Common questions
Do these mailers require additional stiffeners or tape?
No. Stayflats Plus mailers are engineered with.020 chipboard that provides inherent rigidity. The integrated peel-and-seal closure eliminates the need for supplemental reinforcement or tape, saving time and material costs.
How durable is the self-seal closure for high-volume shipping?
The peel-and-seal closure is engineered for consistent, reliable sealing across thousands of mailers. The adhesive activates with gentle pressure and creates a tamper-evident seal that holds securely throughout transit.
What's the difference between Stayflats Plus and standard mailers?
Stayflats Plus combines puncture-resistant chipboard with an easy-open tear strip, eliminating assembly steps and ensuring professional presentation. The peel-and-seal mechanism is faster and more reliable than tape, reducing labor and improving consistency.
Are these mailers suitable for moisture-sensitive items?
While chipboard provides basic protection, these mailers are not waterproof. For moisture-sensitive contents, consider adding an interior protective layer or upgrading to a poly-lined mailer option.
