Production Process and Capabilities
The production process of kraft paper involves several key steps. Raw materials, such as waste paper, are first fed into a pulper to break them down into a pulp.
The pulp is then processed through a series of machines, including a vibrating sieve, a pulp tank, a pulp pump, a bleach machine, and a refiner machine, to refine and clean the pulp. This process helps to increase safety and quality within the paper mill.
The refined pulp is then formed into a paper sheet using a paper making machine, which increases production speed and efficiency.
What Is the Manufacturing Process?

The manufacturing process of kraft paper is quite fascinating. The journey begins with raw material selection, where wood chips or waste paper are gathered to extract fiber pulp. This pulp is then put through a chemical pulping process, which divides the constituents and is critical in achieving the thickness, strength, and eco-friendly nature of kraft paper.
The pulping process is a key step in achieving the desired characteristics of kraft paper. The fibers separated during this process are then formed into a wet paper sheet, which forms the structure and quality of the paper.
The wet paper sheet undergoes drying using the latest drying systems available. This step is crucial in preparing the paper for industrial use. Once dried, the paper is rewound to a predetermined diameter, preparing it for packaging.
The final step in the manufacturing process is packaging, where the rolls of kraft paper are protected during movement and transportation. This ensures the paper arrives at its destination in perfect condition.

Here's a breakdown of the manufacturing process:
- Raw Material Selection: Wood chips or waste paper are gathered to extract fiber pulp.
- Pulping Process: Chemical pulping process divides the constituents and achieves the desired characteristics.
- Sheet Formation: Fibers are formed into a wet paper sheet.
- Drying Process: Wet paper sheet is dried using the latest drying systems.
- Rewinding: Paper is rewound to a predetermined diameter.
- Packaging: Rolls of kraft paper are protected during movement and transportation.
