Types of mailers for ecommerce and subscription brands fall into four families: corrugated mailer boxes, poly mailers, bubble mailers, and barrier film bags (including customizable mylar bags). The right choice depends on product fragility, weight, branding goals, and ship cost — not habit alone. BoxYourBrand produces end-to-end custom packaging for ecommerce and retail brands.
Shoppers often search bubble mail or mailer bubble when they mean cushioned film mailers. Personalized bubble mailers, small bubble mailers, and bubble pack envelopes cover jewelry, accessories, and soft goods; apparel brands lean on poly mailers clothing programs with logo print. Seasonal christmas mailers and professional mailers for PR kits use the same constructions with campaign artwork. Related formats include corrugated shipping boxes.
Key takeaways
- Corrugated mailer boxes win for branded unboxing and subscriptions; poly mailers win for lightweight apparel.
- Bubble mailers cushion small fragile goods; mylar/barrier bags suit coffee, freeze-dried food, and collectibles.
- Right-size every format — oversized outers inflate dimensional weight on FedEx, UPS, and USPS.
- Launch MOQs often start at 50 units for mailers and 500+ for poly film programs.
This guide compares types of mailer formats, covers common sizes like 10 x 13 poly mailers, and explains specialty options from blue mailer box branding to mylar bags for freeze dried food. For MOQ and ordering paths, see where to order custom mailer boxes and the mailer box size guide.

Corrugated mailer boxes
Corrugated mailers are self-locking boxes engineered for the unboxing moment. They protect better than film, accept interior messaging, and photograph well for social sharing. Use the quote wizard to compare quantity tiers side by side.
Blue mailer box programs use colored board or full CMYK exterior print to create instant brand recognition on the porch. Any Pantone or hex color is achievable on custom mailer boxes with logo — blue is simply a popular DTC choice.
Design subscription boxes build on mailer construction with:
- Fixed outer dimensions month to month
- Custom inserts and dividers for curated SKU layouts
- Interior lid print for onboarding and retention messaging
See subscription box packaging guide and subscription box packaging for format pairings and seasonal artwork workflows.
Poly mailers and common sizes
Poly mailers are the most cost-efficient ship format for non-fragile, lightweight products. Standard stock sizes include 7×10“, 9×12“, 10 x 13 poly mailers, and 14×19“ — each tuned to product thickness and carrier rate tiers.
| Size | Typical product fit |
|---|---|
| 7“ × 10“ | Socks, small accessories, samples |
| 9“ × 12“ | T-shirts, flat goods |
| 10“ × 13“ | Hoodies (folded), books, multi-item |
| 14“ × 19“ | Large apparel, bulk soft goods |
Custom printed poly mailers add logo, return address panels, and tamper-evident seals. Compostable and recycled film options support sustainability claims when certified.
Mylar bags and barrier film mailers
Customizable mylar bags use metallized or high-barrier laminates to block moisture and oxygen — critical for coffee, jerky, freeze-dried meals, and sensitive supplements.
| Use case | Why mylar |
|---|---|
| Freeze-dried food | Extended shelf life, moisture barrier |
| Coffee / tea | Aroma and freshness retention |
| Comics & collectibles | Protection from humidity and handling |
| Supplements | Light and oxygen sensitivity |
Mylar bags comics collectors use are often paired with rigid backing boards — a mylar bag with box shipper combination protects edges in transit. For food programs, confirm food-grade film and ink compliance when quoting mylar bags for freeze dried food.
Film mailers differ from corrugated mailers: lower unit cost and weight, less crush protection, no rigid structure for heavy items.
How to choose a mailer type
- Fragility — Fragile items need corrugated or bubble; soft goods ship in poly.
- Branding priority — Interior print and rigid unboxing favor corrugated mailers.
- Weight and DIM — Film mailers minimize dimensional weight on light parcels.
- Barrier needs — Oxygen-sensitive products need mylar or high-barrier pouches, not plain poly.
- Volume — Poly breaks favor 1,000+ units; corrugated mailers often start at 50 units.
