See my priceFirst: “cardboard” means two different things
Paperboard is the single, smooth sheet used for retail cartons and tuck boxes, specified by weight or thickness (for example 350 gsm, about 18 pt). Corrugated board has a fluted middle layer between two liners and is what shipping and mailer boxes are made of, specified by flute: E-flute is about 1/16 in thick and suits printed mailer boxes, B-flute is about 1/8 in and suits heavier shipping boxes. Knowing which one you need tells you which kind of manufacturer to look for.
Where to look
- Online packaging stores with instant pricing. The fastest way to compare: choose a style, type your size and see a real price, often at minimums of 100 or less.
- Packaging trade shows and industry directories. Useful for very large or unusual projects where you want to meet the plant.
- Local corrugated plants. Often the best fit for very large runs of plain or simply printed shipping boxes.
- Referrals. Ask brands that ship products like yours who makes their boxes and how reorders have gone.
What to ask any box manufacturer
- Which board or flute, exactly? And is the size you gave the inside or the outside? Ours are inside dimensions.
- What is the minimum per design? Ours is 100 for printed boxes and 250 for rigid boxes.
- Is the price all-in? Tooling, printing and delivery in one number, or extras later? Ours include Free US shipping.
- What will I see before it prints? A dieline proof, a 3D proof, a physical sample?
- How long, from approval to my door? Production takes as few as 5 business days from artwork approval (up to 15), then delivery takes 25 to 35 days with Standard or 4 to 12 days with Expedited.
- What happens on a reorder? We keep artwork for 24 months and charge no setup fee to reorder.
