Businesses and individuals alike trust ePackaging Direct – a leading UK-based supplier of shipping supplies – for high-quality packaging. Our 6″×9″ (153×229mm) Grey Mailing Bags come in a convenient 200-bag bulk pack, perfect for mailing small items like clothes, documents, electronics and more. These grey poly mailers are made from thick 60μm polyethylene film, making them waterproof and extremely durable. Each bag features a strong peel-and-seal adhesive strip, so they close securely without tape. The opaque grey colour hides contents for privacy and looks professional during transit. With fast UK delivery and bulk pricing, you can easily buy these mailing bags online for your business or personal shipping needs.

Product Features

• Size: 6″ × 9″ (approx 153×229mm) – ideal for small parcels, books, paperwork, accessories and textiles. (Fits within Royal Mail’s large-letter dimensions for cost-effective postage.)

• Self-Seal Closure: Permanent peel-and-seal adhesive strip (approx 40 mm wide). Simply peel off the backing and press the flap to seal. No taping required, and once closed the seal is tamper-evident – “very hard to open” after sealing.

• Material: Heavy-duty 60μm opaque polyethylene (LDPE) film. It’s lightweight yet tear-resistant and puncture-proof. The plastic is water- and dirt-resistant, so mail stays dry and intact. (In fact, UK industry sources note these mailers are made from strong recycled polythene and are 100% recyclable.)

• Pack Quantity: 200 grey mailing bags per box. Economical bulk packs make it cheap per bag (for example, a 400-bag (2×200) order is just £3.98 ex VAT, under 2p per bag). Volume discounts apply – larger multi-packs (400, 600, 800 bags) give even lower unit cost.

• Colour & Opacity: Opaque grey ensures contents aren’t visible from outside (unlike clear bags), providing privacy for mailings. Also available in white, clear and other colours for different needs.

• Versatile Use: Perfect as small postage bags for eCommerce and mail orders. Great for shipping clothing, jewellery, cosmetics, DVDs, paperwork, gifts and any non-fragile items. Can also be used for storage or courier/shipping needs.

• Lightweight & Space-Saving: These poly mailers are extremely lightweight, helping reduce postage costs. They can be folded flat when not in use for easy storage. Despite being light, they are sturdy – industry peers confirm they are “tear and water resistant”.

Benefits

• Secure & Professional Packaging: The self-seal strip locks shut tightly, so items arrive intact and tamper-free. As one customer notes, these bags “seal securely and arrived fast” with “great customer service” (★★★★☆ Claire H.). The grey colour gives a sleek, professional look.

• Time and Cost Savings: No need for tape – simply peel and fold. This speeds up packing and saves on adhesive. Buying in bulk also saves money: the cost per bag drops to just a couple of pence with larger orders. You can mix and match quantities without a minimum order, so businesses can buy exactly what they need.

• Durable Protection: Made of tough plastic, the bags resist tears and moisture. They’ll protect items from rain, dust and rough handling. The material is durable enough that a UK supplier describes their mailing sacks as “strong recycled polythene”.

• Eco-Conscious Choice: These bags are made from recyclable polyethylene. When clean (labels removed), they can be recycled with other plastic films. Using lightweight poly mailers instead of boxes reduces material waste and carbon footprint. (For example, Packaging Products Online highlights that “all our mailing bags are 100% recyclable”, reflecting industry standards.)

• Wide Applications: Suitable for both B2B and B2C shipping. Online sellers on eBay, Etsy or Amazon use them for order fulfillment. Small businesses, craft shops, and home sellers find them ideal for sending out parcels. Even individuals use them for gift-giving, returns, or organising household items.

• Flexible Ordering: We offer a variety of options. Start with a 200-bag pack or choose larger multi-packs. For even more flexibility, see our mixed-size assortment: a 125-bag pack containing 25 bags each of five popular sizes. This “mix and match” pack is perfect for businesses needing multiple sizes.

Material Quality

Our 6×9 mailing bags are crafted from high-quality polyethylene (PE), a durable plastic widely used for packaging. Specifically, we use a 60-micron thick film (about 0.06 mm) – thick enough to resist punctures and tears, yet light enough to keep postage costs low. Industry sources note that poly mailers like these are made from “polyethene, a type of plastic renowned for its durability, flexibility, and resistance to moisture”. The opacity comes from grey pigment added to the plastic. This material is typically LDPE (Low-Density Polyethylene), which is recyclable.

These bags are BPA-free and contain no toxic coatings. They are certified safe for general use, and meet UK packaging standards. The strong 60μm construction ensures that even sharp-cornered items won’t easily poke through. Our mailers have been described as “heavy duty” and “tear-resistant” by satisfied customers, so you can trust them to keep goods safe. The self-seal adhesive strip is pressure-sensitive (with a 40 mm wide flap) and uses solvent-free glue, making it reliable yet non-toxic.

In summary, the material quality of our 6×9 grey bags means you get a sturdy, waterproof, and professional mailing solution. They shield contents from rain or moisture (the poly film is inherently waterproof) and guard against tampering. Despite the strength, the plastic remains flexible and lightweight – it bends without cracking and won’t crush like cardboard.

