Publish Time: 2023-10-18
In the modern logistics and packaging industry, corrugated cardboard is a widely used multi-functional packaging material. It is lightweight, environmentally friendly, and durable, providing flexible and reliable packaging solutions for all walks of life. This article will take an in-depth look at the characteristics, production processes and applications of corrugated cardboard in different fields.

1. Characteristics and advantages of corrugated cardboard
Corrugated cardboard is composed of corrugated core paper between a layer of paper and a layer of textured paper. It has the following main features and advantages:
- Lightweight and environmentally friendly: Corrugated cardboard is mainly made of paper, which is lighter and easier to handle than other packaging materials such as wood or plastic. At the same time, the paper can be recycled, making it an environmentally friendly packaging solution.
- Durable and compression-resistant: Corrugated cardboard provides good compressive strength through the structure of the corrugated core paper, which can withstand heavy pressure and stacking and protect the packaging from damage. This makes corrugated cardboard a reliable choice for packaging and shipping a variety of products.
- Good buffering performance: The corrugated core paper of corrugated cardboard can effectively absorb and cushion, preventing damage caused by vibration, shock and shock to the packaging during transportation. This makes corrugated cardboard widely used in protecting fragile and high-value items.
- Production flexibility: Corrugated cardboard can be flexibly designed and produced according to packaging needs. By adjusting the density of the corrugated core paper, the thickness of the surface paper, and the combination method, different requirements such as strength, waterproofness, and damping properties can be achieved.

2. Manufacturing process of corrugated cardboard
The production process of corrugated cardboard is somewhat complex and mainly includes the following steps:
- Corrugated core paper production: Corrugated core paper is formed by squeezing and producing textured paper through the forming rollers of the corrugating machine. The selection of textured paper and the forming process have an important impact on the quality of cardboard.
- Tissue paper bonding: Lay the tissue paper on both sides of the corrugated core paper, and use adhesive materials such as hot melt glue or water-based adhesive to bond them together. The amount and uniformity of the adhesive need to be controlled during the bonding process.
- Finished product cutting and folding: Cut corrugated cardboard into desired size and shape as needed. Common cutting methods include manual cutting and automatic cutting machinery. The cardboard is then folded into the desired structure or shape according to the requirements of the product packaging.
- Printing and Decoration: Depending on the brand identity and needs, corrugated cardboard can be printed and decorated to enhance the appearance and appeal of the product. Common printing methods include screen printing, flexographic printing and digital printing.

3. Applications of corrugated cardboard in different fields
Corrugated cardboard has a wide range of applications in various industries. Here are some common application areas:
- Food industry: As one of the main materials for food packaging, corrugated cardboard is widely used in cartons, trays, paper bags and other packaging. It protects the freshness and quality of food and provides good water and moisture resistance.
- Electronic products industry: Corrugated cardboard is used for packaging and transportation of electronic products, such as televisions, refrigerators, washing machines and other large home appliances. It provides good cushioning and compression resistance to protect products from damage during transportation.
- E-commerce industry: With the rapid development of e-commerce, corrugated cardboard plays an important role in express delivery and parcel transportation. It is used to make various cartons and cabinets to provide safe and reliable transportation protection for products.
- Wine and beverage industry: As a packaging material for wine and beverages, corrugated cardboard can provide good compression resistance and shock-proof properties to ensure that the product is not damaged during transportation and storage.
- Furniture and home furnishing industry: Corrugated cardboard is widely used in the inner packaging and protection of furniture and home products. It provides cushioning and compression resistance, protecting the surface and structural integrity of the product.

As a multifunctional packaging material, corrugated cardboard plays an important role in the modern logistics and packaging industry. It is lightweight, environmentally friendly, durable, pressure-resistant and has good cushioning properties, providing flexible and reliable packaging solutions for products in different industries. Through precise manufacturing processes and personalized designs, corrugated cardboard can meet various packaging needs and provide product safety protection and visual appeal. With the development of the logistics and packaging industries, the application prospects of corrugated cardboard will continue to expand, bringing more possibilities to product packaging in various industries.
