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.

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.

If you're customising your packaging, you can choose how thick you want the material.
