Frequently Asked Questions

Yes. The white outer surface is engineered for excellent ink and label adhesion. Stamps, handwritten text, and thermal shipping labels all adhere securely without slipping or peeling during transit.

The integrated tear strip provides a peel-and-seal closure that requires no additional tape, tape dispenser, or sealing equipment. Simply peel the strip, press for 3-5 seconds, and the mailer is permanently sealed, faster and more consistent than tape application.

The 2.5 mil polyethylene construction resists punctures, tears, and moisture penetration. High-strength seams prevent bursting under pressure. However, they are water-resistant rather than completely waterproof, suitable for most shipping conditions but not full water immersion scenarios.

The white exterior provides a professional, branded appearance ideal for customer-facing presentation, while the silver interior offers moisture barrier properties and opacity for light-sensitive contents. This dual-layer design maximizes both aesthetics and protection.
