Mailer Boxes vs Corrugated Boxes: Which One Do You Need?

Packaging is a critical make or break asset for online stores and e-commerce businesses. It ensures your products are efficiently stored, safely shipped, and perfectly delivered. Therefore, you have to be careful while choosing your packaging container. Picking a wrong box will either end up with overpaying for shipping or risking a nightmare of damaged returns.

For e-commerce businesses , there are two options for packaging. One is mailer boxes and the other is traditional corrugated boxes. Both the boxes look similar but they are different in terms of structure and functionality. So, if you are wondering which one will be the right choice for your business, then read this article. We will make a head-to-head comparison of mailer boxes vs corrugated boxes so that you can pick the right one for your bottom line.

What are Mailer Boxes?

Mailer boxes are self-locking packaging containers. They do not need adhesive tape or glue to close the box’s lid. They are made from E-flute or B-flute corrugated cardboard, therefore, it said that all mailer boxes are corrugated, but not all corrugated boxes are mailers.

Structurally, mailers have an attached lid, double-wall sides attached with dust flaps, and a front locking panel. The dust flaps tuck inwards and lock firmly into a place creating a tight seal. As a result they can absorb pressure and resist crushing, even if the boxes are stacked during transit.

Thanks to corrugated cardboard as a base material, mailer boxes have a smooth surface that supports full-color printing and addition of branding elements using tactile finishes. Such as embossing, debossing, and metallic accents. That’s why mailer boxes have become the gold standard of packaging for high-end brands. They are used for shipping clothing, cosmetics, jewelry, subscription services, and small consumer goods.

What are Corrugated Boxes?

Corrugated boxes are heavy-duty shipping containers. Unlike mailer boxes, they have four flaps at the top and four at the bottom. These flaps meet at the center and are either glued together with a strong adhesive or sealed with a packing tape.

Corrugated boxes are double-walled packaging containers that rely on multi-layered cushioning. The first and third layers are called outer and inner liners made from heavy-duty paper. In between these two papers is a wavy arched layer of corrugated paper which is glued securely. This arched structure is also known as flutes. The flutes act as a shock absorber, prevent tearing and puncture, and provide excellent stacking strength. This is the reason that corrugated boxes are the best packaging for small business shipping large or heavy items. Like electronics, fragile glassware, and furniture.

The Key Differences of Mailer Boxes vs Corrugated Boxes

Although both the boxes are made from the same corrugated material and sometimes look identical. But when it comes to choosing between custom mailer boxes vs shipping cartons, the difference comes down to their form and function. Following are the differences between the two that let them win over one another.

Unboxing Experience and Branding

In the e-commerce world, your box is your brand’s first and only physical handshake. In simple words, before a customer ever sees the product, they judge its quality by its packaging. And this where mailer boxes win this category. Since they have a smooth, uninterrupted surface, they allow brands to print their stories, social media handles, and signature colors inside and outside the box. Moreover, mailer boxes open like a chest that make unboxing a joyful moment. On the contrary, corrugated boxes are plain brown containers wrapped by messy packing tapes.

Durability & Strength

Although mailer boxes have double-folded dust flaps on the side-walls that make the packaging crush-resistant. Still they lose to shipping cartons in case of durability and strength. The difference lies in their fluted structure. Mailers have a thin E-flute or B-flute profile that can take the hold of lightweight items. Whereas the thick A-flute or C-flute construction of corrugated containers have the capacity to absorb external shocks and support multi-tier stacking.

Shipping & Storage Efficiency

Knowing which box is cheaper for shipping is important as it helps in saving a fortune of freight fees. In terms of shipping, mailer boxes are often more compact. This can reduce dimensional weight charges from shipping carriers. On the contrary, corrugated boxes may require extra space if void fill is needed, which can increase shipping costs. But still it’s a tie because mailer boxes are suitable for shipping products directly to the consumers. And for bulk orders corrugated boxes are the best.
Now that you know the difference between the two, let’s summarize their differences for a quick understanding.

Deciding Between Mailer Boxes vs Corrugated Boxes

If you are still stuck between mailer boxes vs corrugated boxes and don’t know which one to pick. Then don’t play a guessing game.
