What is a great way to ship your products in a professional but fashionable manner? The mailer box, of course! What's the problem with the standard four-flap (0201) shipping box? Or perhaps you're wondering why the mailer box is so popular among brands. So, here's your answer… They are not only durable and long-lasting, but they are also completely customizable. 

It is an excellent way to promote your brand and provide your customers with the ultimate unboxing experience. But wait, before we get too far into this, you should know that postal boxes, mailing boxes, e-commerce boxes, and subscription boxes are all the same thing, just called differently by different people. Now that we've cleared that up, let's dig a little deeper:

Look for these mailer box characteristics

There are several features to consider when choosing the best mailer packaging box in bulk for your product. When selecting a mailer box, consider the following features:

The paper grade 

Paper Grade Durability is essential for mailer boxes, which is why they are frequently made of corrugated material. Correct, when it comes to durability, the paper grade of a mailer box is an important consideration. Most mailer boxes are made of corrugated material, which is a type of cardboard reinforced with a fluted layer sandwiched between two flat layers. This gives the box added strength and durability, making it ideal for shipping products.

Corrugated material thickness can vary, with heavier grades supplying more shelter for heavier or more fragile items. Furthermore, some mailer boxes may be made of other materials, such as recycled paper or biodegradable plastics, which can provide good durability while also being more environmentally friendly. When choosing a mailer box, consider the paper grade and the material used to ensure that your products are protected during shipping.


When selecting a personalized mailer box, closures are an important feature to consider. The method of closure you select will affect the security of your package during shipping as well as the ease of use for your customers once they receive it. Here are some examples of common mailer package closures:

Adhesive strips

One of the most popular closure options for mailer printed boxes. It consists of an adhesive strip that seals the box shut. Adhesive strips, which can be single or double-sided, provide a secure and tamper-proof closure.

Locking tabs

Locking tabs are a more secure closure option that consists of interlocking tabs on the box flaps. This method of closure is frequently used for heavier or more valuable items that require additional protection during shipping.

Tuck flaps

A traditional closure method involves folding the box flaps inward and securing them in place. This method is quick and easy, but it might not be as secure as an adhesive strip.


Velcro closures are made by attaching strips of velcro to the box's flaps. Although this type of closure is convenient and simple to use, it may not be as secure as other options.

Consider the level of security you require for your products as well as the ease of use for your customers when selecting a closure for your mailer box. A secure closure will simply guarantee that your products arrive safely and intact, whereas an easy-to-use closure will make your customer's unboxing experience more enjoyable. 


When it comes to mailer containers, printing is an important factor to consider. The right printing can help you promote your brand, improve the unboxing experience, and distinguish your package from the crowd. Here are some common mailer packaging in affordable price printing opportunities:

Flexographic printing 

Flexographic printing involves the use of a rubber plate to transfer ink to the surface of the mailer box. This method is quick and efficient, making it an excellent choice for large-volume orders.

Lithographic printing 

Lithographic printing is a more advanced printing technique that involves creating a printing plate and using it to transfer ink to the surface of the mailer box. This method produces high-quality, detailed prints at a higher cost than other options.

Custom printing

You can add your logo, artwork, or messaging to your mailer boxes using custom printing. This is an excellent choice if you want to promote your brand while also creating a professional and consistent look for your packaging.

Standard printing 

Standard printing refers to pre-printed designs or patterns that can be used on mailer boxes. If you're looking for a low-cost way to add visual interest to your packaging, this is a good option.

As a result, there will be more packaging waste in landfills and oceans. This is a huge deal for both customers and businesses. It's impossible to go a day without hearing about climate change or an environmental disaster. Consumers want the latest and greatest, but they're also concerned about the environmental impact of their purchase.

Not only does designing it take time, but your supplier must then cut it to size and print it, which has a fairly long lead time.
