Limeloop

LimeLoop makes reusable shipping mailers intended to replace single-use cardboard boxes and poly mailers for companies that ship physical goods. Brands pack orders in LimeLoop's durable mailers and ship through their existing carriers; the recipient unpacks the order, prepares the mailer for return, and drops it in any mailbox, after which it travels back to the sender to be packed and shipped again. The company states the mailers are built for at least 20 or more uses and that the return process requires no label printing or post office trip.

The offering is positioned around three claimed benefits: waste and emissions reduction (up to 85% fewer carbon emissions per shipment, with each mailer replacing multiple single-use boxes), a tactile unboxing experience for end customers, and cost amortization as per-shipment cost declines with repeated reuse. LimeLoop says its mailers work with all major carriers and fit into existing fulfillment workflows, with onboarding taking less than two weeks. It also addresses loss and damage, describing lost mailers as a minimal share of volume relative to overall savings.

Business model

LimeLoop supplies reusable packaging to brands that ship products, combining physical mailers with a return-by-mail loop so the same packaging is reused across many shipments rather than sold once as disposable packaging.

Traction

The company cites use by consumer brands, naming apparel company Toad & Co as a customer whose customers comment on the packaging, and lists media features in Good Morning America, Forbes, The New York Times, Fast Company and Outside Magazine.