Use Cases

These 6×9 grey mailing bags are incredibly versatile. Common uses include:

• Apparel & Textiles: Perfect for shipping small clothing items (T-shirts, scarves, socks), accessories (hats, gloves), or fabric samples. The waterproof plastic keeps garments dry during transit.

• Printed Materials: Great for books, magazines, pamphlets, photographs, and documents. The opaque cover provides privacy for personal letters or sensitive paperwork.

• E-commerce Orders: Widely used by online retailers and marketplaces. Ideal for packaging small products like phone accessories, cosmetics, jewellery, pet supplies, and handmade goods. Their size and weight fit within Royal Mail’s Large Letter category, helping lower postage costs.

• Invoices and Catalogues: Small businesses often use them to mail invoices, product catalogs or promotional flyers. The sleek grey envelope looks professional, and the self-seal flap means faster packing.

• Gifts and Subscription Boxes: Use them to send gift items, craft kits or subscription box components. They provide a simple, branded packaging solution for small gift boxes or bundles.

• Storage & Organisation: Beyond shipping, they serve as handy storage bags. For example, retailers might reuse clean bags to sort small parts or promotional materials in the shop or warehouse.

These bags shine in any scenario where you need a quick, reliable way to send small items. Their peel-and-seal design makes packing up orders very efficient. Plus, because they are dust-proof and tear-resistant, customers receive merchandise intact, boosting satisfaction.

Environmental Impact

At ePackaging Direct, we’re mindful of sustainability. Our grey mailing bags are made from polyethylene (PE), which is a recyclable plastic. Industry experts note that “grey plastic mailing bags… are generally made from polyethene, a type of plastic… [that] can be repurposed into new products”. In practice, these bags can be recycled with other LDPE plastics if they are clean and free of labels/stickers. (Always check local guidelines for plastic bag recycling.)

Moreover, we utilize recycled content in manufacturing – as one supplier explains, their mailing bags are constructed from “strong recycled polythene”. While the bag’s strength comes from this robust material, it’s also designed to reduce waste. For example, compared to bulky boxes, poly mailers use less material and take up less space, cutting carbon emissions in shipping. After use, customers are encouraged to reuse the bag if possible or recycle it – this small act helps cut down on packaging waste overall.

In summary, these grey mailers are an eco-friendlier choice among plastic packaging options. They avoid excess bulk and are part of the UK recycling stream for plastic films. (If compostable or paper alternatives are required, please see our Eco-Friendly Mailing Bags category.) By choosing these bags, businesses can balance practicality with recyclability – helping meet sustainability goals in shipping.

Frequently Asked Questions (FAQ)

Q1: What are the dimensions of a 6×9 grey mailing bag?
A: They measure 6″×9″ (approximately 153×229mm). This makes them ideal for items up to A5 size or slim large-letter parcels. The exact metric size (153×229mm) is confirmed in our product details.

Q2: How do I seal these mailing bags?
A: Each bag has a permanent peel-and-seal adhesive strip under the flap. To close, just peel off the protective layer and press the flap firmly onto the bag body. The seal is strong and tamper-evident – once closed, it’s “very hard to open” without obvious damage. There’s no need for extra tape or glue.

Q3: Are these grey mailing bags waterproof?
A: Yes. They are made of thick polyethylene, so the bags themselves are water-resistant (However, labels and tape on the outside should be waterproof if the bag might get wet.) This means that rain or splashes during shipping won’t soak through to your products.

Q4: What are these mailing bags made of, and how strong are they?
A: They’re constructed from high-quality LDPE (low-density polyethylene) at 60μm thickness. This material is known for its toughness and flexibility. As one UK packaging provider notes, such mailing bags are “made from strong recycled polythene” that is both durable and tear-resistant. In practice, they hold up well under normal handling and protect contents effectively.

Q5: Can I recycle these grey poly mailing bags?
A: Yes. Being polyethylene-based, they are generally recyclable with other plastic films. After use, just remove any tape or labels and ensure the bag is clean and dry. Then you can recycle it at a plastic bag recycling point or facility. (Local guidelines vary, so check with your municipal recycling program.) In the UK, many grocery stores and recycling centers accept clean plastic mailers.

Q6: Can these bags be reused?
A: They’re designed primarily as disposable mailers, but because they’re sturdy, you can reuse them a few times if the bag remains intact. We often encourage businesses to reuse bags for second shipments or returns when possible. Once they wear out, please recycle them properly.

Q7: Will these bags qualify for Royal Mail Large Letter postage?
A: Yes, a 6×9″ (153×229mm) mailer fits within Royal Mail’s Large Letter size limits and weight limits (up to 25mm thick). Using them can help you keep postage costs down. ePackaging Direct’s own range is specifically designed to “fit within the Royal Mail PiP sizing to minimise postage costs”. For heavier items or thicker parcels, the Large Letter option provides savings over parcel rates.

