Corn again
Yep, that’s right.
These babies look like plastic and feel a little like plastic, but they’re made from 100% biodegradable and compostable materials.
Specifically, they are made from corn starch, PLA (made from corn) and PBAT (Polybutyrate Adipate Terephthalate).
Just take the extra bits off and they will decay away, nourishing future generations of flora.
Food for worms
At the end of its journey—once your customer has received their wares—the mailer can simply be stripped of its label and tossed in with the food scraps.
From there, it will start breaking down. Within 90 days, in the usual course of home composting, your mailer is as good as dirt (rich nutrient-dense dirt).
These clever mailers have passed stringent certified home compostable requirements, which includes a worm toxicity test, so they’re even worm farm friendly.
Try them on for size
Perfect for shoving up to 1 lb of stuff into. Each one measures 9.5 in X 13 in when folded over and sealed.

Keep them like red wine
Because they’re made from plants not plastic, our Sendle mailers do have a shelf life of about 9 months in normal storage conditions. If you want them to age well please keep them in a cool, dark place—like a filing cabinet, office drawer, or cupboard.
