What Is The Traditional Method Of Manufacturing Kraft Paper?
The traditional manufacturing process is similar to the new method but it uses older equipment and less advanced technology for process control. If you also need traditional paper for wrapping meat and other seafood items, hurry up and place your order for custom butcher paper sheets.
Here are some steps in the traditional manufacturing of kraft paper:
Wood Chipping And Cooking
At first, remove the bark from the wood and then cut the wood into small chips through the chipper. This process makes the cooking more convenient and consistent. Then these wood chips are cooked with liquor in a large digester at a high temperature.
Washing And Screening
After cooking, there are some chemicals left in the dissolved material. The washing process removes the black liquor and other unwanted chemicals to clean the pulp. Then the screening process filters the uncooked particles from the pulp to improve its quality.
Bleaching
The bleaching process is optional. This process increases the brightness of the paper and it is not required for brown kraft paper. It is important for white kraft paper.
Forming
After the bleaching or unbleaching process, the material is diluted with water and spread on the paper machine for forming the sheet.
Finishing
After forming, the paper is dried with traditional methods and then some finishing details are added, like checking the quality, size and weight of the paper material.
New Methods Of Manufacturing Kraft Paper
Initially, kraft paper was used as traditional paper, but in this modern era, people now want to use more durable and recyclable paper. That’s why manufacturers discover new methods of manufacturing kraft paper to meet the customers’ requirements.
New methods of kraft paper packaging use various raw materials, which are listed below:
- Softwood pulp
- Softwood fibers
- Hardwood fibers
- 100% recycled material
How is kraft paper made? If you want to know the answer to this question, here is the detailed process of the new method of manufacturing kraft paper rolls:
Pulping Process
In this pulping process, wooden pulp is washed and screened to get the natural, chemical-free material for kraft paper production. The main purpose of pulping is to collect useful fibers.
Refining
After pulping, it passes through the refining machine to improve the texture of the fibers. It modifies the roughness and durability of the paper.
Forming
When the fibers are refined, the forming process dilutes the material with water. Then this material is spread on the paper machine and prepared to be converted into a sheet.
Pressing
Extra water remains in the forming process. In the pressing process, the sheet passes through the press rolls to remove the extra water to strengthen it. Then, prepare the sheet for the drying process.
Drying
In the drying process, the remaining moisture is removed from the sheet through heated cylinders. It controls the moisture in the paper and improves the durability of the paper.
Finishing
The finishing process handles the size, quality and shape of the paper according to the requirements. It ensures the paper weight and quality.
Traditional Methods Vs. Modern Methods: What Improvements Have Come In The New Method Of Kraft Paper Manufacturing?
Traditional and modern methods have the same manufacturing process. The only difference between them is the use of old and new equipment and techniques in the making of kraft paper material. Here are some improvements in the new manufacturing process:
- Higher pulping efficiency: The modern pulping method controls the temperature and pressure more precisely than the traditional method.
- Lower energy consumption: Modern tools control and recover the heat system better than traditional method.
- Reduced water consumption: Instead of the traditional method, water can be recycled and reused in the modern method.
- Better quality control: The modern method uses an automated monitoring process to control the temperature, moisture and thickness of the paper.