Q8: Can I write on the grey mailing bags or apply postage labels directly?
A: Absolutely. The grey poly surface can be written on with a ballpoint pen or marker, and it takes sticky labels or stamps well. UK Packaging (a similar supplier) confirms that such mailing sacks “can be written on, and accept adhesive labels and stamps”. For best results, use a dark ink or white label on the grey surface.

Q9: How many bags come in the pack, and can I order more if needed?
A: This product is sold as a 200-bag pack (1 pack of 200). You can order multiple packs at once for more quantity. We also offer larger bulk packs – for example, two packs (400 bags) cost £3.98 ex VAT, three packs (600 bags) for £5.97, etc. Pricing is stepped so the more you buy, the cheaper per-bag. Check the related product links for 400, 600, 800 bag options or enter your required quantity in the shopping cart.

Q10: Do you offer smaller or mixed-size quantities?
A: Yes. While the smallest grey pack is 200 bags, we also have a 125-bag assorted pack featuring five different sizes (including 6×9). This mix-and-match pack gives 25 bags of each size from extra small up to large, which is great if you need variety or smaller quantities. Otherwise, you can order just one 200-pack or combine them for bulk.

Q11: What can I ship in a 6×9 mailing bag?
A: These mailers are great for lightweight, non-fragile items. Think clothing (T-shirts, scarves, socks), small electronics/accessories (phone cases, cables, earphones), books and magazines, jewelry, cosmetics, stationery and documents. They’re also useful for mailing hardware items (screws, fittings) or samples. Basically, any item that isn’t sharp or breakable can go in a 6×9 bag. For extra protection of delicate items, you might add tissue paper or bubble wrap inside.

Q12: How much do the 200-pack mailing bags cost?
A: As of today’s pricing, a single 200-bag pack is just £1.99 ex VAT (that’s only £2.38 inc VAT, about 0.9p each with VAT). Buying larger quantities reduces the per-bag price even more – for example, 400 bags cost £3.98 ex VAT (~0.9p each). We update prices regularly, so see the product page for the current price. Volume discount pricing is automatically applied when you increase the quantity.

Q13: How quickly will I receive my order of mailing bags?
A: We offer fast UK delivery. Order by 4 pm on weekdays and we’ll ship your order the same day. Most customers receive their delivery the next business day. (Rural or remote addresses may take an extra day.) We keep you updated with tracking info so you can plan shipments. If you need an urgent order, next-day delivery is available via our checkout upgrades.

Q14: Why should I buy these mailing bags from ePackaging Direct?
A: ePackaging Direct is a trusted UK packaging specialist (over 5 million orders served). We offer no minimum order, bulk discounts, and a huge range of related products (tapes, padded mailers, boxes). Our customer service is UK-based and knowledgeable. Plus, we stand by our products’ quality – these mailers are factory-direct and fully BPA-free. In short, you get great value, reliable stock, and fast service from a leader in UK shipping supplies.

Q15: Are discounts available for larger orders of mailing bags?
A: Yes. We use tiered pricing so bulk buys are cheaper per unit. As you increase pack counts, the price per bag falls. For instance, 400 bags (two 200-packs) cost £3.98 ex VAT (much less than 2×£7.96). Larger packs (600, 800 etc.) offer even deeper savings. The site automatically applies the best available discount for your quantity.

Q16: Can I use these mailing bags for international shipping?
A: Absolutely. Poly mailers like these are widely accepted worldwide. They meet international postal standards for small parcels. Just be sure to follow any specific country’s rules for labelling and customs documents. Their waterproof and tough nature makes them especially handy for global shipments, and the grey color gives your packages a professional look everywhere.

Q17: Is the grey plastic material BPA-free and eco-friendly?
A: Yes. These bags are made from PE that contains no added BPA or other harmful chemicals. They are BPA-free and safe for general use. Environmentally, as noted above, they are recyclable. Using recycled-content plastic and offering full recyclability makes them an eco-friendlier choice than many alternatives.

Q18: What is the advantage of grey mailing bags compared to clear or padded envelopes?
A: Grey mailers hide contents for security, whereas clear bags expose them. They are also much lighter and thinner than padded envelopes. This saves on postage and materials. Unlike padded bags, these are just the right size for small items and have no extra bulk. Compared to boxes, poly mailers like these cut down on material waste and shipping volume. In short, grey poly mailers offer privacy, waterproofing, and economy all in one.

Q19: How do I store and handle these mailing bags?
A: Store them flat in a dry place. They can be stacked or hung from the flap. Avoid extreme heat (as with any plastic, they could warp in very high temperatures). When packing, don’t overfill beyond their gusset. They’re flexible so you can fold the flap over neatly. After opening a pack, you can easily fold the remaining bags back into the box.

Q20: What if I have more questions or issues with my order?
A: Our UK support team is here to help. You can contact us via the website chat, email or phone for any inquiries. We offer a 30-day returns policy if you’re not completely satisfied (see our Returns page). We also have an FAQ section and a postage cost calculator on our site to assist with any concerns. We strive to make your purchase smooth and satisfying.
