Corrugated boxes are packaging containers made from corrugated cardboard. They are widely used in transportation and product packaging, featuring protective, buffering, and environmental-friendly properties. Corrugated carton box is composed of multiple layers of cardboard, with a wavy structure on the inner layer, which helps enhance the packaging strength and provide buffering. This structure makes them sturdy and durable, making them ideal for packaging and transporting various items.
The structure of the corrugated box
Corrugated cartons are packaging containers made from corrugated cardboard. They are composed of multiple layers of materials: the innermost layer is the liner paper, the outermost layer is a sheet of paper, and there is at least one layer of wavy inner core in the middle. There are at least three layers that are bonded together to form a stable triangular structure. This design has a very strong function of shock absorption and cushioning, and can well protect the products inside during transportation.
Different types of flute
The corrugated waves of the corrugated cardboard are like a series of connected arch-shaped doors, standing side by side in a row, supporting each other and forming a triangular structure. They have good mechanical strength, can withstand certain pressure on the flat surface, are elastic, and have good buffering effect. Below are commonly used type of corrugated box board.
1.Single-sided corrugated
Single-sided corrugated is composed of a layer of corrugated core and two layers of paper surfaces. Its features include lightness and certain strength. It is commonly used for packaging of some lightweight products, such as vegetables, fruits, books, etc. The thickness of single-sided corrugated is usually 3mm, and there are also some products with a thickness of 5mm.
2.Double-sided Corrugated Board
Double-sided corrugated board is composed of two layers of corrugated cores and three layers of paper surfaces. Its key feature is its durability and ability to withstand certain pressure and impact forces. Therefore, double-sided corrugated board is suitable for packaging of some heavy products, such as electrical appliances, ceramics, and glassware. The thickness of double-sided corrugated board is usually 7mm, and there are also some products with a thickness of 9mm.
3.Three-layer corrugated
Three-layer corrugated is composed of three layers of corrugated core and four layers of paper surface. Its features are light weight and moderate strength. It is suitable for packaging some medium-weight products, such as toys, shoes, daily necessities, etc. The thickness of three-layer corrugated is usually 5mm, and there are also some products with a thickness of 6mm.
4.Four and five-layer corrugated
A five-layer corrugated is composed of five layers of corrugated core and six layers of paper surface. Its characteristic is that it is very sturdy and can withstand a great deal of weight and impact force. Therefore, five-layer corrugated is suitable for some particularly heavy products, such as refrigerators, washing machines, furniture, etc. The thickness of a five-layer corrugated is usually 10mm, and there are also some products with a thickness of 12mm.
In summary, different types of corrugated materials have their own characteristics. One should choose the appropriate corrugated material based on the weight and nature of the product. Moreover, the quality and thickness of the corrugation also affect the load-bearing capacity and protective performance of the carton. Therefore, in packaging design, structural design should be carried out according to the actual situation.
Applications of Corrugated Paper
- Packaging Industry: Corrugated paper is widely used in the packaging of various products, such as household appliances, food, cosmetics, etc.
- Construction industry: Corrugated paper can be used for sound insulation and heat preservation in construction.
- Art Design: Corrugated paper can also be used as an artistic design material to create various handicrafts, decorations, etc.
The advantages of corrugated cardboard boxes
Corrugated paper boxes are highly favored by many consumers due to their durability, recyclability and environmental friendliness. Their main advantages include excellent buffering effect, which can well protect the products inside, low raw material cost, and recyclability. They are very suitable for use in packaging production.
1.Resisting pressure and buffering
The hollow structure in a wave-like shape can absorb 60% to 70% of the impact energy. By using wave-shaped core paper to disperse external forces, this structure can effectively protect electronic products, fragile items and other goods during transportation. If a multi-layer wave design (such as AB waves, BC waves) is adopted, the compressive resistance can be further enhanced, and its vertical load-bearing capacity can reach several hundred kilograms.
2.Low cost of raw materials
By using renewable resources such as bamboo pulp, straw and recycled paper, the cost of raw materials is much lower than that of other types of packaging materials. Significantly reduce your procurement costs.
3.Recycled and environmental protection
Corrugated paper is a recyclable material. Recycled corrugated paper can be reprocessed into new paperboard products, reducing waste and protecting the environment.
Corrugated paper, as a commonly used packaging material, has a wide range of application scenarios. Choosing the appropriate type of corrugated paper that suits your needs can better protect the packaged items and reduce losses during transportation. We hope this article can help readers better understand the classification, properties and uses of corrugated paper.
