The Natural-Born Shipping Box That Brands Love
Custom kraft mailer boxes built for e-commerce and DTC brands. Natural brown corrugated board, 100% recyclable, ships flat. Full-color exterior or minimalist 1-color flexo. From small jewelry mailers to large apparel boxes.
Kraft mailer boxes are the workhorse of e-commerce packaging. The natural brown corrugated board signals sustainability without a word of marketing copy, and the tab-lock closure assembles in 3 seconds without tape or glue. Built on E-flute corrugated board (1.5mm thickness), these mailers protect products through courier handling while keeping dimensional weight low. The kraft exterior accepts 1-color flexo printing (logo and social handles) or full-wrap CMYK for maximum brand impact. White ink on kraft creates a striking contrast that photographs beautifully for unboxing content. Every kraft mailer ships 100%% flat, stacking at 50+ boxes per inch of shelf space. Assembly takes 3 seconds: fold, tuck, done. No tape gun, no poly mailer, no void fill for snug-fit products. Starting at $0.45/unit for 500-piece orders. 100%% curbside recyclable. FSC-certified stock available.
Kraft mailer boxes dominate e-commerce packaging for a reason: they cost less than white mailers, signal eco-consciousness through their natural brown aesthetic, and deliver the same crush protection. Over 60%% of DTC brands launching in 2025-2026 chose kraft as their primary shipping format (Packaging Dive survey).
Cubit manufactures kraft mailers on E-flute corrugated board — 1.5mm thick with a smooth kraft liner on both sides. The E-flute provides excellent crush resistance (supports 15+ lbs stacking weight) while keeping the box profile thin enough for USPS flat-rate and courier-friendly dimensions.
The natural kraft surface is the star: it communicates sustainability, pairs with any brand color palette, and creates the rustic-premium aesthetic that DTC customers share on Instagram. Print options range from minimalist 1-color flexo (your logo in white or black) to full-wrap CMYK offset with interior printing for an elevated unboxing experience.
All Cubit kraft mailers use FSC-certified corrugated board made from 70-100%% recycled content. They are 100%% curbside recyclable, compostable, and biodegradable. No plastic lamination, no foam inserts — just paper and soy-based ink.
