A Practical Size for Everyday Shipping
The Metallic Bubble Mailers 6 × 9 (#0) is a popular choice for businesses that ship a variety of lightweight products. It offers more usable space than smaller bubble mailers without moving into larger envelope sizes, making it a practical option for day-to-day order fulfillment.
A metallic foil exterior helps resist moisture and everyday handling, while the 3/16″ bubble lining cushions products during transit. The pressure-sensitive self-sealing strip creates a secure closure in seconds, helping streamline packing for individual orders or high-volume shipments.
If your business regularly ships products that are too large for compact mailers but don’t require a shipping box, the 6″ × 9″ (#0) size is a dependable middle-ground solution.
