Expandable paper mailer

Grounded's recycled paper mailers are made from FSC-certified recycled wood pulp and are both compostable and kerbside recyclable. The recycled paperboard provides a rigid structure that is both durable and waterproof, while the optional side gussets expand to provide greater volume for larger items.

    Frequently asked questions

    Different packaging materials and formats have unique considerations. The Customisation section shows the dimension allowances for each product and range of film thicknesses in microns (µ); these two specifications determine volume and weight limits.
    Recycled content is of more variable quality than virgin material. The recycled material creates a speckled, grainy texture but does not effect print or packaging quality.
    Yes they can. Grounded's recycled films and paperboard materials are recyclable. Recycled plastics are able to be recycled in either dedicated PE streams (#4) or via in-store collection systems such as Red Cycle. All recycled paper products are kerbside recyclable.
    Yes, our paper mailers and mailer boxes are made using recycled uncoated board and can be recycled in any paper waste stream.
    We have paper stock available starting from 80GSM right up to 400GSM. Key considerations when deciding which thickness to choose are the weight of your product, the rigidity of the mailer and your durability requirements. We've found a good balance of all of these in our range of mailers, made using 180GSM paper.
    If you require a waterproof mailer, you are best to choose either our compostable or recycled plastic mailers. Our paper mailers are water resistant and will withstand rain during transit but aren't designed to be left out in the wet.
    Our stock compostable and PCR recycled mailers are 60µ or 2.36mil. Our stock paper mailers are 180GSM. We've seen a lot of mailers in our time and have found these to be the most optimal thicknesses, striking a perfect balance between price, durability and sustainability. If you're customising your packaging, you can choose how thick you want the material.
    Yes, if your order for custom packaging meets the MOQ for your product we can customise the size and print. For minimum and maximum dimensions for each product, check the Customisation section on the product page for more information on sizing.
    Grounded has a range of different packaging formats available on our online store that are able to be purchased in smaller quantities. These have been designed for labels to be applied.
