Discover The Secrets of The Folding Box Board

A folding box board is a type of paper-based material used for making boxes that are designed to be folded and glued rather than assembled with staples or sewn. it is also known as carton board or cardboard, and it comes in large sheets or rolls that can be printed, cut, and scored (creased) to form the structure of boxes and other packaging containers.

Production Process

The production process for folding box board, alsoThe production process for folding box board, also carton board, involves several involves several stages that transform paper pulp into a sturdy material used for making boxes that are foldable and rigid. Here's an overview of the process:

Raw Material Preparation: The production begins with the selection and preparation of raw materials, typically consisting of a mix of virgin wood pulp and recycled paper fibers.

Pulping: The raw materials are mixed with water and chemicals to create a pulp. This pulp is then cleaned and screened to remove impurities.

Refining: The pulp is refined to ensure the fibers are of the appropriate length and consistency for the desired grade of paperboard.

Forming: The refined pulp is fed onto a paper machine where it is formed into a sheet on a moving wire screen. The forming section controls the distribution of fibers to ensure an even thickness.

Pressing: After forming, the wet sheet is pressed to remove excess moisture by passing it through rollers.

Drying: The pressed sheet is dried using steam-heated dryers that evaporate most of the remaining water, leaving the sheet with a small percentage of moisture.

Sizing and Coating: Depending on the type of folding box board being produced, additional treatments such as sizing (to make the surface less porous) and coating (to provide a smooth finish for printing) may be applied.

Calendering: To improve the smoothness and printability of the board, it may undergo calendering, which involves pressing it between rollers to achieve the desired finish.

Winding: The finished board is then wound onto large rolls for storage or further processing.

Converting: The rolls of paperboard are then processed through a converting line where they are slit into panels, printed (if required), and die-cut into blanks that have crease lines for folding.

Scoring and Cutting: Scoring blades create indentations in the board that allow it to fold cleanly alon lines. Cutting knives then trim the board into flat forms that can be folded into boxes.

Folding and Gluing: The cut and scored blanks are then folded into the shape of a box on a folding machine, and glue is applied to secure the flaps.

Quality Control: Throughout the entire process, quality control checks are performed to ensure that the board meets the required standards in terms of dimensions, weight, stiffness, and print quality.

Packaging and Shipping: The finished box boards or pre-glued and folded box components are packaged carefully to prevent damage during storage and transportation. They are then ready for distribution to customers or for further manufacturing processes such as box assembly.

This process can vary depending on the specific type of folding box board being produced and the equipment used, but these steps outline the basic stages in the production of folding box board.

Usage scenarios of folding box board

Folding box board, also known as carton board or cardboard, is used primarily for the manufacture of paper-based containers and packaging for a wide range of products. Here are some common uses:

Retail Packaging，Shipping Containers，Storage Boxes，Product Displays，Food Packaging,Medical Packaging,E-commerce Packaging, Beverage Packaging,Mailer Boxes,Custom Packaging

The production of folding box board is designed to cater to these diverse needs by offering different thicknesses, stiffness, and surface treatments to accommodate various printing and converting processes. The ability to fold and glue the board into shapes makes it an efficient and versatile material for packaging applications.
