What subscription boxes packaging has to do.

  • 01Shipping durabilityE-flute corrugated is the common mailer board; B-flute is stiffer for heavier boxes. ISTA test procedures such as ISTA 3A simulate parcel shipping.
  • 02Dimensional weightCarriers bill by dimensional weight when a box is large for its weight. Sizing the box tight to the contents lowers postage; see our dim-weight calculator.
  • 03Inside printThe unboxing moment happens inside the lid. Printing the inside adds cost but is where subscription brands get their photos.
  • 04InsertsPaperboard or corrugated inserts stop products shifting and arrive looking arranged.
