If you’ve ever received an online order that opened like a gift, with neat folds, firm structure, and printed branding, that’s a mailer box. Custom Mailer boxes have become one of the most popular packaging choices for eCommerce businesses, subscription brands, and small sellers alike.
But what exactly are mailer boxes, and why are they so widely used? Let’s break it down.
What Are Mailer Boxes?
Mailer boxes are sturdy, self-locking cardboard or corrugated boxes designed to protect and present products without needing additional packaging tape. They typically feature a double-sided wall structure, making them durable enough to ship products safely while also looking premium.
Unlike traditional shipping cartons, mailer boxes open and close easily, offering a clean, professional unboxing experience. Many brands customize them with logos, colors, and designs to create a memorable first impression.
Common Materials Used:
- Kraft (Brown Cardboard): Eco-friendly and rustic.
- White Corrugated: Sleek, ideal for clean printing.
- Custom Printed: Fully branded with your artwork.
Can You Ship Mailer Boxes?
Absolutely. Mailer boxes are designed for direct shipping. You can pack your products inside, close the flaps securely, and ship them through postal or courier services without extra outer packaging.
Here’s why they’re ideal for shipping:
- Strong Structure: Protects fragile or lightweight products.
- Easy to Assemble: No need for extra tape or glue.
- Professional Appearance: Enhances your brand’s perceived value.
Many businesses use custom mailer boxes for subscription boxes, beauty products, apparel, and gifts. They ensure both safety and style in a single package.
How Much Are Mailer Boxes?
The cost of mailer boxes depends on several factors:
- Quantity Ordered: Higher volume = lower per-unit cost.
- Material Type: Kraft is usually cheaper than premium white corrugated.
- Printing & Finishes: Full-color printing, matte/gloss lamination, or foil stamping increase costs.
- Size: Larger boxes require more material and higher shipping rates.
