Extra Large Grey Mailing Bags – 34x42" Heavy Duty Parcel Packaging
If you’re shipping oversized or bulky items, our 34x42 inch grey mailing bags provide a simple, reliable, and cost-effective solution. Designed for professional packers, retailers, and moving companies, these heavy-duty poly mailing bags ensure your parcels reach their destination clean, dry, and secure.
Built for Large and Bulky Shipments
These extra-large grey mailing bags are ideal for packaging larger goods such as bedding, textiles, clothing orders, soft furnishings, or multiple smaller items packed together. With a generous internal size of 864x1067mm, they offer plenty of space without compromising protection. The flexible design allows the bag to expand slightly while remaining tear-resistant and waterproof.
Durable, Weatherproof, and Secure
Each bag is made from tough 60-70 micron LDPE polythene that resists punctures, rips, and moisture exposure. The grey opaque finish keeps contents private, making these mailers perfect for eCommerce businesses that value both presentation and discretion.
The self-seal adhesive strip creates a tamper-evident closure — once sealed, the bag cannot be opened without visible damage. This ensures your customers receive their orders intact and professional-looking every time.

Why This Size Stands Out
The 34x42" option bridges the gap between standard mailing sizes and industrial packaging. It’s big enough for oversized soft goods yet flexible enough to fold down neatly when not in use. Businesses that send bulky or irregular-shaped items find this size ideal for keeping packaging efficient and professional-looking.
