE… waterproof, tear-resistant”. In testing, these mailers withstand rough handling in transit. (For extra security, the strong self-seal strips prevent accidental openings.)

Q: Do I need to tape or pad the mailers for clothes?
A: Generally no extra tape is needed – the built-in adhesive does the job. Padding isn’t required for typical clothing since they aren’t fragile. However, for delicate or sharp items (e.g. jewelry, shoes with heels), you could add tissue or bubble-wrap inside. For standard apparel, simply fold the item, insert it, and seal. The bag itself protects well from dust and spills, as endorsed by positive customer reviews (e.g. “Good seal so no need for additional tape. Decent thickness… protected from damage and inclement weather.”).

Q: Can I buy just a few mailers or get a bulk discount?
A: Yes – we offer full flexibility. You can order as few as one pack of poly mailers (no MOQ), or thousands at once. Bulk orders automatically receive volume discounts. For example, buying 10 packs will cost less per bag than 2 packs. We also often run promotions or bundle deals. Shipping is fast (UK next-day) even for small orders. For businesses stocking mailers, our bulk pricing makes each bag very affordable.

Q: Are your poly mailing bags for clothes eco-friendly?
A: We stock both standard LDPE mailers and eco-friendly variants. Options include recycled-content mailers, biodegradable poly bags, and compostable poly mailers. These green mailers perform like regular plastic bags (waterproof and secure) but meet environmental certifications. You can label orders “packaging recyclable” and let customers know you use sustainable materials. All eco options are in our dedicated Eco-Friendly Mailing Bags collection.
