1. Wood pulp qualityWood pulp is one of the main raw materials for making brown kraft paper. Its quality has a crucial impact on the tear resistance of paper. The quality of wood pulp determines the fiber structure, strength and durability of paper. Different types of wood pulp (such as softwood pulp, broadleaf pulp, etc.) will affect the different properties of paper. Softwood pulp (softwood pulp) and tear resistanceSoftwood pulp comes from coniferous trees such as pine and fir. Its fibers are long and flexible and can provide high tensile strength. The longer fibers in softwood pulp can form a stronger fiber web, thereby increasing the tear resistance of paper. Due to the length and strength of these fibers, brown kraft paper produced from softwood pulp usually exhibits better tear resistance and durability. Broadleaf pulp (hardwood pulp) and tear resistanceBroadleaf pulp comes from broadleaf trees such as oak and birch. These trees have shorter fibers but higher toughness. Hardwood pulp paper has a smooth surface and good water absorption, but its tear resistance is usually not as good as softwood pulp paper. Hardwood pulp is usually used to improve the softness and printability of paper, but if strong tear resistance is required, hardwood pulp alone may not be as effective as softwood pulp. Fiber length and quality of wood pulpIn addition to the source of wood pulp, the fiber length and quality of wood pulp are also key factors affecting the strength of paper. Longer fibers can interweave with each other to form a tighter network structure, improving the overall strength and tear resistance of paper. High-quality wood pulp usually has higher fiber quality and longer fiber length, which allows the paper to withstand more pressure and is not easy to be torn. 2. Use of recycled pulpRecycled pulp is another important raw material for brown kraft paper. Recycled pulp is usually made from recycled materials such as waste paper and cardboard through processes such as deinking and washing. Recycled pulp has significant advantages in environmental protection and reducing production costs, but its quality may also affect the tear resistance of paper. Quality differences of recycled pulpThe quality of recycled pulp is closely related to its source and processing process. Recycled pulp from high-quality raw materials (such as waste cartons, office paper, etc.) usually has good fiber quality, and the kraft paper made from it can also maintain strong tear resistance. Waste paper from poor sources (such as ink printing paper, paper with chemical coatings, etc.) may affect the quality of the pulp, resulting in poor strength and low tear resistance of the brown kraft paper. Recycled pulp and tear resistanceRecycled pulp usually contains shorter fibers, and its tear resistance is usually not as good as wood pulp. The fibers of recycled pulp will gradually become shorter and more fragile during repeated use and processing, resulting in a decrease in the overall structural strength of the paper. Nevertheless, by optimizing the processing process of recycled pulp and reducing impurities and foreign matter in the pulp, the strength of the paper can still be improved to a certain extent. Use of additivesDuring the manufacturing process, manufacturers may add some chemical additives to improve the fiber quality and strength of recycled pulp. These additives include reinforcing agents, cross-linking agents, flexibilizers, etc., which can improve the structure of recycled pulp and increase the bonding force between fibers, thereby improving the tear resistance of paper. The use of additives also needs to be cautious, because excessive use may affect the environmental performance of paper. 3. Raw material processing technologyThe raw material processing technology is another important factor affecting the tear resistance of paper. In the paper production process, wood pulp and recycled pulp will go through a certain processing process, including cooking, bleaching, beating, etc. These process steps directly affect the fiber structure and strength of the paper. Pulping processPulping is the process of mechanically treating the fibers in wood pulp or recycled pulp. Through beating, the fibers in the pulp will be further dispersed and elongated to form a more uniform fiber network. In this process, the length and shape of the fibers will affect the tear resistance of the paper. Proper beating can increase the strength of the paper and improve its tear resistance. Forming and pressingDuring the forming process of paper, the pulp will be evenly coated on the screen to form a thin paper layer. During the pressing process after forming, the paper will experience high pressure, which helps to make the fibers more closely bonded, thereby improving the strength of the paper. The pressure and time of pressing also directly affect the tear resistance of the paper. Improper pressing may result in a paper surface that is too tight, making it brittle and prone to tearing. Bleaching and decontaminationBleaching is the process used to remove the natural pigments in the wood pulp to make the paper whiter. While brown kraft paper is not typically bleached, even unbleached wood pulp may go through some decontamination process to remove unwanted impurities and resins. This helps improve the uniformity and strength of the paper, making it stronger and more resistant to tearing.

