When you need a reliable way to post or store large and bulky items, our 21.5x29.5" (550x750mm) grey mailing bags are an excellent choice. Designed for retailers, eCommerce businesses, and individuals who regularly send parcels, these mailing bags combine strength, protection, and affordability in one practical solution.
Made from high-quality, lightweight polythene, these jumbo grey mailing bags provide exceptional tear resistance and durability without adding extra postage weight. Whether you're shipping soft goods like bedding and apparel or more rigid items like shoe boxes and equipment, they ensure your parcels arrive clean, dry, and secure.
Strong, Waterproof, and Built for Tough Deliveries
Our grey mailing bags are made using premium-grade polythene that’s completely waterproof and puncture-resistant. The self-seal adhesive strip creates a firm closure that stays intact even during long-distance deliveries. This gives you confidence that your items are fully protected from moisture, dirt, and handling damage.
The large 550x750mm size offers generous space for oversized or multiple items in one shipment. It’s a great option for packaging larger textiles, cushions, electronics boxes, and even wholesale clothing orders. The opaque grey finish ensures privacy, keeping the contents discreet and professional-looking.
Ideal for eCommerce and Retail Businesses
Retailers and online sellers across the UK rely on strong, cost-effective packaging that represents their brand well while keeping goods secure. These jumbo grey mailing bags tick all the boxes — they’re lightweight to reduce postal costs, recyclable to meet sustainability goals, and tough enough to handle courier networks without tearing.
Whether you sell via Amazon, eBay, Etsy, or your own website, using professional-grade mailing bags can make a real difference in presentation and customer satisfaction. Their sleek grey colour projects a clean, modern look suitable for any business sector.
Practical Design and Easy to Use
Each mailing bag features a peel-and-seal closure that allows for quick, secure packing — no tape required. The smooth inner surface makes inserting products easy, while the thick outer layer prevents punctures and stretching. The grey colour also helps hide scuffs and marks during transit, ensuring parcels arrive looking tidy.
Eco-Friendly and Recyclable Packaging
