Material for Custom Mailer Boxes

Classic White

A matte finish is the most popular option. This is characterized by a non-glossy, flat appearance that absorbs light, making colors muted and subdued.

Premium White

A satin finish is available on premium white cardboard, with a slightly glossy appearance reflecting light, allowing colors to appear more vibrant and lustrous.

Kraft (Brown)

This cardboard type is known as natural Kraft and allows you to print minimal designs that exhibit dull colors. It provides a natural look, which is best for eco-friendly concerns.

Material Thickness of Mailer Boxes

Thickness of the mailer box material is usually measured in terms of “flute” for corrugated cardboard. Common flute sizes include A, B, C, E, and F, with A being the thinnest and F the thickest.

We manufacture mailer boxes from 1/16 inch (E-Flute) for single-wall boxes or 1/8 inch (B-Flute) or thicker for double-wall boxes.

Frequently Asked Questions

We’ve answered all the questions you may have before ordering a box.
What is your minimum order quantity?

The minimum order limit is not applicable; you are free to order any number of boxes that you need.

Can I get the dieline template?

Yes, you can get the dieline template for your mailer boxes.

What is the difference between mailer boxes and shipping boxes?

Mailer boxes are designed for lightweight items, often with customized branding, suitable for e-commerce. Shipping boxes are heavier, sturdier, and used for bulkier, heavier items during transit.

What is your turnaround time?

We will start work on your order as soon as you finalize the quote. Our priority is to deliver it within 7 to 10 working days.

Can my mailer boxes be shipped assembled?

Assembling your custom mailer boxes is your responsibility after receiving them because they are delivered unassembled.

Is shipping the items without any external packaging in a mailer box possible?

Although mailer boxes appear sturdy enough to protect the product, some external packaging would be recommended for increased safety.

Which size mailer box should I choose for my product?

To allow room for packing materials such as bubble wrap and packing peanuts, measure your product and choose a mailer box slightly larger than it. Do you need help measuring the product? Take a look at this guide.

Can I design my mailer box with ECB?

Yes, our creative designers will create it for you, but you will have to pay for our design services. We will share the design with you before printing. If any changes are required, we will make them.
