Grey Mailing Bags

Our grey mailing bags are designed to be strong, durable, waterproof, and completely opaque—perfect for keeping your items secure during transit. Manufactured and imported using high-quality 50-micron (200-gauge) grey polythene, these mailers offer consistent strength and reliability. Each bag features a permanent self-seal adhesive strip, ensuring tamper-proof security once closed. Once sealed, the bags are difficult to open, helping to ensure your goods arrive intact and untampered.

Applications:

These grey mailing bags offer excellent value while protecting your items during shipping. The surface allows for easy writing and labelling, making them ideal for retail, mail order, and eCommerce businesses. Perfect for shipping clothing, shoes, gifts, and other soft or non-fragile items like T-shirts, scarves, and blankets. Their secure peel-and-seal closure makes them suitable for mailing everything from letters to small, medium, or extra-large parcels.
