Introducing the Hemp Mailer 1.0 — Where Biopharma Meets Biobased
Naturally Insulated.
Clinically Aligned.
Engineered for Controlled Room Temperature (CRT) medications, specimens, and injectables, the Hemp Mailer 1.0 is a lightweight, ASTM-compliant thermal envelope designed for single-use or repeat last-mile cold-chain delivery. Built using natural hemp fibers and a moisture-resistant paper shell, it’s a sustainable alternative to petroleum-based mailers — without compromising thermal performance.ISTA-tested and certified for standard shipping lanes, our mailers protect your temperature-sensitive payloads with a low-carbon footprint and zero compromise on compliance.Maintains 2–8°C for standard transit durations.
Built for Biologics.
Powered by Plants.
We consistently match—and often outperform—petroleum-based foam and reflective bubble mailers.Our mailer is 89% bio-based hemp with a 100% recyclable kraft shell.
Meet HempWool™ — A Smarter Thermal Core for Biotech Shipments
HempWool is a natural fiber-based thermal liner for CRT and refrigerated pharmaceuticals, ideal for high-value biologics, dermatological injectables, hormone therapies, and research specimens.
