After decades of development, the Chinese sanitary napkin industry has formed a market worth billions of yuan, but it is facing an unprecedented crisis of trust in 2025. The industry scandal exposed at the 3.15 Evening Gala is shocking: illegal merchants purchase brand waste for 260 yuan/ton, which is manually sorted and mixed with pollutants such as cigarette butts and masks, and then repackaged to enter the market. What is even more shocking is that there is a widespread problem of shrinking specifications in the products circulating on the market. Some products have a total bacterial count exceeding 12 times the standard and heavy metal content exceeding 8 times the EU standard, but still pass routine testing, exposing serious defects in traditional production processes.
In this context, ultrasonic welding technology, with its revolutionary innovation advantages, is reconstructing the quality standards and technical ethics of the sanitary napkin industry. This breakthrough technology achieves the fusion of material molecular layers through high-frequency vibration, demonstrating five core advantages compared to traditional hot melt adhesive processes:
1、 Molecular level fusion technology
The APSonic welding technology uses 15~40kHz high-frequency mechanical vibration to achieve seamless bonding between non-woven fabric and SAP absorbent resin at the molecular level, greatly improving the bonding strength and completely solving the problems of fracture and displacement caused by traditional processes.
2、 Micron level precision manufacturing
The precision of APSonic welding equipment can reach 5 μ m level, ensuring precise molding of the guide groove and three-dimensional enclosure, improving product absorption efficiency, and achieving medical grade leak prevention performance.
3、 Zero sensitization safety guarantee
Ultrasonic welding sanitary napkins completely eliminate chemical adhesives such as formaldehyde and benzene, eliminating the risk of contact dermatitis caused by adhesive residue at the root.
4、 Green Production System
Ultrasonic welding sanitary napkins combined with biodegradable materials can reduce the amount of scraps produced, achieving a win-win situation of economic and environmental benefits.
The significance of this industrial transformation led by ultrasonic welding technology has gone beyond technological iteration itself. Tens of thousands of comments in the Xiaomi brand review section; Seeking production of sanitary napkins; The voice of users indicates that contemporary consumers are no longer pursuing only basic functions, but also respecting and protecting the right to life and health.
As a technological benchmark in the industry, the APSonic welding system is striving to; Micron level accuracy; Redefine quality standards using '; Zero Defect Commitment; Rebuilding market trust. When every sanitary pad can withstand the most rigorous testing, we will eventually realize that true industrial progress is always built on the cornerstone of technology for the good; The level of civilization in an industry ultimately depends on its deep practice of humanistic care.
