OEM Large Wet Wipe Factory

During the production process, how to ensure the dimensional stability and uniformity of wet wipes, especially for large-sized wet wipes?

Material selection and pretreatment
In terms of material selection, Wanfang Paper insists on using high-quality fiber raw materials, such as specially treated virgin wood pulp or bamboo pulp. These materials not only have excellent water absorption, softness and strength, but also effectively reduce the risk of fuzzing and breakage, laying a solid foundation for the dimensional stability of wet wipes. We are well aware that the length, fineness and chemical properties of the fiber directly affect the strength and dimensional stability of the wet wipes. Therefore, we strictly screen and test the raw materials to ensure that each batch of materials meets our high standards.
In the material pretreatment stage, we use advanced pulp preparation technology to optimize the dispersion state and interweaving ability of the fibers by precisely controlling the concentration, temperature and proportion of chemical additives of the pulp, further enhancing the structural stability of the flushable wet wipes substrate. In addition, we have also introduced ultrasonic processing technology, using high-frequency vibration to promote close bonding between fibers, effectively reducing the deformation and dimensional changes of wet wipes during use.
Manufacturing process and equipment precision
During the production process, Wanfang Paper uses a highly automated massive wet wipes production line equipped with internationally leading forming, embossing, cutting and packaging equipment. These equipment not only improve production efficiency, but more importantly, they have a high-precision control system that can accurately control the forming size, thickness and weight of wet wipes, ensuring the dimensional stability and uniformity of large wet wipes.
Especially in the cutting process of wet wipes, we use laser cutting technology. Compared with traditional mechanical cutting, laser cutting has higher precision and flexibility, which can ensure that the edges of wet wipes are smooth and flawless, while reducing the problem of inconsistent sizes caused by cutting errors. In addition, we also reduce heat accumulation during cutting by continuously optimizing the cutting path and speed, avoid material shrinkage caused by local overheating, and further improve the dimensional stability of wet wipes.
Quality control system
Wanfang Paper has established a complete quality control system, with strict quality inspection points at every link from raw material storage to finished product delivery. For large-sized multiuse wet wipes, we pay special attention to the detection of their dimensional stability and uniformity. We use advanced measuring instruments, such as high-precision vernier calipers, electronic scales and image measurement systems, to randomly sample and test the length, width, thickness and weight of wet wipes to ensure that each batch of products meets the design specifications.
We have also established a data analysis system to record and statistically analyze the test results in real time, promptly detect abnormal fluctuations in the production process, and take corrective measures to ensure the stability and controllability of the production process. In addition, we also regularly maintain and calibrate production equipment to ensure that the equipment accuracy is always in the best condition, providing a solid guarantee for the dimensional stability and uniformity of multiuse wet wipes.
Environmental protection and sustainable development
While pursuing the dimensional stability and uniformity of flushable wet wipes, Wanfang Paper also attaches great importance to environmental protection and sustainable development. We use environmentally friendly wet strength agents and softeners, which not only meet international safety standards, but also reduce the negative impact on the environment during biodegradation. In addition, the concepts of water conservation, energy conservation and resource recycling are integrated into our production process, such as using a closed circulating water system to reduce water consumption, using waste heat recovery technology to reduce energy consumption, and reducing raw material waste through waste paper recycling.
Special design for women and children
In view of the more delicate and sensitive skin of women and children, Wanfang Paper pays more attention to details in the research and development and production of wet wipes. We have specially developed wet wipes containing natural plant essences and moisturizing factors. These ingredients can not only effectively protect the skin, but also enhance the softness and comfort of wet wipes. At the same time, we use advanced non-woven fabric technology to make massive wet wipes tougher and less prone to damage. Even when wiping vigorously, they can maintain stable size, providing women and children with a safer and more comfortable use experience.
