Choosing the right boxes for packaging is vital. There are several options from which to choose, and the prices vary just as much as the features. While you may be inclined to choose the lowest priced option to reduce your shipping costs, doing so could result in products being damaged during transit. Using the wrong packaging materials could also lead to a lot of unnecessary frustration and wasted time.
While there are several factors that must be taken into consideration when purchasing boxes, one of the first decisions you will likely have to make is whether you want single or double wall boxes. We offer both single wall and double wall custom boxes. Let’s take a closer look at each to determine which is the best fit for your needs.
Corrugated cardboard boxes are widely used for numerous applications, including shipping, packaging, storage, moving, etc. They come in single wall and double wall varieties, but both are made of a fluted paper sheet sandwiched between two sheets of liner paper. The inner and outer layers may be made from Kraft paper, test paper, recycled paper or semi-chemical paper. Most often, Kraft paper is used for the outer layers while test paper is used for the inner layer. The flutes vary in size, and the durability and strength of each box depends on the size of the flute and the types of paper used.
Single wall boxes are designed using just one layer of fluting. They are the type of box that is most commonly used for shipping in the e-commerce industry, and for good reason. Single wall boxes are economical, and they provide the cushioned protection and rigidity that is necessary in a shipping container.
Corrugated cardboard consists of a fluted corrugated sheet and one or two flat liner boards. The flutes run parallel to the box’s depth and provide its rigidity and strength for stacking. They also provide insulation to protect box contents from sudden temperature changes.
Flutes come in various sizes. Short flutes offer a greater degree of crush resistance than larger flutes, but larger flutes absorb more shock and provide more protection. As a result, the larger fluting is commonly used in single wall boxes.
A, B, C and E flutes are commonly used in single wall boxes. The A flute is the thickest and provides the greatest rigidity for stacking. B flute is commonly used for die cuts while C flute is a common choice for shipping goods. E flute is very thin compared to the other ones, and it is commonly used in custom printed boxes. Boxes constructed using this material are for packing, moving and storing lightweight goods. They are not appropriate for heavy items.

Double wall boxes are created using two layers of fluting instead of just one. The layers are usually different sizes to combine the benefits of various flute types. Double wall boxes feature 5-ply construction which provides a great deal of strength. This makes them an ideal choice for heavier items and products that require a greater deal of protection than what a single wall box can provide. Because they are more rigid, double wall boxes are also a better choice than single for long-term storage.
Double wall flutes are usually made using B and C flutes. However, they may also be made using combinations like A/C, B/C or B/E. Such combinations are most commonly used for heavy-duty containers. The extra padding and rigidity makes them appropriate for carrying heavy goods. Due to their strength and durability, double wall boxes are used in manufacturing facilities and retail outlets.

When shopping for custom boxes, consider how they will ultimately be used. Are you using them as packaging for small, lightweight items? Or do you need boxes for shipping or storing heavier products? What does your budget look like? Custom double wall boxes require a larger investment than custom single wall boxes, but they could save you the expense of damaged products and the frustration of boxes that do not stack neatly.
We offer a wide variety of single wall and double wall custom boxes to suit any application. We have everything you need to store, ship and transport products of all shapes and sizes, and we would be more than happy to customize corrugated cardboard boxes that are perfect for your business.
