These Priory Elements EcoMailers measure 250 x 150mm and are made using e flute corrugated cardboard, which is super lightweight and has a great crush resistance. The thin design is great for saving on storage space and reducing the outer box dimensions for optimising your postal costs. With pre-folded depth creases and a peel and seal closure, you can quickly and efficiently pack your products, great for saving you time. These corrugated cardboard mailers also feature a tear strip so that your customers can easily open your packing. Not only are these mailers designed for efficiency and ease of use, but they’re eco-friendly too. Made from sustainably sourced recycled materials, 100% recyclable, plastic-free, and biodegradable, you can be confident that you’re delivering your products in packaging that protects the planet. These Ecomailers are also assigned an endangered animal, the red squirrel, which helps raise awareness whilst also acting as a handy size guide. With each purchase of these Priory Elements EcoMailers, 1% of the sale is donated to environmental charities as part of our partnership with 1% For The Planet.
