Custom Mailer Boxes

Mailer boxes, also known as mailers, or bulk mailers, are generally made of corrugated mailer boxes or corrugated metal, usually made of white corrugated cardboard and sometimes Kraft cardboard, commonly used in mail sorting. In most cases, mailer boxes are used to accommodate the mail items, but they are also available in custom design to meet the specifications of individual customers.

Custom mailer boxes come in various shapes and sizes, depending on your needs. You can have a package that fits inside your car’s trunk, or you can have a custom mailer box designed to provide in your office cubicle. These mailer boxes come with or without wheels.

Many companies have standard dimensions for mailer boxes. They make your selection based on these dimensions, not your specifications. To have your custom mailer boxes customized according to your specifications, you will need to provide measurements of your room or office area and the dimensions of your packages.

The company will discuss your requirements and quote you a price after evaluating your needs and box measurements. The price quoted by the company may include customizations, such as cutting corners or the size of the boxes to fit into your space.







Custom Package Pro has a team of expert designers who can help you customize your mailer boxes and packaging boxes according to your specifications. Our designers work closely with you during the conceptualization phase. This ensures that you get what you want.

There are two other options for printing these items: letter and flat rates when it comes to mailers and envelopes. There are standard sizes for envelopes and flat-rate mailers, which are the traditional boxes with inside holes. The flat-rate mailer boxes are usually cheaper because they have fewer customizations, but you can personalize them with your artwork and address labels.

We offer the following materials for your packaging needs:

  • Linen Stock

Many businesses opt for customization when it comes to their mailer boxes and envelopes. You can add foam inserts to your mailer boxes and address labels, which come in various materials and colors. Foam inserts are flexible and durable while maintaining their original appearance.

The custom mailer boxes and foam inserts are inserted into a corrugated mailer, which can be purchased already made or custom made. You can also request a custom size corrugated foam insert so that your mailer and envelopes will fit perfectly.

Exuberant coatings for mailer boxes

  • Matte

  • And a few more

If you want to offer your customers a more personal touch to their mailing experience, you can always design your mailer and packaging to suit your target audience. With custom boxes and mailer printing, you can let your target customers express themselves more for their marketing needs.

Importance of mailer boxes

If you are a homeowner, you might already know the importance of mailer boxes for your mail and packages. But you might also be a little clueless when it comes to choosing the right kind of mailbox for your home or business property.

Today, there are so many varieties of mailboxes that you can choose from. The more you know about them, the better you will be able to make an informed decision. There is a lot to learn about these boxes, including their benefits and disadvantages and how to make the most out of them.

Colorful mailer boxes are one of the best choices today. Aside from the fact that they catch the attention of anyone passing by, the color is enough to make your mail easy to spot. This means that you can entice anyone to read your mails and packages with colorful mailers.

These mailers are also efficient. Aside from the color, their contents are always in perfect condition, ensuring your protection against any damage caused by natural elements or human mishandling.

However, these mailer boxes may not be ideal in your area or location. Perhaps, you live in an area where snowfall is expected. If so, you might want to consider getting a mailbox that is designed explicitly for snowy regions.

There are white mailboxes that can keep your mail and packages safe from damage even in the snow. You may also want to ask a friend or a business partner about what kind of mailer boxes they use and see whether you can find something similar, or even better, something unique.

With this in mind, you may consider a customized box style, which may include a custom size corrugated foam insert, a custom envelope, custom address labels, and more. This may require additional expenses for your business, but it will be worth it in the long run.

Add-Ons for mailer boxes

Furthermore, you can add the following add-ons to your packaging boxes and offer an excellent and luxurious packaging experience to your customers:

  • Embossing
