Cool Shield Bubble Mailers 18x22 Silver

These padded mailers measure 18 by 22 inches and come in a pack of 50. The silver exterior provides a clean, professional look for outbound shipments. They are designed for businesses and individuals who need reliable protective packaging for flat or moderately thick items.

Upgrade from basic poly bags or unpadded envelopes

When contents risk bending, scratching or minor impact, the internal bubble layer adds cushioning that simple mailers lack. The jump is worth it for documents, electronics accessories, books or small parts that need more than a thin plastic sleeve.

Limited by fixed 18x22 dimensions

Items larger than the envelope cannot fit, and bulky or heavy products may exceed the protection level of the bubble lining. The mailers are not resealable once opened, so they suit one-way shipping rather than returnable packaging.

  • Protects contents with padded bubble lining
  • Fits larger items at 18 by 22 inches

Questions about this item

What outer dimensions should I allow for the 18x22 mailers?

Each mailer measures 18 inches by 22 inches, so allow at least that footprint plus a small margin for the bubble lining.

How do I seal these Cool Shield mailers correctly?

Peel the protective strip to expose the self-seal adhesive, press firmly along the full flap length, and avoid trapping excess air inside the bubbles.

When should I replace a mailer instead of reusing it?

Replace any mailer that shows torn bubbles, a weakened adhesive strip, or punctures that could expose the contents during transit.
