The bubble-lined mailer, which comes in two colour options (white or gold), is a popular choice for most offices and packing stations. A number of sizes are available, and all adhere to the Royal Mail’s PIP guidelines. This, along with the lightweight materials used in the production of this envelope, potentially reduce shipping costs. All variations of the padded envelope have a peel and seal strip for ease of use and added security and are produced with a tear, burst and water-resistant, virtually indestructible polyethylene outer. This robust, secure, but light-weight mailer is suitable for the mailing out of a wide range of goods and has been responsibly sourced.
