The world of packaging is fascinating with all of the different types of boxes that are available. From simple cardboard boxes to complex specialty boxes, there is a box for just about everything. One type of box that is often used for packaging and shipping is double wall corrugated boxes.
What Is Corrugated?
Corrugated, itself, means a surface that is wavy or ridged. In packaging terms, corrugated is a material that is used to make boxes.
So why do they call it corrugated?
Well, one layer of this packaging is corrugated; that is, it has a wavy structure.
This layer is also known as the fluted or medium layer.
Usually, there are two liners, which are flat layers, on either side of this fluted layer. This combination of liner-flute-liner is called a single-walled corrugated material.
It is one of the most commonly used packaging materials for making custom corrugated boxes.
What Is The Purpose For The Fluted Layer?
The flutes are there to provide support and durability to the box.
This is especially important if the box will be holding heavy items. The fluted layer also gives the box rigidity, which is important for things like electronics that need to be protected from being jostled around.
How does it do that?
That’s a matter of simple structural engineering. The flutes are placed in such a way that they can support weight and provide stability to the box.
The flutes also help to absorb shock, which is important for preventing damage to delicate items. The points of contact act as shock absorbers, which is why this type of box is often used for shipping fragile items.
Furthermore, the air trapped between the ridges helps cushion the contents of the box, providing an additional layer of protection.
Why Are Liners Important?
The fluted layer may provide strength and support, but the liners are what give the box its smooth exterior.
The liner also provides a surface that can be printed on, which is important for branding and marketing purposes.
In addition, the liner helps to keep the contents of the box from coming into contact with the flutes. This is important for items that could be damaged by corrugated material, such as electronic devices.
Furthermore, the liners also help protect the fluted layer against environmental damage. Remember, the liners are more resistant to wear and tear than the fluted layer.
This is important for boxes that will be stored for long periods of time or used in harsh environments.
Types Of Liners
There are two types of liners used in double wall corrugated boxes: virgin kraft and recycled kraft.
Virgin Kraft is a type of paper that has not been recycled. It is made from wood pulp that has been bleached.
Recycled Kraft is made from recycled paper that has been bleached.
Both types of liners are equally strong and provide the same level of protection. However, recycled kraft is a more environmentally friendly option. While virgin Kraft has a slightly better printing surface, recycled kraft is not far behind. Thus, making it better for producing custom printed corrugated boxes.
Now that we have covered the basics of the corrugated material and touched on single-walled corrugated boxes let’s dive into double wall corrugated boxes.
What Are Double Walled Corrugated Boxes?
As the name implies, double wall corrugated boxes are made from two layers of corrugated material. They are also known as twin-layer or multilayer corrugated boxes.
The additional layer of corrugated material makes these boxes even stronger and more durable than their single-walled counterparts.
This makes them ideal for shipping heavy or fragile items. In fact, double wall corrugated boxes are often used for shipping electronics, glassware, and other delicate items.
The configuration of double wall corrugated boxes most commonly used by corrugated boxes wholesale suppliers is liner-flute-liner-flute-liner.
As you can see, there are two layers of fluted material with a liner in between each layer. This gives the box extra strength and rigidity.
Furthermore, double wall corrugated packaging also provides better protection against heat and moisture. The air trapped within the flutes helps regulate the temperature inside the packaging and prevents moisture from seeping in.
This is important for items that are temperature or moisture sensitive, such as food and beverages.
In addition, the extra layer of the material makes these boxes more resistant to crushing and denting. Double wall corrugated boxes can even be used for heavy-duty applications, such as shipping furniture or appliances.
However, the added strength and durability come at a cost. Double wall corrugated boxes are more expensive than their single-walled counterparts.
They are also slightly heavier, which can increase shipping costs. However, the increased protection they offer is often worth the extra cost.
When Should You Use Double Walled Corrugated Boxes?
Now that you know what double wall corrugated boxes are, you might be wondering when you should use them.
As we mentioned, these boxes are ideal for shipping heavy or fragile items. They are also great for items that need to maintain a specific temperature or be protected from moisture.
They are also great when you want to wrap heavy machinery parts in a layer of protection. If you are looking for a box that can withstand a lot of abuse, double-wall corrugated boxes are the way to go.
However, these boxes are not always the best option. If you are shipping lightweight items that do not require extra protection, single-walled corrugated boxes will suffice.
Furthermore, if you are on a tight budget, single-walled boxes are a more cost-effective option.
Can You Print On Double Wall Corrugated Boxes?
One of the biggest advantages of using custom corrugated boxes is that they can be printed with your company logo and branding information.
This helps you promote your business and build brand awareness.
Fortunately, you can print on double-wall corrugated boxes just like you would any other type of box.
The printing process is the same, and you have the same printing options available to you.
You can choose to print on the box using flexography, lithography, or digital printing.
By changing the size of the flutes, you can increase the printability of the corrugated material. Hence, you can get creative with the packaging.
For example, you can use a large flute size towards the inside of the material to increase product protection. In contrast, you can use a small-sized flute towards the outside of the packaging material to increase printability.
That will help you make custom printed corrugated boxes that are secure and aesthetically pleasing.
What To Look For When Selecting Wholesale Corrugated Boxes Suppliers?
There are a few things you should keep in mind when selecting wholesale corrugated box suppliers.
First, you want to make sure that the supplier has experience with double-wall corrugated boxes. You don’t want to get stuck with a supplier who doesn’t know how to properly manufacture these boxes.
Second, you want to make sure that the supplier has a good reputation. You can check this by reading online reviews or asking for references.
Third, you want to make sure that the supplier offers competitive pricing. Don’t overpay for your packaging just because you want double-wall corrugated boxes.
Fourth, you want to make sure that the supplier offers a variety of customization options. This way, you can get the exact type of box you need for your product.
Finally, you want to make sure that the supplier has a quick turnaround time. You don’t want your product to sit in a warehouse for weeks waiting for the packaging.
Keep these things in mind, and you should have no problem finding a great wholesale supplier of double-wall corrugated boxes.
