In packaging, a brown box usually refers to a plain, unprinted corrugated cardboard carton in natural kraft color. It’s the standard box used for shipping, moving, and storage. Because it’s unbranded and neutral, it’s versatile for home moves, small-business orders, and general organization.

• Available in many sizes, from small cubes to large wardrobe-style boxes.
• Offered in different strengths (single-wall, heavy-duty, or bulk quantities).
• May list ratings like 23 ECT or 32 ECT that relate to stacking strength.

Choosing a brown box typically comes down to matching size and strength to your items, adding cushioning to limit movement, and sealing with packing tape for a clean, secure shipment.

In packaging slang, the term brown box describes generic, no-frills corrugated packaging used when protection and efficiency matter more than retail graphics. It’s common for online orders, wholesale shipments, and subscription kits.

• Plain exterior that’s easy to label or brand with stickers and tape.
• Neutral look that helps keep contents discreet during shipping.
• Pairs well with inserts, tissue, or custom touches inside the box.

If you want a more polished presentation without printing on the outside, consider customizing the unboxing experience inside while using a standard kraft carton for the exterior.

Most major carriers accept sturdy corrugated boxes in any color. Plain brown (kraft) is popular because it hides scuffs and takes labels well, but white or printed cartons can also work if they meet size, weight, and durability guidelines.

• Choose a box in good condition with intact corners and flaps.
• Match strength to the load; 32 ECT is common for everyday parcels.
• Remove or cover old barcodes and labels to prevent scan issues.
• Seal all seams with packing tape; reinforce the bottom for heavier items.

Policies can vary. For the most accurate requirements, review your carrier’s current packaging guidelines before shipping.

Start with your item’s measurements and the padding you plan to use.

1. Measure length, width, and height after the item is wrapped or boxed (if applicable).
2. Add 2–3 inches of space on all sides for cushioning.
3. Select a box whose inside dimensions fit that total.

Quick pointers:

• Small boxes: dense items like books, tools, or jars.
• Medium boxes: mixed household goods and electronics with padding.
• Large boxes: bulky, lighter items like bedding, pillows, or lampshades.

When in doubt, sizing up slightly can help with proper cushioning and easier sealing. Avoid overstuffing, which can stress seams and reduce protection during transit.

A multi-depth box is a corrugated carton with pre-scored height lines, so you can reduce its depth for a snugger fit. It’s useful when shipping items of varying heights without stocking multiple sizes.

1. Assemble the base and seal the bottom flaps with packing tape.
2. Place the padded item inside and find the score line just above the contents.
3. Carefully cut down the four corners to that score line using a safe cutting tool.
4. Fold along the score and seal the top flaps as usual.

Right-sizing the box can limit void space, reduce shifting in transit, and may decrease the amount of filler needed.
