Eco-Friendly Options

We also stock paper mailing bags and mailing paper bags for brands focused on sustainability. These recyclable and biodegradable options offer the same performance and presentation—without the plastic.

General eCommerce Orders

For online retailers shipping a wide variety of products, poly mailing bags remain one of the most cost-effective, space-saving, and protective packaging solutions. Whether you're shipping tech accessories, health & beauty products, or handmade items, plastic mailing bags offer lightweight durability and reduce postage costs. These mailing bags are tamper-proof, waterproof, and come with peel-and-seal strips for fast, secure fulfilment perfect for growing eCommerce operations that need to move quickly and efficiently.

Clothing & Apparel

If you're shipping garments, you'll love our selection of mailing bags for clothes. Lightweight yet strong, our apparel shipping bags and grey mailing bags offer the perfect balance of cost-efficiency and style. Choose from sleek polymailers or branded plastic shipping bags to reflect your business identity while keeping postage costs low.



Sustainable Brands

If sustainability is a priority for your business, consider switching to paper mailing bags or mailing paper bags. These eco-friendly alternatives are made from recycled or FSC-certified paper and offer strong protection for lighter goods while being fully recyclable and biodegradable. Many of our eco mailing bags are also compostable, giving your customers a packaging experience that aligns with your brand values—without compromising performance or professionalism.

Books & Smaller Items

When it comes to shipping books, documents, small electronics, or accessories, lightweight plastic postage bags and smaller parcel bags offer the perfect solution. These compact bags are tough enough to withstand handling, yet thin and lightweight enough to minimise your shipping costs. Whether you're sending notebooks, DVDs, or mobile accessories, small postage bags help reduce excess packaging and improve the unboxing experience for your customers.



Bulky or Padded Products

Shipping products with irregular shapes or fragile contents? Our bubble wrap mailing envelopes and large parcel bags provide that extra layer of shock absorption and security. Lined with protective bubble wrap, these bags are ideal for cosmetics, electrical items, gifts, and other items prone to breakage. Choose padded mailing bags to ensure your goods arrive in perfect condition—especially for high-value or delicate orders that need more than just surface protection.

Extra-Large Orders

Need something bigger? Our extra large mailing bags and big postage bags are made for bulkier shipments. These heavy-duty plastic parcel bags are commonly used by wholesalers, fashion retailers, and fulfilment centres shipping jackets, multiple items, or boxed goods. With widths over 700mm and robust tear resistance, these extra large postage bags offer the size and strength needed for reliable shipping on a larger scale.
