Will these protect rigid items from bending?

Are these mailers environmentally friendly?
Yes. These Stayflats Lite mailers are made from 100% recycled paperboard and are fully recyclable, supporting your brand's sustainability commitments and reducing carbon footprint per shipment.
What's the cost advantage for high-volume shippers?
The lightweight.018 chipboard reduces dimensional weight charges significantly compared to traditional rigid mailers, while the integrated self-seal closure eliminates tape expenses. For 1,000+ monthly shipments, savings typically reach 15-25% in combined shipping and packaging costs.
