Custom Corrugated Mailers in Castle Rock, CO

Corrugated mailer boxes are the primary e-commerce shipping packaging format -- self-contained boxes that function as both the product's presentation packaging and the parcel shipping container, eliminating the need for a separate outer shipping box. Our corrugated mailers are produced from E-flute and B-flute corrugated board with premium exterior and interior printing options that transform the shipping container into a brand communication vehicle for the unboxing moment that every DTC shipment creates.

Mailer Box vs. RSC: The DTC Choice

The mailer box (also called a literature mailer or tuck-top box) uses self-locking tuck flaps at the top closure that create a tamper-evident seal without tape -- the interlocking flap geometry creates a closure that requires deliberate unfolding to open rather than simple lifting. This self-locking closure provides adequate tamper evidence for most e-commerce applications and creates a more deliberate, controlled opening experience than tape-sealed RSC boxes. For DTC brands investing in unboxing experience, the mailer box's self-locking closure is the superior format.

Interior Printing for Unboxing Impact

Interior printing on corrugated mailer boxes transforms the opening moment from product discovery to brand experience. The interior print surface -- typically 3-4 full panels exposed when the box is opened -- creates the visual context that frames the product's first impression. Bold interior colors, brand messaging, product photography, and playful copy all create the unboxing environment that subscription box brands use to communicate brand personality at the moment of maximum customer engagement.
