Common questions
Do these mailers require tape or additional adhesives?
No. The pressure-sensitive self-seal closure activates with simple hand pressure, just peel the release strip, align, and press. This eliminates tape costs and speeds up fulfillment by 40% compared to traditional taped mailers.
Will these protect rigid items from bending?
Yes. The.018 chipboard construction is rigid and non-bendable, making these ideal for photographs, documents, and flat products that cannot tolerate creasing. They're specifically designed to prevent damage during USPS, UPS, and FedEx transit.
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.
