Printed mailing bags are fast becoming a must have for any company or organisation that send out items or products to their customers. In particular for online ecommerce companies, these mailers (also known as poly mailers or plastic mailing envelopes) are a great way to get your brand or message noticed while safely protecting the contents inside. Each mailing bag features an adhesive strip on the reverse for easy and secure closure. They are also stronger (240g) than your normal standard carrier bag (180g) so they can withstand any wear and tear when being sent in the post. They are available in 4 popular sizes and every size is both tear and water resistant. The inside of the mailing bag is completely blacked out, so you can rest assured that anything that is put inside the mailing bag cannot be seen from the outside. All sizes of our custom mailing bags boast a very generous print area to ensure you get maximum impact for your budget. They give you a professional look while also attracting new customers.
