The Mailer-Specific E-Commerce Angle
Unlike our broader custom boxes line, this format is scoped for one job: getting a parcel through a shipping carrier’s network intact and on-brand. Crat Packaging builds every mailer around your product’s real weight and footprint, self-locking construction, and carrier dimensional-weight thresholds from the start.
Common Use Cases
- E-commerce brands shipping direct-to-consumer parcel orders nationwide.
- Subscription box companies needing a consistent, brandable monthly mailer.
- D2C brands across apparel, beauty, and consumer goods categories.
- 3PL and fulfillment centers standardizing on one mailer format across clients.
Material & Format Options
Self-locking mailers skip tape entirely for fast fulfillment-line assembly, tuck-top styles suit mid-weight products, and telescoping boxes handle bulkier or irregular shipments. Flute strength scales from E-flute for light goods to B-flute for heavier, crush-sensitive products.
Dimensional-Weight-Conscious Sizing
Because carrier dimensional weight charges are based on box size, not just product weight, we size every mailer tight to your product to help keep per-parcel shipping cost down.
Sustainable Packaging
A 2025 McKinsey & Company survey found over 60% of U.S. consumers pick green packaging when they have the choice. Crat Packaging offers recyclable and FSC-certified board options, soy-based inks, and minimal-waste die-cutting on every run, so brands can meet that demand without paying a premium or waiting on a specialty vendor.
Who Buys Best Custom Mailer Boxes Wholesale
- E-commerce and direct-to-consumer brands.
