How to Close a Cardboard Box Without Tape

If you find yourself in a situation where you need to close a cardboard box but don’t have any tape available, worry not! There are several alternative methods you can use to secure your box without the need for tape. In this article, we will explore seven different techniques that can help you close your cardboard box effectively and securely.

How to Close a Cardboard Box Without Tape

1. Fold the flaps inward and seal them with string

This method is suitable for small or medium-sized boxes that are not too heavy. Start by folding the flaps inward, leaving some space between them. Then, use a string such as dental floss, twine, yarn, or fabric strips to tie the flaps together, securing them in place.

2. Place the flaps on top of one another but only fold them about three-quarters of the way over

For boxes with long overlapping flaps, you can use this technique. Fold one flap over another, leaving a small gap at the end. Then, tuck the last flap under the first one, creating an interlocking closure that can hold light or medium-weight items securely.

3. Use hot melt glue to seal off your cardboard boxes

When you need a more secure and durable closure, hot melt glue can come to the rescue. Apply a line of hot melt glue along the edge of the flaps and press them together firmly. Allow the glue to dry completely before moving or transporting the box.

4. Use staples to close the box

Staples provide a strong and reliable closure method, but this technique requires a stapler and some skill. Align and tighten the flaps, then staple them together along their edges. Ensure you choose the appropriate size and type of staples for your box.

5. Use a cardboard box latch

Cardboard box latches are convenient devices that can help you close a box without tape, glue, or staples. These metal clips attach to the flaps of the box, locking them together. Insert the latch into the slots on the flaps and press it down to secure it. You can easily purchase cardboard box latches online or at select hardware stores.

6. Use self-locking cardboard boxes

If you want a hassle-free solution, consider using self-locking cardboard boxes. These special boxes have built-in features such as tabs or slots on the flaps that interlock with each other when folded. They provide a secure closure without the need for tape or any other adhesive. However, keep in mind that self-locking boxes may not be available in all sizes or shapes.

7. Use strings to tie your box

This versatile method allows you to use any kind of string or rope you have on hand. Wrap the string around the box several times, ensuring it covers all the gaps between the flaps. Tie the string securely with a knot or a bow. For a more decorative look, you can even use ribbons or cords.


Closing a cardboard box without tape is indeed possible, thanks to these alternative methods. Depending on your box’s size, weight, and your available resources, you can choose the most suitable technique. Whether you opt for folding and sealing with string, interlocking the flaps, using hot melt glue or staples, employing a cardboard box latch, relying on self-locking boxes, or tying with strings, you can secure your box effectively and prepare it for storage or transportation.


Can I reuse the self-locking cardboard boxes?

Yes, self-locking cardboard boxes are designed for multiple uses. You can open and close them as needed without compromising their integrity.

Are there any weight limitations for the string-tied method?

The weight capacity of a string-tied box depends on the strength of the string or rope used. Ensure that the material you choose can support the weight of the box and its contents.

Can I use a regular glue gun for the hot melt glue method?

Yes, a regular glue gun can be used to apply hot melt glue. Make sure to follow the manufacturer’s instructions for safe and proper usage.

Where can I purchase cardboard box latches?

Cardboard box latches can be found online, specifically on e-commerce platforms or at selected hardware stores.

Can I combine different closure methods?

While it’s possible to combine closure methods, ensure that the combination you choose provides a secure and reliable closure without compromising the box’s structural integrity.
