Definition of Mailer Boxes
A mailer box is a paperboard packaging designed to store and send your products. Thanks to interlocking flaps and wings, it is easy to assemble and requires no adhesive tape to be assembled and closed. Its double side walls make it durable and more resistant to transport than other types of paperboard packaging.
What are Advantages of Mailer Boxes?
Lightweight
Custom mailer boxes are lightweight. This means that they are easy to store and easy to ship since they don’t take up much space or weight. This also means that they are easy for customers to carry — contributing to a great unboxing experience.
Cost-Efficient
Custom mailer boxes are cost-efficient as the raw materials used to create them are affordable. They are also an in-demand product which means that packaging providers need to offer them at competitive prices.
Secure
Custom mailer boxes are secure and sturdy thanks to flaps that are able to keep contents inside without the possibility of falling out. Custom mailer boxes are also secure thanks to tough and durable corrugated cardboard that’s known for being crush-proof and puncture-proof.
Versatile
Custom mailer boxes are versatile since they come in a wide variety of different sizes and shapes to fit any and all of your products. They also come in a wide variety of different paper types, including essential white, magic white, and brown kraft paper.
Custom Size
Custom mailer boxes are, by default, customizable. For some companies, this means that you can customize dimensions like the length, width, depth, and paper type, even the ink used on your box.
Marketing Tool
Custom mailer boxes can also be used as a marketing tool by effectively branding them with your logo, colors, and fonts. When people see them on their neighbor’s front porch or in the arms of their UPS driver, they will automatically notice and likely remember your brand.
Environmentally Friendly
Custom mailer boxes are also environmentally friendly since they are largely made from recycled materials and can then be recycled themselves after use.
This means that custom mailer boxes are the perfect packaging solution for green brands. Consumers increasingly care about environmentally friendly packaging and are more willing to purchase from brands that show that they care about the environment.
Unboxing Experience
Custom mailer boxes provide customers with an incredible unboxing experience — something else that they are increasingly demanding from companies. This is because opening a mailer box feels like you’re opening a present. By adding in extra components like fillers, inserts, or your own artwork, you can further enhance the unboxing experience.
What are Features of Mailer Boxes?
Self Locking: Custom Roll End Front Tuck (REFT) mailer boxes with Dust Flaps and round flaps that tuck to secure your product in transit.
Durable Construction: Made with versatility and durability in mind, our mailer boxes can hold between 30 and 40 pounds of product.
Two-Sided Printing: Personalize the look of your custom packaging by choosing two-sided prints that compliment your brand and its message.
Full Color Printing: Don’t limit your design to just one color. With full digital CMYK printing, you can choose as many colors as your design needs without the extra costs.
Custom Dimensions: Choose custom box dimensions that fit your needs to save on material and shipping costs or choose from one of our standard custom mailer box sizes.
Digital CMYK Printing: Digital printing is more sustainable than traditional printing methods and offers a way forward toward clean, efficient, profitable manufacturing.
Eco-Friendly Packaging: Our branded mailer and shipper boxes are FSC Certified and compostable, giving you and your brand peace of mind.
Types of Mailer Boxes




Standard Mailer Box
This is the most common type of mailer boxes in the market. It is a simply designed packaging option that has wings. These wings come in handy for easy folding and unfolding of the box.
This is how a standard mailer box looks like. It has a design like an ordinary box, but with room to make customizations. For standard products, this is the type that is mostly recommended.
Mailer Box With Adhesive Sealing
The second most common type of mailer box is the one that uses adhesive sealing. While the premise of the mailer box was that it does not use adhesive materials in its making, this one does break that rule a little. But, not in the way, you might consider. The adhesive strip helps for a better sealing option. However, when unpacking the box, you have to tear the strip.
Mailer Box Without the Wing Mechanism
This one is pretty much like a standard mailer box with the only difference being that it does not have wings in it. Instead, it is packed by tucking the opening lid inside the box. They are also used widely as they are very suitable for many kinds of products. For many companies, this is their go-to choice for good reasons.
Since the opening lid is tucked inside, this type of mailer box does not require any adhesive sealing option. A mailer box without wings can also be customized and has a very minimalistic look to it.
Mailer Box With Divisions
A mailer box that has partitions made inside it, is also famous with brands. They come in handy when you need to keep the items separate from each other. It is a top choice for accessories. For instance, men’s accessories brands offer mailer boxes that have divisions for wallets, perfumes, watches, etc, all in one box.
Carton-Sized Mailer Box
Are you looking to deliver heavy-sized items to your customers, there is a mailer box type to fulfill your need. A carton-sized mailer box is used widely by many brands for shipping larger products.
Since it has a large size, it is also limited to its use. However, it is more common as compared to a mailer box with divisions.
Applications of Mailer Boxes
Hygiene and Personal Care Products
Premium personal care products put the spotlight on sustainability and ingredient quality. Discerning customers will want to make sure that the packaging is equally high-quality. Custom mailer boxes show the level of attention you put into your packaging, which your customers will surely appreciate.
Art and Educational Kits
One of the best things about mailer boxes is that you can fit one whole experience inside them. You can deliver a package of scientific experiments, one whole summer class, or basic art lessons in one box. These can be distributed as stand-alone products or as part of a student’s school activities.
Wellness Subscription Boxes
Self-care is not just a buzzword. It’s a necessity. Curated self-care and wellness packages are a common use for custom mailer boxes. The ample space lets you create and present an elevated experience. You can combine candles, bath bombs, and essential oils together with postcards, stickers, or even fragrance samples for a delightful surprise.
