What is Layer Corrugated Board Production Line?

A Layer Corrugated Board Production Line is a manufacturing system specifically designed for the production of corrugated board, which is widely used in packaging applications. This production line consists of several machines and processes that work together to create corrugated board with multiple layers, providing strength and rigidity to the final product.

The production line typically includes the following key components:

1. Corrugating Machine: This machine is the heart of the production line and is responsible for creating the corrugated layers. It consists of a series of heated corrugating rolls that apply heat and pressure to the paperboard, creating the characteristic fluted pattern. The corrugating machine can have multiple sets of corrugating rolls to produce boards with different flute profiles, such as A, B, C, E, etc., each offering different performance characteristics.
2. Glue Application System: After the corrugating process, the flute tips of the corrugated board need to be glued together to form a sturdy structure. The glue application system applies adhesive to the flutes using rollers or nozzles, ensuring proper bonding between the corrugated layers.
3. Preheating and Drying Section: The glued corrugated board passes through a preheating section where the adhesive is partially dried. This preheating step prepares the board for the subsequent processes by evaporating excess moisture and improving the bonding strength.
4. Single Facer: In this machine, a liner paper is glued to one side of the corrugated board, creating a single-faced corrugated board. The liner paper provides a smooth and printable surface for the final product.
5. Double Facer: The single-faced corrugated board is then combined with another liner paper using heat and pressure in the double facer machine. This results in the production of a double-faced corrugated board, where both sides have a liner paper attached to the corrugated core.
6. Cutting and Stacking: The produced corrugated board is cut into desired sizes using a cutting machine. The cut boards are then stacked and bundled, ready for further processing or shipping.
7. Optional Processes: Depending on the specific requirements, the production line can be equipped with additional machines for printing, die-cutting, gluing, or other processes to create various types of corrugated packaging products, such as boxes, trays, displays, and more.

Layer corrugated board production lines are highly automated and can handle large volumes of production. They offer flexibility in producing different flute profiles, board thicknesses, and sizes to meet various packaging needs. The final corrugated boards produced by these production lines are lightweight, strong, and have excellent cushioning properties, making them ideal for protecting and transporting goods.
