Wholesale Mailing Bags UK – Bulk Mailers for Every Need

Looking for wholesale mailing bags in the UK? Our one-stop offers the largest range of poly mailing bags, padded mail bags, paper mailing bags, and grey mailing bags – all at unbeatable bulk prices. We carry poly mailing bags wholesale, polythene mailing bags wholesale, and even eco friendly mailing bags UK wholesale. Whether you need cheap mailing bags wholesale for economy shipping or custom mailing bags UK wholesale to promote your brand, we have the solution. Our mailing bags are lightweight yet durable; for example, our poly mailers feature a water-resistant layer for extra protection. And if you ship fragile items, our padded bubble mailers add cushioning inside the envelope. All styles come in multiple sizes (from small ~6.5″×9″ [16.5×23.0 cm] up to large 22″×30″ [56×76 cm]) and colors, including sleek grey for a professional look.

• Polythene & Poly Mailers: Lightweight plastic mailing bags (poly mailers) that are tear-resistant and waterproof. Perfect for clothing, documents, and items that need moisture protection.
• Padded Mail Bags (Bubble Mailers): Bubble-lined mailing bags offering extra shock-absorption. Ideal for electronics, jewellery, and fragile products.
• Paper Mailing Bags: Eco-friendly kraft mailers made from recyclable paper. These biodegrade naturally and appeal to sustainability-minded customers. In fact, roughly 69% of paper packaging is recycled in the UK, so our paper mailers greatly reduce waste.
• Grey Mailing Bags: A neutral, professional-looking poly bag (often made with recycled material). Grey mailing bags give “a very professional look” and accommodate postage labels easily. Many grey mailers use recycled plastic, making them an eco-friendly mailing bags option.
• Custom Printed Mailers: Have your logo or branding printed on any style of bag. Custom mail bags help you market with every shipment. We offer custom printing on bulk orders so your brand stands out on every parcel.

Our mailing bags cover courier packaging and ecommerce shipping needs alike. For example, marketing reports show that lightweight flexible mailers dominate the e-commerce segment for their space-saving and cost-saving benefits. Because our poly mailers are so light, you save on postage too. Yet they still provide reliable protection for “deliveries of all shapes and sizes”. Whether you’re mailing a book, a t-shirt, or multiple items together, our bags are sized to fit securely and seal quickly (no need for boxes or extra tape).

Sustainability & Eco-Friendly Packaging

Consumers care about the planet. In fact, a NielsenIQ study found 61% of UK shoppers say sustainability is more important now than two years ago. Globally, about 81% of consumers demand sustainable packaging. We respond by offering eco-friendly packaging alternatives throughout our mailing bag range. Choose our biodegradable and recycled materials to reduce waste. For context, the UK generates roughly 11 billion pieces of packaging waste each year – around 12 million tonnes of material including 2 million tonnes of plastic. By switching to recyclable poly mailers or compostable paper mailers, your business can lower its environmental footprint significantly. (BusinessWaste reports that ~69% of paper/cardboard packaging is recycled in the UK, whereas only 44% of plastic packaging is recycled, underscoring the benefit of our recyclable paper bags.) We even offer 100% recycled and biodegradable poly mailers, so your customers can feel good about reusing or recycling the packaging.

Our commitment to sustainable packaging also means reducing excess bulk. All our mailing bags are space-efficient and use minimal material without compromising strength. Shipping experts note that choosing the right posting bag size (just slightly larger than the item) minimizes waste and weight. For example, for a standard hoodie we recommend a 12″×16″ (30.5×40.6 cm) poly mailer, which gives enough room for padding but isn’t overly large. Paper mail bags can be recycled after use, and we offer reusable options for businesses shipping returnable goods.

Frequently Asked Questions

Q: What types of wholesale mailing bags do you offer?
A: We stock a wide variety: Poly mailers (plastic bags with peel-seal), padded mail bags (bubble-lined envelopes), paper mailers (kraft mailbags), and specialty bags like grey mailing bags (high-opacity poly). We even offer custom printed mailers with your logo. All styles are available in bulk.

Q: Are your mailing bags durable and water-resistant?
A: Yes. Our polythene/poly mailers are made of tough, tear-resistant material with a water-resistant outer layer. Grey mailing bags use thick plastic that resists punctures, and padded bags have tough outer layers. These features protect contents from moisture and damage during courier shipping.

Q: Can I recycle or compost these mailing bags?
A: Many of our bags are recyclable or compostable. Our paper mailing bags are fully recyclable and biodegradable. We offer biodegradable poly mailers (made from plant-based materials) that will naturally break down. Even standard polyethylene bags can be recycled through appropriate facilities (though only ~44% of UK plastic packaging is currently recycled, our suppliers use recycled material where possible). We encourage customers to reuse the bags or recycle them with other plastic films.

Q: Can I get custom printed mailing bags in wholesale quantities?
A: Absolutely. We specialise in custom mailing bags UK wholesale – add your logo or design to poly, padded, or paper mailers. Typically there are low run quantities for printing (e.g. 1,000+), and we work with you on artwork. Custom branding on mailers can be a cost-effective marketing tool.

Q: How do I choose the right size mailing bag?
A: Measure your product and pick a bag slightly larger for padding. For example, a t-shirt or hoodie often fits in a 12″×16″ (30×40 cm) mailer. A standard A4 document may go into a 10″×14″ (25×35 cm) envelope. As a rule, the bag should accommodate the item and any protective padding. One packaging guide advises to “determine the size and weight of your products, then choose a shipping bag size that accommodates them with some extra room”. Our size chart shows dimensions in both inches and centimetres to help.

Q: Which is better for delicate items – poly mailers or padded mailers?
A: While poly mailers are great for lightweight, non-fragile goods, padded mail bags (bubble mailers) are recommended for fragile items. The built-in bubble cushion absorbs shocks and guards contents from drops. So, for electronics, glass, or any breakables, choose padded mailers in an appropriate size.

Q: Why should I buy wholesale instead of retail?
A: Wholesale means a lower cost per bag. We sell in packs of 100 or more at significant discounts. Bulk buying also reduces shipping cost per unit. Combined with our Price Match Guarantee and bulk order discounts, you’ll pay far less per bag than buying small consumer packs. We tailor prices for business orders, not one-off shoppers.

Q: What are the benefits of grey mailing bags?
A: Grey mailing bags offer privacy (contents are not visible) and a professional look. Many grey mailers are made from recycled plastic, making them an eco-friendly choice. They still have the same durability as white or clear poly mailers but with a neutral, branded appearance.

Q: How quickly can I get my order?
A: We ship next-day on orders placed by 3pm (UK mainland). Most customers receive their mailing bags within 1–2 business days. We always keep best-selling sizes and types in stock due to high demand.

Q: What is a Price Match Guarantee?
A: If you find an identical mailing bag product (same material, size, and quantity) cheaper elsewhere, we’ll match that price. This guarantee, along with our already low rates, ensures you’re getting the lowest wholesale mailing bag price in the UK.