Holiday and Gift Boxes
Want to change things up a bit? Forego the gift wrapper and create engaging holiday-themed designs instead. Mailer boxes let you print artwork inside and outside the box, giving you plenty of room to create designs that are sure to get anyone in the holiday spirit.
Food Subscription Boxes
Food is one of the most common uses for mailer boxes. Subscription boxes rose in popularity, especially during the pandemic. You can use these boxes for freshly made fare such as cookies and pastries. A popular subscription model is rare snacks from different countries all over the world. Try it out for yourself!
Boxes for a Cause
Selling products for a charity or advocacy? Mailer boxes offer a professional presentation while letting you have a blank canvas to tell your story. You can print every detail of your cause, such as how your charity or advocacy started, who the beneficiaries are, and how your organization plans to deploy sustainable assistance so that it’s easy to digest and understand for laypersons.
Event and Wedding Supplier
Want a fancier way of presenting giveaways for your event? Offer mailer boxes instead of loot bags. Boxes let you curate and arrange the contents in a specific manner so that recipients will have a consistent unboxing experience. You can give these away as special gifts for the wedding entourage, or even everyone on your guest list, if the budget permits.
Toys and Games Subscriptions
Whether you’re crowdfunding a new game or curating rare and out-of-print ones for your subscribers, custom mailer boxes offer a nice touch to your game or toy subscription service. It protects the original packaging of the game and keeps the components intact. Create custom mailer boxes to deliver your games in engaging, colorful packaging.
Welcome Kits
Welcome new students or employees to the fold with giveaway boxes. For schools and colleges, custom boxes can contain handbooks and rules, spirit shirts, caps, and other items to offer newcomers a warm welcome. You can also use these as onboarding kits for new hires.
Cosmetics and Makeup
The beauty industry is one of the biggest users of mailer boxes. Versatile mailer boxes let you package different types of beauty products in a sophisticated way. You can combine creams and brushes in one package while keeping an air of luxury and elegance.
Jewelry and Accessories
Custom mailer boxes provide the perfect space for jewelry presentation and safekeeping. You can create boxes that are cut to the exact dimensions you require, ensuring that the jewelry inside doesn’t rattle or bump with each other, which can scratch and damage it.
Unboxing Experience
The unboxing experience is a pivotal part of the overall customer experience. It plays a crucial role in how your target market perceives your product. As such, your packaging should foster a positive and memorable unboxing experience.
Put your logo and signature colors at the front of your packaging. Doing so reinforces your branding and makes your packaging more memorable to your customers, thus creating a positive unboxing experience. With a good unboxing experience, you also build customer loyalty and encourage repeat purchases.
Point of Purchase
Will your customers purchase your product in-store or online? You should design your packaging according to how your customers will purchase your product.
If your products are going on display on store shelves, the design of your packaging needs to stand out. Unique packaging helps differentiate your product from other products on the same store shelf and makes it easier for customers to spot.
On the other hand, online purchases mean you’ll have to ship your product. Therefore, you should design your packaging in a way that protects the product within so that it doesn’t get damaged in transit. For online purchases, high-quality, durable, and customizable mailer boxes are the ideal type of packaging to use.
Sustainability
Now more than ever, people are conscious of the environment, and they actively engage in environmentally friendly practices such as recycling. Many customers also want the brands they buy from to be sustainable and care for the environment.
When designing your packaging, prioritize sustainability. Use eco-friendly and sustainable materials to create your packaging. It’s also a good idea to create reusable packaging so that customers don’t just throw it away after unboxing the product.
Size and Shape of the Packaging
Size and shape are critical factors to consider when designing your packaging.
If your product is going on display on store shelves, the size and shape of the packaging will affect how easily potential customers notice your product. The size and shape will also affect how stores display your product on their shelves. If the packaging is irregularly shaped and too bulky, stores may not display it prominently on their shelves.
Material
The material of your product should be sustainable, high-quality, durable, and be able to protect the product within. A material like this naturally be more expensive, but it’s worthwhile to invest in high-quality packaging material that will protect your product and prevent it from getting damaged as it moves through the supply chain.
Corrugated board is an ideal packaging material. It’s lightweight yet durable, which means the contents of your packaging will be safe and secure. Corrugated board can also be made into a wide range of sizes, making it suitable for packaging your product whether you will sell the product or in-store.
Cost
Consider your budget when designing your packaging. Extravagant packaging with unique designs may be nice for your customers to look at, but they can be expensive to manufacture. You need to make sure that the design for your packaging fits your budget.
That being said, creating budget-friendly packaging doesn’t mean you have to go with just a plain box. Nowadays, you can still create a custom packaging design with all the designs, logos, and colors you want for an affordable price.
Branding
The last—but certainly not the least important– factor to consider when designing your packaging is your branding. To reinforce your brand, your packaging must have these elements such as:
Colors – Your brand’s colors are significant because people normally associate colors with specific brands. For example, when people think of Coca-Cola, they think of the colors red and white.
Logo – Your logo needs to be at the forefront of your packaging because the logo is another element that makes a product or brand instantly recognizable. For instance, everyone around the world is familiar with Nike’s “checkmark” logo.
Copy – When designing packaging, it’s best to avoid going overboard with the written copy. Try to keep your copy simple but punchy. Most customers won’t bother with reading large walls of text on product packaging.
Images – If you want to put an image on your packaging, make sure you have a high-quality image file to provide to whoever is going to manufacture your packaging for you.
