A corrugated box can be made out of different materials. These materials include Linerboard, multiple layers, and multiple corrugated layers. Some are more durable than others, and have a better stacking strength than others. If you are using corrugated boxes to ship your products, you should look for the following features.


Corrugated boxes are made with multiple layers of corrugated fiberboard and two layers of linerboard. Each layer has a different number of flutes to provide different strengths and cushioning for the contents. Larger flutes provide more strength and cushioning, while smaller flutes are more flexible and foldable. The original corrugated box fluting is called A-Flute, and has 36 flutes per foot. It is adequate for most shipping needs, and the smooth surface makes it ideal for printing.

The regular slotted container, or RSC, is a type of corrugated box. The outer layers of corrugated board are scored. The flaps are one-half of the width of the box, and meet in the center when folded. The flute direction in RSCs is parallel to the sheet’s length or perpendicular to it. It is also known as the end-opening RSC.

There are several types of linerboard. Some are made of recycled fibers, while others are made of virgin fibers. Corrugated boxes can be made with a single face linerboard or with multiple layers of linerboard. The type of linerboard used depends on its intended use. For instance, some are designed to be lightweight, while others are made for heavy-duty shipping containers.

The outer dimensions of corrugated boxes depend on the size of the products corrugated box being packaged. They can be ordered in small quantities or bulk. Single face corrugated is recommended for lightweight items, as the inner flutes are not visible to the outside. If you need a more sturdy box, you can use double wall corrugated board.

Multiple layers of material

Corrugated boxes are a highly customizable style of packaging that is made of multiple layers of material. These boxes are often used to package food products. Generally, they consist of multiple layers of board that are scored on the bottom surface for easy folding. These boxes can be cut to fit a variety of needs, from small to large.

Corrugated fiber boxes have an inner and outer layer of paperboard that is either coated or uncoated. The inner layer is often coated with a water-proof agent, which protects the product. The outer layer is usually printed to identify the contents and to make it visible in retail outlets.

A corrugated box is stronger than a cardboard box, and is often able to withstand greater amounts of pressure. Because corrugated boxes have multiple layers of material, they provide greater support and protection for the contents. They also offer greater customization options, such as the type of liner material, the fluting profile, and the graphics or coatings on the corrugated board.

The materials that make up a corrugated box are very strong and durable. Each layer contains multiple layers of material, including an inner liner, an outer liner, and a fluted medium. The fluted material provides rigidity to the box. This makes it more resistant to shocks and moisture. Although no container is indestructible, corrugated boxes offer a greater level of assurance and security.

Mullen test

A corrugated box’s strength is determined by how the paperboard is constructed. The thickness of a box, as well as its grammage, is an important factor in its ability to carry a load. In general, a thicker box will be more sturdy and provide more padding for items inside.

The Mullen Test for corrugated box walls is a popular test that measures the toughness of corrugated board walls. To perform the test, a rubber diaphragm applies pressure until the box ruptures. This force is measured in Kilograms per square centimetre. This test is also known as the Edge Crush Test.

In contrast, the Burst Test is the more reliable method of evaluating the strength of a corrugated box. This test is commonly used to evaluate the strength of shipping boxes. In this test, a tester suspends a corrugated box and applies increasing force to the outer face of the material.

The Edge Crush Test, also known as ECT, measures the strength of corrugated boxes while they are being stacked. This test measures the strength of the corrugated box’s top to bottom compression strength. The ECT uses fewer materials than the Mullen strength board, which sets a strict material guideline. In addition, different weights are allowed, which makes the ECT more popular.

In the 1990s, the Edge Crush Test became popular. This test measures the strength of corrugated boxes before they collapse at the edges. A box with a lower score will crush easier, while a higher number will be stronger and more durable. The Mullen Test can also be a good indicator of a box’s ability to withstand rough handling.

Edge crush test

The edge crush test for corrugated boxes is a laboratory test method that measures how resistant a corrugated board is to crushing. It measures the amount of crushing resistance and the cross-direction crush resistance of the board. This test gives the manufacturer valuable information about the board’s construction.

The test is performed using a special device called an Edge Crush Tester. It compresses a small segment of a corrugated board or box that is placed between two plates. A template is provided with the machine. After the specimen is crushed, the machine records the peak load. This value can then be used to evaluate the strength and quality of a corrugated box.

This test is an important quality control tool for corrugated cardboard factories. While it is important to ensure that the edge-crushing test is performed properly, it is not always possible to determine the stiffness of a corrugated box. A standard edge crush test is limited to measuring the strength of the edge-crush test and it requires a specimen with clean, perpendicular edges. In addition, the specimen must be free of existing damage. To avoid this problem, knives should not be used for cutting the specimen. A twin-bladed circular saw can be used instead. In addition, a precision-guided compression plate is necessary for a reliable test.

The Edge Crush Test for corrugated boxes was developed in the 1990s. The test is a laboratory-based measurement of a corrugated board’s ability to withstand crushing. Its higher number indicates a stronger box.

Origins of corrugated boxes

Before the corrugated box was invented, shipping materials was usually carried in wooden crates. These wooden crates were expensive and difficult to replicate on a large scale. The cardboard box, on the other hand, was cheaper and lighter. Despite its low price, the cardboard box faced a major problem: it was unpopular with delivery drivers. To get rid of this issue, companies like Wells Fargo put pressure on the drivers to use corrugated boxes.

It was in the early nineteenth century that corrugated paper first saw the light of day. In 1817, British industrialist Sir Malcolm Thornhill first made commercial boxes from single sheets of cardboard. Although these boxes had nothing in common with the corrugated boxes that we use today, they were incredibly useful for shipping goods. In 1856, corrugated paper was patented in England. At that time, it was mostly used as lining material for tall hats, and its practical use as a packing material was not fully realized until 15 years later.

The development of corrugated boxes was made possible by the invention of the pulping and papermaking process. In 1894, the Thompson Norris Company made the first double-sided corrugated box. At that time, the demand for paper products was growing, and the price of rags soared. Fortunately, corrugated box the Thompson Norris Company was able to meet the demand. The company then started using raw cotton, hemp, and cornstalks to make corrugated paper.

Cost of corrugated boxes

Corrugated boxes are a staple of the packaging industry and are used to protect fragile items during shipment. These boxes can be recycled and are biodegradable, making them a greener choice for businesses. They also reduce the need for wrapping materials, which is a good thing for the environment.

A recent report from the Procurement Resource includes a cost analysis of the production of corrugated boxes. It outlines all costs associated with manufacturing corrugated boxes, including raw materials, capital investment, labour, depreciation, and other expenses. This report also covers the latest trends in the industry and offers a detailed process flow diagram.

While most corrugated boxes are manufactured in the UK, the material used to manufacture them is likely to come from overseas. The weak Pound leads to higher import costs, which in turn raise energy and transport costs. Additionally, the cost of paper has risen substantially in the last year, which has made it harder for many manufacturers to access this material. Additionally, many manufacturers of corrugated packaging use foreign currency to manufacture specialist inserts and foams.

Corrugated boxes come in single and double-walled options, and can be ordered in many styles. They range from 3″ x 3″ to 40″ x 48″ x 36″. You can also find corrugated boxes with various styles, such as telescopic boxes and self-locking ones. Many of these boxes can be customized for secondary packaging.
