What is the definition of corrugated cardboard box?
Corrugated cardboard box, commonly known as cardboard box or paper box, is a container made of corrugated cardboard used for packaging and transportation. It is one of the most widely used and important packaging forms in the global logistics and retail industry today.
1、 Core Structure and Materials
The core of a corrugated cardboard box lies in the corrugated cardboard, which is usually composed of at least one layer of wavy corrugated core paper (commonly known as "pit paper") and one or more layers of flat cardboard (face paper) bonded together.
Structure: This "sandwich" structure endows the cardboard with extremely high mechanical strength while maintaining its lightweight characteristics. The corrugated arch structure can disperse external forces and provide excellent cushioning and compression resistance.
Material: The main raw material is wood pulp or recycled pulp, which makes corrugated cardboard boxes recyclable and biodegradable.

2、 Main features and advantages
Excellent protection: It has good compressive, burst, and cushioning properties, which can effectively protect the contents from impact, vibration, and compression during transportation.
Lightweight and sturdy: Lightweight can reduce transportation costs, while high strength can meet the packaging needs of most products.
Low cost: With a wide range of raw material sources, mature manufacturing processes, and relatively low production costs.
Easy to process and design: Easy to cut, fold, print, punch, die cut and other processing, can be made into various shapes and sizes of boxes, and printed with exquisite patterns and logos.
Environmentally friendly and recyclable: mainly made from renewable plant fibers, it is easy to recycle and reuse after being discarded, in line with the concept of modern green packaging.
Good stacking performance: The regular box shape facilitates stacking during storage and transportation, saving space.
3、 Types of corrugations (corrugation type)
According to the height and density of the corrugated material, it is mainly divided into the following types to meet different packaging needs:
A-Leng: Corrugated is the highest, with the best cushioning performance and elasticity, suitable for fragile items.
B-flute: The corrugations are dense and short, with high compressive strength on the flat surface, suitable for making cardboard boxes with high hardness and flatness requirements, such as canned food and beverage packaging.
C-notch: Between A-notch and B-notch, it has good comprehensive performance and is the most commonly used notch type.
E-flute: The corrugation is very fine and has a smooth surface, making it easy to print with high quality. It is commonly used in small paper boxes, display packaging, etc.
F flute: finer than E flute, used for high-end boutique packaging, with excellent hand feel.
In addition, there are also combinations of double-layer corrugated materials such as AB and BC, which are used for heavy-duty packaging that requires ultra-high strength.
4、 Main application areas
The application of corrugated cardboard boxes covers almost all industries:
Logistics transportation: the outer packaging of various goods during transportation.
E-commerce express delivery: It is the most important form of packaging for e-commerce packages.
Food and beverage: outer packaging of fruits, snacks, alcohol, instant noodles, etc.
Electronic products: packaging boxes for mobile phones, home appliances, and other products.
Moving and warehousing: used for individuals or businesses to move and store items.
Retail display: The beautifully printed and die cut cardboard boxes can be directly used as sales display racks.
5、 Common box structures
RSC: The most common standard box type with two top and bottom cover plates.
Heaven and Earth Cover Carton (HSC): Composed of a separate lid and bottom, commonly used for gift boxes and clothing boxes.
Folding cardboard box: It can be folded into a tray shape and is commonly used for collective packaging of large or bulk goods.
Irregular box: Various complex shaped cardboard boxes made through special die-cutting processes, used to create unique packaging effects.

Summary
Corrugated cardboard boxes are the cornerstone of modern business and logistics. With its unique structure, it perfectly balances protective performance, cost-effectiveness, processing convenience, and environmental friendliness, becoming an almost irreplaceable packaging solution. From protecting a precious piece of porcelain to delivering thousands of e-commerce packages to consumers, corrugated cardboard boxes silently play a crucial role.
