Our Priory Elements EcoMailingBags™ are the perfect packaging solution for sending a wide range of goods via royal mail. Measuring 190mm x 300mm x 25mm, these bags are perfectly sized to match Royal Mail large letter dimensions, making them a letterbox friendly packaging choice. Made from 140gsm kraft paper, these eco mailers are strong, robust and splash-proof, ensuring your goods are kept safe against the elements; whilst the peel and seal adhesive strip ensures a secure closure without the need for packing tape. Boasting a range of eco-credentials, our EcoMailingBags are recyclable, biodegradable, plastic free and made from sustainably sourced materials to ensure your despatch operation is as eco-friendly as possible. To help convey your eco message and highlight the importance of sustainable packaging, we have printed our EcoMailingBags with easy to understand eco-markers and assigned each bag an endangered animal, in this case, a Penguin. Not only do our animals act as a handy size guide, they also show our commitment – and yours – to protecting our planet and reducing our impact on the environment.
