12" x 16" (300mm x 400mm) Grey Mailing Bags

Give your products a professional finish befitting your organisation - invest in high quality mailing bags today.

Our durable mailing bags are designed to help vendors save time, manpower and money; they’re a lightweight alternative to conventional postal boxes which are especially suited to soft goods and apparel. Featuring a fully waterproof 60 Micron plastic membrane, these cost effective bags are guaranteed to help protect your items from superficial damage like rips and tears, moisture damage and much more.

Alternatively, use them with other packaging items such as bubble wrap for an additional waterproof layer and extra peace of mind. Owing to their hardwearing, moisture-resistant design, these versatile items can easily be delivering through smaller letter boxes, and are also safe to be left in designated spaces for collection.   

As standard, all of our mailing bags are fitted with self seal strips for added security, and can be used with adhesive labels or “Documents Enclosed” wallets. Remember to store in a slightly warm atmosphere for easier use with other adhesive products. Protecting your products doesn’t have to be expensive; invest in professional grey mailing bags today.