1. Scientific planning of stacking methodsThe stacking method is one of the key factors affecting the quality of coated kraft paperboard. Reasonable stacking can not only effectively prevent the deformation and damage of the paperboard, but also improve the utilization rate of storage space. Stack flat and avoid foldingCoated kraft paperboard should be stacked as flat as possible to avoid creases and damage caused by folding or overlapping. When stacking, ensure that there is a certain gap between the paperboards to avoid keeping the same bending position for a long time to reduce the occurrence of creases. At the same time, the stacking height should be moderate to avoid excessive height causing the bottom paperboard to be compressed and deformed. Classified stacking and clear labelingFor coated kraft paperboards of different specifications, thicknesses and uses, they should be classified and stacked, and clearly labeled. This helps to quickly identify the required paperboard, reduce the time of searching, and avoid confusion and damage between different specifications of paperboards. Use pallets or shelvesWhen stacking coated kraft paperboard, pallets or shelves can be used to support the paperboard to reduce direct contact with the ground. This not only prevents the influence of ground moisture on the cardboard, but also improves the stability and safety of stacking. 2. Careful construction of storage environmentThe storage environment is crucial to the quality of coated kraft paperboard. A dry, ventilated and temperature-appropriate storage environment can effectively extend the service life of the paperboard. Keep dry and avoid moistureCoated kraft paperboard is susceptible to moisture, so the storage environment should be kept dry. You can choose to install a dehumidifier or place a desiccant in the warehouse to reduce humidity. At the same time, the walls, floors and ceilings of the warehouse should be checked regularly for leaks, and repaired in time to prevent moisture from invading. Good ventilation and avoid confinementThe warehouse should maintain good ventilation to avoid air stagnation caused by a confined environment. You can open windows for ventilation regularly, or use equipment such as exhaust fans to accelerate air circulation. This helps to reduce the temperature and humidity in the warehouse and keep the cardboard dry and stable. Appropriate temperature, avoid extremesThe temperature of the storage environment should be kept within a certain range to avoid overheating or overcooling. Generally speaking, the temperature between 15~25℃ is more suitable. Too high a temperature may cause the strength of the cardboard to decrease, while too low a temperature may make the cardboard brittle. Therefore, the temperature control equipment of the warehouse should be adjusted according to the actual situation to ensure that the temperature is appropriate. 3. Careful implementation of maintenance measuresIn addition to the stacking method and storage environment, meticulous maintenance measures are also an important part of ensuring the quality of coated kraft paperboard. Regular cleaning and stain removalDuring storage, coated kraft paperboard may be stained with dust, oil and other stains. Therefore, the surface of the paperboard should be gently wiped with a soft brush or dry cloth regularly to remove stains and dust. Avoid using a wet cloth or detergent containing chemicals for cleaning to avoid damage to the paperboard. Anti-insect and anti-moth, protect the paperboardCoated kraft paperboard is an edible object for insects, so measures should be taken to prevent pests. An appropriate amount of insect repellent or mothballs and other items can be placed in the warehouse to repel insects. At the same time, the warehouse should be checked regularly for signs of pests, and timely measures should be taken to deal with them. Regular inspection and timely treatmentRegular inspection of stored coated kraft paperboard is an important measure to ensure quality. A comprehensive inspection can be carried out monthly or quarterly, including the appearance, strength, printing adaptability and other aspects of the cardboard. If the cardboard is found to be deformed, moldy, discolored or damaged, timely measures should be taken to deal with it, such as replacing the damaged cardboard, adjusting the storage environment, etc. Avoid placing heavy objects on the cardboard to protect the integrity of the cardboardDuring storage, avoid placing heavy objects directly on the coated kraft cardboard to avoid crushing or deformation. If you need to use shelves or pallets to support the cardboard, ensure that the load-bearing capacity of the shelves or pallets is sufficient, and check their stability and safety regularly.
