Detailed Description

Grey Mailing Bags: Made in England for UK Sellers

At Cloud Packaging, we stock a wide range of polythene mailing bags — also known as postal bags, courier bags, or ecommerce mailers — in 18 different sizes to suit every parcel type. All our grey mailing bags are made in England to consistent quality standards, with next working day delivery across mainland UK and ultra-competitive pricing on every order.

Eco-Friendly and Built to Last

These grey mailing bags are manufactured from 99% recycled content and are fully 100% recyclable, making them a genuinely sustainable choice for UK ecommerce sellers. They’re produced to a strong 55mu–60mu thickness, giving excellent tear resistance so your parcels stay protected from despatch to doorstep. If you’re reviewing your packaging footprint more broadly, our guide to cutting packaging waste covers more ways to reduce material use.

Easy to Use, Opaque and Confidential

Each bag features a 40mm peel-&-seal strip, so parcels can be sealed quickly and securely without tape — ideal for busy dispatch operations. The opaque grey finish also keeps contents private and secure throughout transit, which matters for sellers shipping clothing or documents that customers expect to arrive discreetly packaged.

Trusted by Online Retailers and Fulfilment Centres

Grey mailing bags from Cloud Packaging are widely used by online retailers, eBay and Amazon sellers, fulfilment centres, marketing houses, and postal and courier companies. They’re a cost-effective, lightweight, and secure way to send clothing, documents, and other non-fragile items. If you’re sending garments specifically, our guide on what size box you need to send clothes can help you pick the right size, and we also stock pink mailing bags and blue mailing bags if you’d prefer a branded colour option.
