These are #7 poly bubble mailers, 14 1/4 by 20 inches, sold in a 100-count pack. The white polyethylene outer film is laminated to a bubble cushion, so they resist moisture, punctures and tearing while staying light. A self-seal strip gives a tamper-evident closure, and a tear-open strip lets the recipient open the mailer without cutting into the contents. They suit sellers shipping larger soft goods, books, apparel or electronics accessories who want padded protection without a box. Against paper bubble mailers they are lighter and more water-resistant, but they are not rigid, so fragile items still need extra packing.

These poly bubble mailers are lightweight padded envelopes made from a multi-layer blend of polyethylene film. The film is moisture-resistant and durable. It is laminated to a cushioning bubble layer for added protection.
The mailer has puncture resistance, tear strength and cushioning performance. A patented tear opening system lets the recipient open it easily without compromising the mailer's integrity or the security of the contents.
The self-seal closure forms a tamper-evident seal to secure the contents. The outer surface is white.
