Custom Cardboard Mailer Boxes Wholesale Manufacturer USA
A mailer box has to do two things well at once: survive the trip, and make a good first impression the second it’s opened. That’s the whole idea behind a mailer box versus a plain shipping carton: it’s built to be part of the unboxing experience, not just a container the product happens to travel in.
We manufacture custom cardboard mailer boxes from sturdy corrugated stock, available in a range of thicknesses depending on what you’re shipping. Lighter items ship well in a thinner flute, while heavier or bulkier products need a sturdier build to avoid crushing or flexing in transit. Tell us your product’s weight and size, and we’ll recommend the right stock — free of charge.
Choosing the Right Base Material
The base material you choose changes how your branding reads on the shelf or at the doorstep:
- White cardboard mailers — best for bold, colorful branding or detailed graphics that need a clean, bright surface to really pop
- Kraft cardboard mailers — best for brands leaning into a natural, eco-conscious look, with muted tones that highlight simpler designs
Both are fully recyclable and take custom printing well, so the choice comes down to what fits your brand identity rather than one being objectively better than the other.
Built for E-Commerce, Subscription Boxes, and Gifting
Custom cardboard mailer boxes work across a wide range of use cases:
- E-commerce fulfillment — ship direct-to-consumer orders with branding built right into the box
- Subscription boxes — give repeat customers a consistent, recognizable unboxing experience every time
- Gifting and promotional kits — present products, samples, or press kits with a premium first impression
- Retail supplementation — support your brick-and-mortar sales with matching packaging for online orders
Add custom inserts or dividers to any mailer box order to keep multiple items secure and organized inside — useful for kitting, gift sets, or anything with more than one component.

What's the difference between white and kraft mailer boxes?
White cardboard gives bold, colorful branding a clean surface to really stand out, while kraft has a natural brown tone that suits an eco-friendly or rustic brand look. Both are fully customizable and recyclable.
What weight can a cardboard mailer box safely hold?
It depends on the flute thickness. Lighter items ship well in a thinner E-Flute style, while heavier or bulkier products need a sturdier flute to prevent crushing in transit. Send us your product’s weight and we’ll recommend the right build.
Can I add inserts or dividers to keep multiple items organized?
Yes. Custom inserts and dividers are available as an add-on, which is especially useful for gift sets, subscription boxes, or kits with more than one component.
What is the minimum order quantity?
Our minimum starts at 100 units, making it accessible for smaller and growing businesses. Larger orders reduce your per-unit cost.
Can I get a proof before my order goes into production?
Yes. Every order includes a digital proof, and a 3D mock-up is available on request so you know exactly what you’re getting before we begin production.
Is design help included, or is it an extra cost?
Design assistance is completely free. Our team can build your artwork from scratch or work from files you already have.
