Mailer Boxes vs. Shipping Boxes: Key Differences Explained

When it comes to custom packaging, mailers and shipping boxes are the two most popular options. Mailers get attention due to their elegant structure and memorable unboxing experience, while shippers are recognized as sturdy, durable packaging options, best suited for heavy items and bulk orders. Both have their own pros and cons and features, and so are the applications. At The Box Lane, we have been dealing with both kinds of packaging boxes for a long time, and we do know almost everything about them.

In this blog, we will take you to a comprehensive comparison of mailers vs. shippers. The guide will eventually enable you to distinguish them clearly and help you make an informed decision about which one to choose for your brand.

Key Takeaways

• Mailer boxes use less paper and glue than shipper boxes
• A mailer is generally more sustainable than a shipper
• A shipper box costs more for shipment than a mailer box
• Shippers are more durable and sturdy than mailers
• For single, lightweight items, a mailer is a good choice
• For heavy, bulk items, shippers are an ideal choice

Comparison Between Mailer Boxes vs. Shipping Boxes

Mailer and shipping boxes are both totally different packaging options. The following is a quick comparison of both packaging options with respect to various factors.

• Total Landed Cost

Whenever buying a product's packaging, the first question that comes to mind is about how much it will cost. Mailer boxes generally have a lower total landed cost compared to shipping boxes. It is because mailer boxes have lower material costs and reduced shipping costs. Conversely, shipping boxes require tape or padding and higher shipping costs, and that’s why they are more costly than standard mailer boxes. When purchasing in large, plain sizes, shipping boxes, however, have less cost per unit.

• Structural Design

Mailer boxes feature specific interlocking wings and flaps. It means they can adhere firmly, without needing any adhesives, glues, or sticky materials. They assemble into a sturdy, double-walled structure, necessary for product protection. On the other hand, shipping boxes follow the regular slotted carton standard. They feature four flaps on top and bottom that join in the center. A packaging tape is usually required to seal all the ends firmly together.

• Material Strength

Mailer boxes are usually manufactured from thinner cardboard material. As the flaps interlock together, they create a durable, walled structure on the edges, making them resistant to mechanical damage. On the other hand, shipping boxes are usually made from thick, single-walled, or double-walled corrugated cardboard. They are engineered to handle heavy objects and bulk loads where resistance to strong mechanical pressure is required.

• Unboxing Experience

Mailer boxes are the unbeatable kings of unboxing experience. They open like a presentation chest and allow brands to offer surprises to consumers that make them smile. For example, you can add custom inserts, branding assets, and interior printing to elevate consumer experience.

Shipping boxes are usually built for logistics, not presentation. They open from the top, usually by tearing the top, and that’s why there are very limited presentation opportunities. However, these boxes can be printed according to the brand’s preferred colors and themes.

• Cost Efficiency

Shipping boxes are generally less expensive to manufacture and have less per unit cost compared to mailer boxes. The shipping costs, on the other hand, are higher for shipping boxes compared to the mailers. It is because mailer boxes are small and can be tightly fitted in a space, leaving less dimensional weight. Shipping boxes are, however, large boxes that occupy a larger space, and that’s why they cost more for shipment. Shipping boxes also cost tape and labor hours used to adhere them firmly.

A Quick Comparison at a Glance

When to Choose Mailer Boxes

Mailer boxes are the premium choice for brands focusing on customer retention and sales. You should choose a mailer box if:

• You sell lightweight or retail products
• An unboxing experience matters
• You need branding assets inside the box
• You want to eliminate extra packing materials

When to Choose Shipping Boxes

Shipping boxes are the ideal choice for logistics. They focus on durability and cost-efficiency rather than beauty. Choose a shipping box if:

• You deal with heavy, fragile, or bulky goods
• You deliver bulk orders or multi-item shipments
• You are on a tight per-unit budget
• Your products already have retail packaging

Conclusion

Choosing between mailer boxes and shipping boxes depends on your products, marketing goals, and brand presentation goals. If you want to offer a premium unboxing experience to your customers, mailer boxes are the best application. On the other hand, if you want to focus only on functionality and cost-effectiveness, shipping boxes best meet your needs.
