ISO 14064-1, ISO 14068-1, Carbon Neutrality certificates of Jaour Near-Zero Carbon Emission Plant — Key Concepts A Near-Zero Carbon Emission Plant​ (近零碳排放工厂) refers to a manufacturing facility that has reduced its net carbon dioxide (CO₂) and other greenhouse gas emissions​ to an extremely low level — approaching, but not necessarily absolute, zero — through a combination of energy efficiency, renewable energy adoption, electrification, carbon capture, and verified carbon offsetting. Core Definition of Near-zero Plant In essence, a near-zero carbon plant achieves a state where: Direct Emissions + Indirect Emissions − Reductions via Offsets ≈ Near Zero Figure 3. Definition of Near-zero Carbon Emission Plant This prestigious recognition underscores our unwavering commitment to sustainable development, environmental stewardship, and the global transition toward a low-carbon economy. The government’s disclosure of the certificate further validates our transparent approach to environmental reporting. As China accelerates its “dual carbon” goals (peak carbon by 2030, carbon neutrality by 2060), our Taicang factory stands as a replicable model to closely follow China’s firm plan of carbon neutralization. Looking ahead, JAOUR will continue to invest in innovative decarbonization solutions, collaborate with supply chain partners, and share best practices with the broader industry. We invite customers, investors, and stakeholders to join us on this journey toward a cleaner, greener future. Better bonding, better life!

In the push toward zero-waste packaging, few innovations have reshaped the labelling world as quietly—and as decisively—as linerless labels.  EU PPWR regulation on packaging materials   By eliminating the silicone-coated backing paper that traditional self-adhesive labels depend on, linerless technology cuts material consumption, reduces transport weight, and removes an entire waste stream from production lines and packing stations alike.  The comparison of the structures between a typical label and a linerless label But this elegant simplification comes at a cost: it places extraordinary demands on the one component that has to do double duty—the hot melt pressure sensitive adhesive (HMPSA). What Makes an HMPSA "Linerless-Grade"? A standard HMPSA for conventional labels is formulated to bond well to a substrate and release cleanly from a liner. A linerless-grade HMPSA must satisfy a far stricter set of criteria simultaneously: 1. High Tack and High Shear Resistance on UV Silicone Release The adhesive must grip the end-use substrate firmly—even at low temperatures in chilled or refrigerated environments—while maintaining sufficient cohesion to avoid stringing, oozing, or leaving residue on printer platen rollers.   2. Resistance to Edge Bleed and Stacking Ooze Because there is no liner, the adhesive is exposed at the edges of the roll. Under the pressure of stacking and the heat inside a shipping container (which can reach 60°C), a soft conventional HMPSA becomes fluid and seeps out—a defect known as edge bleed. Linerless-grade adhesives are formulated with enhanced softening points and higher cohesion​ to remain dimensionally stable in transit.   3. Narrow Melting Window and Thermal Printer Compatibility During printing, the adhesive passes directly against a thermal printhead operating well above 70°C. The adhesive must soften only slightly, never melt or flow, or it will accumulate on the guillotine blade, smear the platen roller, and force frequent shutdown for cleaning. A narrow melting range is therefore essential—the adhesive stays solid enough to avoid deposition, yet tacky enough to perform on the substrate.   4. Low Coating Weight Without Performance Loss Linerless applications can drive coat weights down to 15 gsm​ while still meeting end-use performance, delivering meaningful energy savings in the coating process and maximizing the number of labels per roll. Achieving this requires an HMPSA with high cohesive strength and efficient wetting capability at minimal film thickness.   5. Excellent Die-Cut and Converting Properties The adhesive must cut cleanly under high-speed guillotine or rotary die-cutting without stringing, smearing, or building up on blades—directly reducing production downtime.   Jaour’s Solutions Jaour has been deeply involved in the R&D and production of hot melt adhesives for 20 years. Based on a thorough understanding of the entire linerless label ecosystem — including materials, coating, and labeling — it has developed its own solutions to address all your concerns.

  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. Fig. GC-MS, TGA-IR, and odor assessment certificate  · 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.
