The Complete Guide to Custom Bubble Mailers
Bubble mailers are the most-used padded envelope in ecommerce. They protect the product, ship light, and — when custom printed — turn every order into a branded touchpoint. This guide covers everything you need to know before ordering custom bubble mailers for your brand.
What are bubble mailers?
Bubble mailers are padded envelopes lined with a layer of bubble cushioning. The outer shell is usually co-extruded polyethylene (poly bubble mailers) or kraft paper (paper-padded). Both come with a peel-and-stick self-seal strip.
Bubble mailer sizes
Standard sizing runs from #000 (4 x 8 in) up to #7 (14.25 x 20 in). The most common ecommerce sizes are:
- #0 (6 x 10 in) — cosmetics, jewelry, small accessories (see our small bubble mailers)
- #2 (8.5 x 12 in) — t-shirts, soft goods, small electronics
- #4 (9.5 x 14.5 in) — folded apparel, hardcover books (see our large bubble mailers)
- #5 (10.5 x 16 in) — multi-item ecommerce orders (see our large bubble mailers)
Shop bubble mailers by size and style
- Small bubble mailers (#000–#1) — jewelry, cosmetics, accessories, AirPods
- Large bubble mailers (#4–#7) — hoodies, denim, blankets, bulky soft goods
- Clear bubble mailers — see-through padded envelopes for subscription kits and sample drops
Custom printing options
Custom bubble mailers are typically printed with full-bleed CMYK or spot Pantone colors across the entire outer surface. You can print one side, both sides, or wrap a design around the seal. Files should be supplied at 300 DPI with a 3mm bleed.
MOQs and pricing
Standard custom bubble mailer MOQ is 500 units. If you are testing branded packaging for the first time, see our low-MOQ option. Price per unit drops sharply at 1,000, 2,500, and 5,000+ runs.

Frequently Asked Questions
Can I ship custom bubble mailers with USPS, UPS, FedEx, and DHL?
Yes. Custom bubble mailers are accepted by USPS (First-Class Package, Priority Mail, Ground Advantage), UPS, FedEx, and DHL. As long as the printed surface does not obscure the shipping label or barcode, carriers treat them identically to blank mailers.
Are bubble mailers waterproof and tear-resistant?
Poly bubble mailers are water-resistant and puncture-resistant thanks to the co-extruded polyethylene outer shell and internal bubble cushioning. Kraft (paper-padded) versions are tear-resistant but not waterproof — choose poly if your route includes rain, snow, or humid climates.
Will custom bubble mailers trigger dimensional weight charges?
Most ecommerce bubble mailer sizes (#0–#5) ship under USPS First-Class or Ground Advantage based on actual weight, not dim weight. UPS and FedEx apply dim weight on packages over 1 cubic foot, which bubble mailers rarely exceed. Stay under 1 lb on USPS First-Class for the cheapest rates.
Can I ship custom bubble mailers internationally?
Yes. Bubble mailers ship internationally via USPS First-Class Package International, Priority Mail International, UPS Worldwide, FedEx International, and DHL Express. No special documentation is required for the packaging itself — only standard customs forms for the contents.
What sizes do custom bubble mailers come in?
Standard sizes run from #000 (4 x 8 in) through #7 (14.25 x 20 in). The most ordered ecommerce sizes are #0 (6 x 10), #2 (8.5 x 12), #4 (9.5 x 14.5), and #5 (10.5 x 16). Custom-cut dimensions outside the standard range are available on request.
What is the minimum order quantity per size?
Standard MOQ is 500 units per size. If you need multiple sizes, each size counts as its own MOQ run because each requires a separate print setup. Low-MOQ options starting at 250 units are available for first-time brands testing custom packaging.
Can I mix multiple sizes in one order?
Yes — you can split a single order across two or more sizes as long as each size meets its MOQ. Mixed-size orders ship together and use the same artwork, which keeps setup fees low while letting you cover small, medium, and large products in one production run.
What print methods are used for custom bubble mailers?
Two methods are standard. Flexographic printing is used for runs of 1,000+ units, supports up to 6 spot Pantone colors, and offers the lowest per-unit cost. Digital printing suits short runs and photographic full-color artwork — no printing plates, faster turnaround, but a higher per-unit cost.
Can I print full-bleed CMYK photography on a bubble mailer?
Yes, with digital printing. Flexo is limited to spot Pantone colors, so full-photo coverage is best produced digitally. Supply artwork at 300 DPI with a 3mm bleed on all sides for the cleanest result.
How long does production and shipping take?
Total turnaround is 2–3 weeks: 24–48 hours for a digital proof, 1–2 days for your approval, 7–14 days production, and 3–5 days shipping. Rush production is available on request and can compress the timeline to under 10 business days end-to-end.
Do you offer eco-friendly bubble mailers?
Yes. Recyclable poly mailers, recycled-content kraft bubble mailers, and curbside-recyclable paper-padded versions are all available. Water-based and soy inks can be specified on either substrate for a fully recyclable finished product.
