How custom kraft boxes work 

If you want to create a strong brand that really stands out, then you need to have a distinct and memorable image. It’s a lot easier to create an image for your brand if you have custom corporate boxes to work with. Custom boxes give you the opportunity to explore a lot of different ideas and designs that you can use to create a truly memorable image.

There are many variations of generic office supply boxes available in commercial stores, including cereal boxes, snack packs, paper projects, and envelopes. No matter what kind of box you choose to use, you need to cut out every single square inch of it. That’s because the entire purpose of using a custom box is to protect your products with extra layers of cardboard.

That’s where the inner corrugated cardboard sleeve comes into play. It provides additional protection to the inner box from having to deal with harsh environmental circumstances.

But you need to remember that you’re not moving to a fancy corporate penthouse at the end of 2020. Kassie’s Box offers a variety of inexpensive, value-priced boxes ranging in widths from 19.75 to 27.75 inches.

Office Supplies

If you’re looking to replace your office supplies or snacks boxes, your options are limited to those made from corrugated cardboard. As corrugated cardboard tends to be more expensive than locker-purchased cardboard boxes, it’s the cheaper option that you should use.

But really, there’s a lot of flexibility in using any kind of outer cardboard box you have. Most office supply boxes have a square shape, so you can buy a customized one to fit your business.

The kraft printing process somehow combines paper and cardboard to create an interesting image that adds further to the unique personality of your boxes. The true charm of kraft printing is that it really can be done any way you want — simply enough. Maybe you need a custom red box to make everything pop. Maybe you want to use green paper on a bigger white box to try to achieve a more peaceful image.

The benefits of using custom kraft boxes

Custom kraft box packaging is not just a great way to package your products; they’re also a great way to make your brand memorable. When your customers receive your products in a custom kraft box, they will remember your company and associate their positive experiences with your brand.

How do you pack a custom kraft box? 

You’ll want to choose a box that is big enough to contain your products and sealed well. I suggest sticking to a rectangular box measuring at least 3.75 x 8.75 x 7.25 in as I believe this works with most corrugated cardboard boxes. You’ll also want to seal the inside with a silicone sealant.

If you’re using a shipping company, you’ll want to make sure you have a good relationship with them. Customers should expect to receive your boxes promptly, and the shipping company should always deliver the boxes as advertised.

There are lots of reasons to use custom boxes, so let’s dig in a bit deeper on each one. Here is a list of benefits you can reap from using custom kraft boxes.

When you’re shooting this video, you can see how to best position corrugated cardboard for folding and how to seal the box.

With an extruded corrugated cardboard sleeve, you get a flat piece of cardboard that holds its folded shape without any gaps. This saves you from extra folding and packing volumes.

Don’t believe me? Try creating a shopping cart project without sleeves. You can see what a difference it makes.

Several times I’ve created product catalogs one color thicker than the majority of my market. I’ve created catalogs of graphic t-shirts, mugs, jewelry, and more that were way too thick but had better legibility when printed on standard printer paper.

When customizing your products for mailing, the motto isn’t to “pack it thick and punch it small.” It’s more about the “Punch it Medium.”

What are the components of a custom box?

 A word about the components of the custom box: The custom box is made up of three parts: 

(1) the box itself

(2) the liner

(3) the lid

The box itself is made of corrugated cardboard, which is 100% waterproof. You can find corrugated cardboard in any office supply store for $2 per 100 square feet, and it can last several years in your home. 

The inside of the box is where the actual product is packaged. You’ll find foil or plastic to protect your product from harmful environments, such as floods and hurricanes. The actual paper sleeve that’s used on the outside of the box is made of sustainability harvested cotton or hemp. 

Cotton or hemp are biodegradable fibers that can be incinerated after being printed onto paper. In order to find sustainable fibers, you need to research the companies producing Eco-friendly boxes inside your store. Note that there are no harmful ingredients when using biodegradable fibers. Plus, this type of box can be reused more times without storing the cardboard inside a landfill. Here’s a great article from Eco Drain that explains the material inside the box.

You’ll need a prescription before ordering custom boxes and the paper on your box needs to be 100% recycled. 

How often you will use your custom kindling box depends on what your products entail. For furniture and small household items, you’ll want to use them at least every six months. For more health-related goods, like bathroom and bath tissues, make sure to use them within three months of purchasing them for optimal results.

How to make a box from scratch

If you want to make a box from scratch, start by creating a simple template in Excel. This template should have two columns: one for the length of the box and one for the width. Also, make sure to add a row for the front and back of the box. Next, you’ll need to figure out the depth of your box. Manufacturers typically advise adding a 1-foot depth to avoid seams. Or, if you have an industrial PC, you can use the template to determine your box thickness. Either way, you need to calculate your box length before folding it.

Next, you want to seal your inner box. At Home Depot and Target, the yellow outer cardboard sleeve is sewed into place on the inside of the box. This outer sleeve is typically made of polyvinyl chloride (PVC) and will not affect the strength of your box. However, if your box has a rough edge and your local hardware store sells pliers, you can buy an outer sleeve made of paracetamol (PVA). Use a 4-foot strip to prevent the box from being twisted or jiggled around.

We found it easier to seal boxes with a caulking gun, which uses a mild solution rather than requiring a lot of pressure. A caulking gun costs about $35 and should last forever. Just make sure to wipe down the gun before and after each use.

Now, it’s time to design your inner box. Layout all your boxes, as well as all of the boxes in your cart (if you have more than one shipping item). Product photos are helpful for illustrating your box’s features, but you can also design a box layout if it works better with your colors.

How to make a sleeve for your custom kraft box and how to seal it

To make a sleeve for your custom kraft box, first, fold the box in half and trace the outside edges onto a sheet of paper. Then cut out the paper along the traced lines and fold it in half. Next, open the paper up and place it inside the box, lining up the edges with the inside of the box. Next, add a double layer of corrugated cardboard and cover the entire thing with that. Finally, tack on a waterproof membrane to the top and seal it using glue.

The main disadvantage of custom kraft boxes is their price. If you choose to purchase them, you’re paying a premium of several dollars more for the durability, aesthetics, and surety of the envelope. Still, even for retailers, custom boxes can be a valuable part of the online marketing mix. So, let’s take a look at five reasons you might want to try custom kraft boxes.

One of the first things you should consider when customizing your boxes is customer feedback: what do customers love about your product? For some companies, it’s the design. For others, it’s the insulating qualities or the easily transportable function, or for another company, it’s the unique inner sleeve that brings out the flavor more. You may find that your customer had a favorite aspect about your product that you could improve upon by adding to the box in a certain way.

Usually, when people talk about “customer feedback,” they’re referring to positive reviews. But a cool thing you can do is analyze and warn customers who love the color or material of your inner sleeves before production starts.


Custom kraft boxes often include a stock image of the product inside. And every time you publish a box that allows consumers to pick their own inner sleeve, you’re opening up new potential for sales. If customers can easily choose a sleeve of their choice when backing a box, they may be more likely to pick it up and use it. You can get the best custom kraft packaging boxes at a wholesale rate. You just need to search the internet for custom packaging near me, you will get the list of some of the best packaging services available on the internet.
