Recently, the occupational standard "Hot Melt Adhesives for Sanitary Products" (HG/T 3948-2025), approved and issued by the Ministry of Industry and Information Technology, was officially implemented on March 1, 2026. Jahao (Taicang) New Material Co., Ltd. (Jiangsu Jahao Hot Melt Adhesive Co., Ltd.), as one of the main drafting units, was deeply involved in the formulation of this standard. This not only represents the industry's high recognition of Jahao's technical capabilities but is also a significant achievement of the company's years of dedication to the hot melt adhesive field and its commitment to technological innovation.
Standard Upgrade, Leading High-Quality Industry Development
The HG/T 3948-2025 standard is the first comprehensive revision of the 2007 version, achieving a leap from "conformity assessment" to "quality enhancement." The new standard introduces important updates in several aspects:
· Significant Technical Breakthroughs
The standard adds an odor detection and evaluation method, establishing a scientific and standardized odor assessment system to address odor issues in sanitary products at the source and improve consumer experience. Simultaneously, the standard sets limits for harmful substances, further refining raw material admittance criterion and building a defense line for the overall safety performance of sanitary products.
Jahao Hot Melt Adhesive has a professionally trained odor evaluation panel for odor assessment. Combined with quantitative analysis from experimental instruments like GC-MS (Gas Chromatography-Mass Spectrometry) and TGA (Thermogravimetric Analysis), it ensures that Jahao's hot melt adhesives for disposable sanitary products meet the extremely low odor requirements of high-end customers.

· Expanded Scope of Application
The standard name has been expanded from the original "Hot Melt Adhesive for Positioning of Sanitary Napkins and Panty Liners" to "Hot Melt Adhesives for Sanitary Products," making its application scope broader.
· Optimized Testing Methods
The standard improves the T-peel strength test method, making adhesive performance test results more accurate and scientific, providing authoritative basis for enterprise production control and product quality traceability.
Responsibility and Commitment, Creating the Future Together
Being able to participate in the formulation of an industry standard is an honor and, more importantly, a responsibility. Leading the development of this industry standard is not only a reflection of the company's technical strength but also a concrete action by Jahao, as an industry leader, to actively fulfill social responsibility and promote the standardized development of the entire industry.
Standard Leads, Quality Protects. Jahao Hot Melt Adhesive, Bonding the World, Connecting the Future!
