PJ1 Poly Mailers measure 165mm x 240mm and are ideal for sending smaller items that can be folded flat to approximately A5 size such as scarves, gloves or lightweight t-shirts. Weighing just 5g, these are our smallest poly mailers providing great protection without adding to your postal charges. These poly mailers are made using premium quality grey 75 micron polythene with heat sealed edges and a high tack self-adhesive closure to create a secure, tamper-proof package. They're also made from 75% recycled material, making them a more environmentally option. Due to their composition, these bags are durable and robust, keeping their contents safe from water damage and making them resistant to puncturing or tearing in the post. The easy-open strip also gives the customer fast access to their purchases.
