There are many types of corrugated boxes, which can be roughly divided into three categories according to their structure:

Slotted carton (type 02)

The slotted carton is the most basic type of transport packaging and is the most widely used carton. It is a carton made up of one or several pieces of processed corrugated cardboard that are combined by nailing or bonding. Its bottom and top flaps (upper and lower flaps) form the bottom of the box and the lid. Such cartons can be folded and laid flat during transportation and storage, and have the advantages of small size, convenient use, sealed and dustproof, and clean inside and outside.

Casing type carton (type 03)

The nested carton consists of one or several pieces of processed corrugated cardboard, which is characterized in that the box and the lid are separated and are fitted during use. The advantages of such a carton are that it is convenient for packing and sealing, and it is not easy to fall off after the goods are loaded, and the overall strength of the carton is higher than that of the slotted carton. The disadvantage is that after the synthetic type is large, the transportation and storage are inconvenient.

Folding carton (type 04)

Folding cartons, also known as shaped cartons, are usually made up of a piece of corrugated cardboard that is folded to form the lower, side, and lid of the carton without the need for stapling and bonding.

Corrugated box accessory

In order to protect the goods from damage during transportation, according to the characteristics and requirements of different commodities, it is necessary to design a reasonable structure to protect the goods. The most basic carton accessories are the following:

A. Gap: For the packaging of fragile and fragile items in bottles, separate the items in the box to prevent shaking and collision.

B. Lining: The lining is basically composed of three, one is a full lining, used for multi-layer stacking in the box for stratified isolation. The second type is a bridge lining, which is used for the flap inside the carton to cover the gap. The third type is a collar. To improve the compressive strength of the carton and protect the merchandise, the liner is surrounded on all four sides of the carton.

C. Liner: According to the different shapes and weak parts of the product, various liners are designed to fix the goods, ensuring that the goods are not moved during transportation and have a buffering effect.

Advantages of corrugated boxes

Corrugated boxes are paper-wrapped containers made from corrugated cardboard, which have a lot of points:

1. Light weight and good structural performance. The corrugated structure inside is similar to the arch structure, which can play the role of anti-shock and shock absorption, and has good mechanical properties.

2. There are many good protection functions for packaged articles. For example, moisture, heat, and easy handling.

3. Low transportation costs and easy mechanization and automation of packaging and transportation.

4. The specification and size changes are easy to implement, can quickly adapt to the packaging of various items.

5. It is convenient to seal and bundle, and it is easy to automate.

6. Can adapt to the decoration and printing of various types of cartons, can solve commodity protection and promotion problems.

7. The waste bin is easy to recycle and reuse, and meets environmental protection requirements.

8. It can be greatly expanded by combining various coverings or moisture-proof materials.
