Custom Flap Boxes

A flap box comes with a Swedish bottom that is easy to assemble and does not require tape to stay closed. The flap on top also makes it quick and simple to seal.

* Due to the production process for custom-made boxes, the delivered quantity may vary from your order by a maximum of 15% (up to 1,000 units) or a maximum of 10% (above 1,000 units). You only pay for the boxes actually delivered.

What is a flap box?

The flap box, also known as FEFCO 0215, is a box designed for quick assembly. Its name comes from the top flap used to close the box. It also features a Swedish bottom, consisting of four interlocking flaps. When setting up the box, the flaps slide into each other to form a solid base. This design means no tape is needed on the bottom.

How to close a Swedish bottom box

A Swedish bottom box is not an auto-lock box, but a press-lock box. You assemble it manually. Some boxes come with numbers on the flaps, showing the correct folding order. If not, follow these steps:

Open the box so it takes shape
Fold the large flap with the notch inward
Fold the two smaller flaps inward
Fold the last large flap with the tab over the others
Push everything firmly inward so the tab locks in place
Set the box upright and start filling

Frequently asked questions about flap boxes

What is the difference between a flap box and an auto-lock box?

A flap box (FEFCO 0215) closes at the bottom with a Swedish bottom, where four flaps interlock to form a sturdy base. An auto-lock box (FEFCO 0711) has a pre-glued bottom that pops into place automatically. Both are quick to assemble, but the auto-lock is even faster, making it ideal for high-volume use.

Can I use flap boxes for heavy products?

Yes, provided you choose double-wall cardboard. Single-wall is suitable for light to medium-weight products, while double-wall offers extra strength for heavier or fragile goods.

Do flap boxes always work without tape?

The bottom does not require tape to stay secure. However, for the top side, tape or a sealing strip is often used to close the box properly for shipping.

Can flap boxes be printed with my logo?

Yes, flap boxes can be printed: from a simple logo to a full design, depending on the board type and the desired look.

What is the minimum order quantity for flap boxes?

Flap boxes can be ordered from 250 pieces. For orders over 5,000, request a custom quote.
