Hi, everyone. Ricky Chu from Chu’s Packaging Supplies here. One thing about packaging that often gets overlooked is how much product you’re gonna fit in your box. You never want to overfill it or underfill it and I’ll show you why. Here I have a standard RSC box taped at the bottom, and I’m gonna fill it with our coveralls.

Let’s say we have an order for coveralls and I wanna ship this out. To maximize my profits, I wanna fill it as much as possible. Get it out in one shipment; save money on shipping. But the thing is, I’ll show you what happens when you overfill it.

Now, this box is over-filled. And you can see, because at the top, the flaps don’t meet. A lot of people like shipping like this I’ll show you what the problem is: the flaps don’t meet. So you’re gonna use extra tape. If you go down the middle, it’s probably gonna pop open just because the whole goal is to make the flaps meet at the top.

On the flip side, I’ll show you what happens when you underfill it. So this is underfilling, let’s say I have an order and I have two coveralls that I need to pack and I’m using the same box trying to save money on the shipping. When I fill it and close it, it looks good. Right? Flaps meet at the top. Well, the problem is you don’t get that resistance from the bottom.

Even though I taped it, I don’t get a good bite there. You see that. So that’s what happens when you underfill the box. Your best option is to fill your box properly and you will have less chances of your shipments popping open during transit. For more information about boxes and tips about shipping.
