What Are USPS Bubble Mailers and How Do They Work?

This dual-layer construction provides superior protection for lightweight, fragile items while maintaining the cost advantages of envelope-based shipping rather than box shipping.
The Bubble Wrap Envelope: Protecting Your Items During Shipping interior acts as a shock absorber, preventing items from shifting during transit and protecting against impacts from drops or rough handling. USPS offers several types of bubble mailers, each designed for specific shipping needs and weight requirements.
