E / B / C flute · 32–44 ECT · custom dielines Browse box types →Booklets, postcards, business cards, stickers, flyers, and hang tags — everything that goes in or on the box.
Saddle stitch · die-cut · roll or sheet Browse print goods →Ordering packaging for the first time comes with jargon. Here's the short version of the three questions every first-time box buyer asks.
Corrugated is the wavy-layered board used for shipping — strong, crush-resistant, protective. Paperboard is the thin, smooth stock used for retail cartons like a cereal box.
Rule of thumb: if it goes through the mail alone, corrugated. If it sits on a shelf or inside another box, paperboard.
The "flute" is the wavy layer inside corrugated board. E-flute is thin and prints crisply — ideal for mailers. B and C flutes are thicker and tougher — better for shippers carrying weight.
ECT (edge crush test) is the strength rating. 32 ECT covers most e-commerce parcels.
Box sizes are internal dimensions, listed length × width × depth. Measure your product, then add roughly a quarter inch of clearance per side — more if you're adding inserts or void fill.
Oversizing is the most common first-order mistake: it costs more and ships worse.
One price that includes plates, dies, and shipping — plus a cheaper alternative if one exists. Replies within 1 business day.
