You use a variety of goods and products every day, and these goods and products are packaged. Packaging requires securing and transporting materials while they are being transported, handled and stored. Packaging materials must have the essential properties required for storage. They should be durable, economical, lightweight and environmentally friendly. Corrugated boxes are such a material. It is one of the most accepted transportation materials today.
The design and strength of the materials used (to make corrugated boxes) must be analyzed to determine the safety, quality and durability of the packaging materials. There are many factors that help determine the strength of paper.
The number of layers and their importance
Lined board and corrugated paper are used as materials for making corrugated boxes. Corrugation is the grooving of paper. The paper passes through corrugated rollers to obtain these corrugated paper materials, which is one of the most unique aspects of corrugated boxes. When making the box, these fluted papers are placed between the lined cardboard. Corrugated paper has a column of air that acts as a buffer and supports the weight of the product packaged in the box, making it superior to other types of boxes.
The combination of lined cardboard and corrugated paper provides a higher strength product that can be used for a variety of purposes. Depending on the type of corrugated paper used, the characteristics of the corrugated box will change. The strength of corrugated boxes can be divided into three layers, five layers, seven layers and nine layers. Depending on the type of product used and the treatment required, the number of layers in the box may vary.
For example, a 3-layer corrugated box will place a sheet of corrugated paper between two layers of cardboard. This kind of box is suitable for transporting and storing jewelry, toys and other products that are not heavy and delicate. Similarly, (5-ply corrugated box) will consist of 3 lined cardboard and 2 grooved paper clamped together. The boxes can withstand stress and can be stacked for easy and low-cost storage or transportation. The seven-layer box is usually used for heavy items, such as metal parts and chemicals. The 9-layer corrugated box is made of high quality kraft paper. It has very thick walls that increase its strength capability, can be used for heavy duty packaging, and can last longer than 5 – and 7-layer stacks.
Advantages of corrugated boxes
(Corrugated boxes) can be folded and cut into various shapes and sizes due to their structure. The strength of the box varies depending on the number of layers. The myriad sizes and shapes of boxes are one of the main reasons for their versatility. While glasses and products that require higher strength and cushioning require higher layers, most everyday corrugated boxes use lower layers.
Regardless of the number of layers, these boxes are used to help preserve the value of the object or material being packaged. In addition, you will find that boxes with a lower number of layers can be used as inherent attachments to the corrugated box itself or other types of boxes during the transportation of goods. They limit the movement of materials inside the box, thus avoiding damage during transportation and storage. In short, corrugated boxes are one of the most effective packaging materials known and are therefore widely used in a variety of industries.
