The Rigid Book Mailer & Variable-Capacity Envelope Folder (FEFCO 0401 / One-Piece Wrap Mailer) is the preferred flat-pack shipping packaging for hardcover books, vinyl LP records, art prints, catalogs, and flat electronics. Constructed as a cruciform (cross-shaped) blank, the product is placed in the center panel, the left and right wings fold inward over the edges, and the bottom and top panels wrap around and seal with a hot-melt peel-and-seal strip and an integrated perforated zipper tear-strip for frustration-free opening.

Total Flat Cruciform Width (W_blank)
W_blank = L_book + 2(H_depth) + 2(W_side_wing)

Sums the central book width, two vertical spine depth gussets, and two protective side wrap wings.

Total Flat Cruciform Height (H_blank)
H_blank = H_seal_flap + 2(W_book) + 2(H_depth)

Combines the top peel-and-seal tear-strip flap, front and back main panels, and top/bottom spine gussets.

Step-by-Step Export & Assembly Guide

  1. 1 Enter the Length (L), Width (W), and Spine Thickness/Height (H) of your book, album, or catalog.
  2. 2 Inspect the cross-shaped one-piece folder and perforated tear-strip lines on the 2D blueprint.
  3. 3 Export the 1:1 .DXF, .SVG, or .PDF file.
  4. 4 Place your book on the center panel, fold the left and right wings inward, wrap the bottom panel up, and fold the top peel-and-seal flap over to close.

Packaging & CNC Engineering FAQ

Frequently Asked Questions — Rigid Book Mailer Envelope

Why is a cross-shaped book mailer better than a standard padded bubble envelope?

Padded bubble mailers offer zero corner crush protection, resulting in dented book corners during postal sorting. A rigid corrugated wrap mailer suspends the book inside double-creased perimeter walls.

How does the tear-strip opening work?

Our generator adds two parallel perforated score lines (8mm apart) across the top seal flap so the customer can pull a zipper strip to open the package without using a box cutter that could slice the book inside.

Can I use this generator to make a 12-inch Vinyl LP Record Mailer?

Yes! Set Length = 325mm, Width = 325mm, Height = 12mm, and Thickness = 1.5mm (E-flute) or 2.8mm (B-flute) to create a standard 12-inch LP record cruciform mailer that holds 1 to 4 vinyl albums.

Where should the double-sided peel-and-seal adhesive tape be applied?

Apply a 12mm–15mm strip of hot-melt peel-and-seal transfer tape along the outer edge of the top closure flap, directly above the two parallel tear-strip perforation lines.
