What is Ply in Corrugated Boxes?

Corrugated boxes are fundamental in the packaging industry, offering varying levels of protection based on their construction. The term “ply” refers to the number of layers of paperboard used in these boxes, determining their strength and durability.

Why Choose Different Types of Corrugated Boxes?

Here are the details and information on the differences and types of 3 ply, 5 ply, and 7 ply corrugated boxes:

What Is a 3 Ply Corrugated Box and When Should You Use It?

A 3 ply corrugated box consists of one layer of fluted paper sandwiched between two layers of linerboard. This construction creates a lightweight yet moderately sturdy box. The fluted layer acts as a cushion, protecting contents from minor impacts.

• Technical: One layer of fluted paper between two layers of liner board.
• Informative: Suitable for lighter products that don’t require heavy-duty protection.
• Usage: Commonly used for packaging small consumer goods, light electronics, and inner packaging within larger boxes. For instance, retailers use 3 ply boxes for shipping clothing items or small accessories. These boxes are also popular in the food industry for bakery products and fresh produce, ensuring protection while minimizing shipping costs.

What Is a 5 Ply Corrugated Box and When Is It the Best Choice?

A 5 ply corrugated box features two layers of fluted paper, each separated by linerboard, providing enhanced strength and rigidity. This additional layer increases the box’s ability to withstand compression and puncture.

• Technical: Two layers of fluted paper between three layers of liner board.
• Informative: Balances cost and durability, making it suitable for medium-weight goods.
• Usage: Often used for shipping electronics, household items, and other products needing more protection than a 3 ply box can offer. Companies use 5 ply boxes to transport kitchen appliances, ensuring they arrive intact. They are also used in the automotive industry for shipping car parts and accessories.

What Is a 7 Ply Corrugated Box and Why Is It Essential for Heavy-Duty Needs?

A 7 ply corrugated box includes three layers of fluted paper separated by four layers of liner board, offering maximum strength for heavy-duty needs. This robust construction provides exceptional resistance to compression and impacts.

• Technical: Three layers of fluted paper between four layers of linerboard.
• Informative: Designed for the heaviest and most fragile items, requiring superior protection during shipping and handling.
• Usage: Typical uses include packaging heavy machinery parts, large appliances, and bulk industrial products. Manufacturers of heavy equipment or furniture use 7 ply boxes to ensure product safety during transport. They are also ideal for shipping large quantities of goods, such as bulk food items or beverages.
