company news about Corrugated cardboard box: How much do you know?

What is corrugated cardboard box?
Corrugated cardboard box is a box shaped container made of corrugated cardboard used for packaging and transporting goods. The vast majority of express packages we receive in our daily lives are corrugated cardboard boxes.

Why are corrugated cardboard boxes so sturdy?
Corrugated cardboard is made by bonding at least one layer of corrugated medium and two layers of flat liner board. This structure is the source of its power.
Corrugated core paper: Like a series of connected arches, this is one of the most stable structures in engineering, which can effectively disperse external impact forces and provide excellent cushioning and compressive performance.
Box board paper: Provides surface smoothness, printability, and resistance to puncture and abrasion.
This "sandwich" structure has higher strength and rigidity than solid cardboard when the material weight is the same.

What are the layer classifications of corrugated cardboard?
Single corrugated board (three-layer board): one layer of core paper+two layers of box board paper. The most common, used for ordinary transport boxes.
Double corrugated (five layer board): Two layers of core paper+three layers of box board paper. Higher strength, used for packaging heavier or fragile items such as household appliances and furniture.
Triple corrugated board (seven layer board): three-layer core paper+four layer box board paper. Mainly used for heavy-duty packaging, industrial components, mechanical equipment, etc.

What are the types of corrugated cardboard boxes?
According to the shape and size of the waves (i.e. "corrugation"), corrugated cardboard can be divided into different types to meet different needs:
A-Leng: The highest corrugated material, the best elasticity, and excellent cushioning performance are suitable for fragile items.
B-flute: The corrugations are dense and have high compressive strength, making it suitable for making hard packaging boxes and packaging for canned and bottled products.
C-rib: The thickness and performance are between A-rib and B-rib, and it is the most commonly used rib type internationally with good comprehensive performance.
E-flute: The corrugations are very fine and have a smooth surface, making it easy to print beautifully. It is commonly used for small paper boxes, display stands, etc., such as McDonald's food packaging boxes.
F Leng: Thinner and thinner than E Leng, it has been commonly used for micro packaging of high-end products such as mobile phones and cosmetics in recent years.

What are the advantages of corrugated cardboard boxes?
Excellent Protection: With outstanding cushioning and compression resistance, it can effectively protect the contents.
Lightweight: Compared to wooden boxes, plastic boxes, and other containers, it is extremely lightweight and can significantly reduce transportation costs.
Environmentally friendly and recyclable: Made from renewable resources (wood fibers), it is biodegradable and has a very high recycling rate.
Low cost: Low raw material costs, mature production processes, and overall cost-effectiveness.
Easy to process and print: It can be easily cut, folded, die cut, and beautifully printed to enhance brand image.
High flexibility: can be designed in various shapes and sizes to meet the needs of different products.

What are the main application areas of corrugated cardboard boxes?
Almost covering all industries:
Logistics transportation: express packages, storage transport boxes.
E-commerce: Direct delivery of product packaging to consumers' hands.
Food and beverage: packaging of fruits, vegetables, alcoholic beverages, and snacks.
Electronic products: inner and outer packaging of mobile phones, computers, home appliances, and other products.
Industrial manufacturing: heavy-duty packaging for automotive components and mechanical equipment.
Retail display: Designed as display racks or window packaging, directly put on shelves for sale.

How to choose a suitable corrugated cardboard box?
Choosing the right cardboard box is the key to ensuring product safety and economy:
According to the weight of the contents: This is the most basic principle. Single corrugated usually has a load-bearing capacity of ≤ 20kg, double corrugated is suitable for 20-45kg, and heavier items require double or triple corrugated.
According to product characteristics:
Fragile items: Choose A-shaped or C-shaped ribs with good cushioning performance, and match them with internal fillers.
Hard and puncture resistant products: B-rib is a good choice.
Products that require exquisite display: prioritize E and F edges.
According to the transportation environment, if the transportation distance is long and there are many transfers, higher strength cardboard boxes should be selected.
Consider size: The internal dimensions of the cardboard box should match the product to avoid excessive packaging or excessive space that may cause the product to shake inside the box. At the same time, the "stacking strength" should be considered, that is, whether the bottom cardboard boxes can withstand the weight from above during stacking.
Printing requirements: Do you need color printing to enhance brand image? This will affect the choice of noodle paper.

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.
