You’ll often see padded envelopes referred to as bubble mailers or padded mailers. On this page, you’ll find several styles:

• Kraft bubble mailers: Paper exterior with bubble cushioning inside.
• Poly bubble mailers: Plastic-style exterior that’s designed to handle moisture better than paper.
• Honeycomb padded mailers: Paper-based cushioning instead of bubbles.
• Expandable/gusseted mailers: Extra room for bulkier items.

Sizes vary (for example, 6 x 9, 7.25 x 12, 8.5 x 11, 10.5 x 15, 12.5 x 18), and many have convenient self-seal closures. Checking the product title and description can help you match the style and size to your shipping needs.

A quick measure and a little wiggle room usually does the trick:

1. Measure your item (length, width, and thickness) at the widest points.
2. Compare to interior dimensions in the listing, not just the outside size.
3. Add a bit of clearance (about 0.5–1 inch) so it slides in without straining the seal.
4. Match common sizes you see here (e.g., 6 x 9, 7.25 x 12, 8.5 x 11, 10.5 x 15, 12.5 x 18) to your item’s footprint.
5. Consider expandable mailers if the item is bulky or oddly shaped.

When in doubt, sizing up slightly can help avoid overstuffing, but oversized mailers may allow shifting. Reviewing product details on this page can guide the best fit.

Bubble mailers can work for small, less-delicate items when packed thoughtfully. Here’s a practical approach:

1. Pre-wrap the item with additional cushioning (e.g., bubble wrap or a protective sleeve) to reduce movement.
2. Choose a snug size so the item doesn’t slide around inside.
3. Protect edges and corners to minimize punctures from sharp parts.
4. Seal carefully using the self-seal strip; add tape if the contents are heavy.
5. Consider moisture resistance by selecting a poly exterior when exposure to the elements is a concern.

For very fragile or high-value items, a sturdy box with internal cushioning may offer more protection, depending on your needs and the item’s sensitivity.

Both protect with interior cushioning, but the exteriors differ:

• Kraft bubble mailers: Paper outside that’s easy to write on and looks classic. They’re commonly used for documents, photos, and lightweight items.
• Poly bubble mailers: Plastic-style outside that can help resist moisture and tearing. Product descriptions on this page note water-resistant or waterproof features on select options.

Other considerations include color/finish (white, kraft, metallic, or decorative), thickness, and closure style (self-seal, dual peel-and-seal, or zip tear). The best choice depends on handling conditions, presentation preferences, and how much durability or moisture resistance you want.

Most options here are self-sealing, so prep is quick:

1. Pack neatly so the item sits flat and doesn’t bulge excessively.
2. Peel the adhesive strip and press the flap firmly across the entire width for a secure hold.
3. Reinforce if needed with tape on the flap or corners when shipping heavier contents.
4. Label the flat side so barcodes and addresses are easy to scan/read; avoid placing labels over seams.
5. Use the right surface: kraft is great for writing; for poly or decorative finishes, use a strong label.

Some styles include dual peel-and-seal or tear strips for easier opening. Checking the product description helps you match the closure to your workflow.
