STRUCTURE NOTES
About this construction.
Reading the code FEFCO 0212
The 02 series holds the slotted-type boxes: one-piece bodies die-cut from a single blank, joined with a glued, stitched or taped manufacturer's joint, and closed by flaps on the top and bottom. Slotted boxes ship flat and erect quickly, which is why this series carries most of the world's shipping cartons.
Within the series, 0212 identifies a specific published design. The four-digit code carries the full structural intent — only dimensions and board grade remain to be agreed.
Dimensions and board
The parameters above — internal length, width and depth, plus any construction-specific values this style needs — drive the whole blank: panel layout, flap depths and slot positions all derive from them, validated against the template's supported range. The 2D dieline and the 3D fold preview regenerate together from the same parametric structure.
A corrugated dieline is a starting point for production, not a substitute for converter judgment: flute profile, board grade and joint style all affect final dimensions and crush behavior. Confirm tolerances and material with your manufacturer before mass production — and erect the structure on screen first, so flap collisions and proportion problems surface before any tooling is ordered.
COMMON QUESTIONS
Quick answers about this template.
What is E-Commerce Mailer Box — Tuck Top, Slotted Base?
FEFCO 0212 is a corrugated design published in the FEFCO International Fibreboard Case Code; the four-digit code specifies the full construction, leaving only dimensions and board grade to agree.
Which dimensions does the E-Commerce Mailer Box — Tuck Top, Slotted Base dieline need?
4 parameters drive the blank: L (length), W (width), D (depth), Corrugated cardboard thickness (mm). Each value is validated against the template's supported range, and the whole dieline regenerates from them.
Can I see how E-Commerce Mailer Box — Tuck Top, Slotted Base folds before cutting it?
Yes. The interactive 3D fold preview and the 2D dieline are generated from the same parametric structure, so the fold you watch on screen is the geometry of the sheet you cut. Open the template in the preview studio to fold it at your own dimensions.
