Hey there! I'm a supplier of mailer corrugated boxes, and today I wanna talk about something super important – the compression strength of these boxes.
First off, let's get into what compression strength actually means. In simple terms, it's the amount of pressure a corrugated box can handle before it starts to collapse or get damaged. You see, when you're shipping stuff, your boxes are gonna go through a lot. They'll be stacked on top of each other in warehouses, jostled around in trucks, and maybe even get piled up in delivery vans. So, having good compression strength is crucial to make sure your products inside the box stay safe and sound.
Now, there are a few factors that can affect the compression strength of a mailer corrugated box. The first one is the type of corrugation. There are different flute sizes, like A, B, C, E, and F. Each flute size has its own characteristics. For example, A flutes are pretty thick and offer good cushioning, while E flutes are thinner and are great for printing and a more rigid look. Generally, thicker flutes tend to have higher compression strength, but it also depends on how they're used and the overall box design.
The quality of the paper used in the box also plays a huge role. Higher - grade papers with better fiber content are going to be stronger. The linerboard, which is the flat part of the corrugated board, and the medium, which is the wavy part, both need to be of good quality. If the paper is weak, the box won't be able to withstand much pressure.
Another thing is the box design. The way the box is constructed, like the size and shape, can impact its compression strength. A well - designed box with proper folds and joints will be stronger than one that's poorly put together. For instance, a box with a reinforced bottom or side panels will be able to handle more weight when stacked.
Let's talk about how we measure the compression strength of a mailer corrugated box. One common method is the Edge Crush Test (ECT). This test measures the strength of the box when pressure is applied to the edges. It's a quick and reliable way to get an idea of how well the box will perform in a stacking situation. Another test is the Box Compression Test (BCT), where the whole box is compressed until it fails. This gives a more real - world indication of how the box will hold up during shipping and storage.
As a supplier, I know that different customers have different needs when it comes to compression strength. If you're shipping lightweight items like clothing or small electronics, you might not need a box with extremely high compression strength. But if you're sending heavy items like books or tools, you'll definitely want a box that can handle the weight.


At our company, we offer a wide range of mailer corrugated boxes to meet various compression strength requirements. For example, our PDQ Packaging Box is a great option for lightweight products. It's easy to assemble and has a decent compression strength for its size. The Drawer Corrugated Box is another popular choice. It's designed in a way that provides good protection and can handle a moderate amount of pressure. And if you need something with a bit more style and strength, our Handle Packaging Box is perfect. It not only looks great but also has a good compression strength, making it suitable for a variety of products.
We take pride in ensuring that all our boxes are tested thoroughly to meet or exceed industry standards. We use the latest technology and high - quality materials to make sure our boxes are as strong as possible. Whether you're a small business just starting out or a large corporation, we can provide you with the right mailer corrugated boxes for your needs.
