Poly Bubble Mailers

Buying bubble mailers in bulk? Poly bubble mailers are padded shipping envelopes with a white poly outside that's lightweight and water resistant, with a silver inside for privacy and a plastic poly bubble lining that cushions contents in transit. We carry every standard size from #000 (4" x 8") to #7 (14.25" x 20"), with a self-seal adhesive closure, sold by the case for wholesale and bulk buyers with volume pricing.

Poly Bubble Mailer Sizes

Which Size Bubble Mailer?

  • #000 to #0 (4" x 8" to 6.5" x 10"): jewelry, cosmetics, keys and small accessories
  • #1 to #4 (7.25" x 12" to 9.5" x 14.5"): books, phone cases, media and small electronics
  • #5 to #7 (10.5" x 16" to 14.25" x 20"): tablets, catalogs, folded apparel and larger fragile items

Choose a mailer about an inch larger than the item each way; for thick items, add the item's thickness to both the width and length.

Kraft vs. Poly Bubble Mailers

Poly bubble mailers are lighter and water resistant, with an opaque white and silver film for privacy. Kraft bubble mailers have a paper outside that takes labels and handwriting easily and has a classic look. Both have the same bubble cushioning and standard sizes. See our kraft bubble mailers.

Wholesale & Bulk Bubble Mailers

Every bubble mailer is sold by the case, 50 to 500 per case depending on size, with volume pricing on larger orders and free shipping on orders over $2,000. For ongoing or high-volume orders, request a quote.
