The benefits of corrugated boxes are numerous. These containers can be used to transport anything from fragile items to bulky items. You can choose from a variety of different corrugated boxes, depending on the purpose of your shipment. Read on to learn more about double-wall, unitized load, wrap-around blank, and corrosion protection. You can also use packing peanuts to pack fragile items. Here are some tips for selecting the right corrugated box for your items:
Double-Wall
Double-wall corrugated boxes are made of two layers of cardstock bonded together to provide strength and cushioning. This makes them ideal for shipping delicate goods and other items. In addition to offering increased strength, double-wall cardboard boxes also feature improved weight capacity. Whether you’re shipping a package from a business or home, this type of box is an excellent option. Read on to learn more about the benefits of double-wall boxes.
For packaging purposes, double-wall corrugated boxes are better for high-value and heavier items. They have a strong cushioning effect and absorb shock during transport. These boxes are also great for storing items for a long time. These boxes are the perfect solution to shipping heavy items. Double-wall cardboard boxes are ideal for use in house moving and other situations where extra protection is needed. The following table describes the advantages and disadvantages of double-wall boxes and how they compare with their counterparts.
Unitized Load
The feasibility of improving the unitized load of corrugated boxes depends on the size of the box and the initial top deck board thickness. Other factors, such as the board grade, can also affect the unit load. In a study, Quesenberry et al. investigated 234 unit load scenarios and found that increasing the thickness of the top deck board reduces the corrugated board grade. Increasing the thickness of the top deck board increases the overall box stiffness, while reducing the grade of the corrugated board.
In addition to measuring the compression strength of corrugated boxes, packaging engineers also evaluate warehouse and customer package receiving operations to determine if the current design is adequate for the task. Unitized load in corrugated boxes is based on the ratio of the worst loaded edges to the evenly distributed load. Stacking and unloading of the unitized load causes great stress on the corrugated box. Therefore, predicting the compression strength of the corrugated box is essential for preventing unit load failures.
Wrap-Around Blank
The advantages of a Wrap-around blank for corrugated boxes are many. The wraparound blank is more consistent in quality, and it can be packed up to twice as many cases per pallet. The RSC format requires three different machines, which consume valuable factory space. RSC machines are capable of forming multiple formats, including full-size wraparound cases, trays, and shelf-ready packages. They also save on freight costs, and require less operator intervention.
There are different types of corrugated cardboard, each with a different use. One type of corrugated board is called a ‘one-piece’ blank. The resulting box is shaped like a letter “A”. This style of box features flaps on the ends and sides, which are usually referred to as ‘flaps’. The corrugated board also has a score line, which is used to fold the flaps along the score lines.
Corrosion Protection
Corrosion protection for corrugated cardboard boxes is essential for metal products. This type of packaging is made from craft paper, PE coated craft paper, corrugated paper, or cardboard and is available in custom sizes. Corrosion protection for corrugated boxes is also available in many different types of packaging materials. For example, a corrugated box can protect a product against corrosion by containing a protective layer of Zerust paper. https://procustombox.com/corrugated-boxes/
Using Volatile Corrosion Inhibitor (VCI) packaging is another way to provide corrosion protection for corrugated boxes. This corrosion protection is an important consideration if items will be stored for over four weeks. If there is no corrosion protection, items could be exposed to a potentially corrosive sulfur equivalent for 20 years. Corrosion protection for corrugated boxes can prevent such costly and unnecessary damage.
Standard Test
Corrugated shipping boxes must meet certain standards to prevent damage and puncture. These boxes must be able to withstand varying kinds of strain, such as the weight of the contents inside. Corrugated shipping boxes may be at the bottom of a heavy pallet or stacked among different weights on a delivery truck. In either case, sudden forces can cause the corrugated boxes to rupture. Fortunately, there are a number of ways to determine the strength of moving boxes and keep them from breaking. The Mullen Test is a rigorous test designed to measure the bursting strength of corrugated boards. It is designed to simulate actual rough handling of the box.
The Mullen Test measures how much weight a box can hold, so it is an excellent choice for packing products with small spots and small gaps. The standard also specifies the minimum amount of base paper that must be present in every square foot of corrugated material. For example, a single-wall corrugated cardboard box must contain 175 pounds of base paper per 1,000 square feet of board. Contact Us
