                        \n
                      1. Safety warnings and compliance (GHS Standards): Under the Globally Harmonized System of Classification and Labelling of Chemicals (GHS), labels must clearly identify the physical hazards (e.g., flammability, explosiveness), health hazards (e.g., toxicity, corrosiveness), and environmental hazards of chemicals using pictograms, codes, and text, ensuring that workers are properly aware of potential risks.<\/span><\/li>\n
                      2. Logistics and tracking: Labels often include chemical information, batch numbers, manufacturers, barcodes or QR codes for identification, transportation, and traceability. They need to be corrosion-resistant and abrasion-resistant to withstand harsh environments.<\/span><\/li>\n
                      3. Emergency response instructions: Labels include specific product safety instructions, first-aid measures, and the manufacturer’s emergency contact number to facilitate prompt action in the event of spills or accidental injuries.<\/span><\/li>\n
                      4. Routine chemical management: Chemical containers used in warehouses and laboratories help personnel identify materials, prevent misuse, and ensure compliant storage.<\/span><\/li>\n<\/ol>\n

                        Label materials and production: Considering the properties of chemicals, chemical labels need to have high durability (solvent resistance, resistance to extreme temperatures). They are often made of synthetic paper (such as YUPO) or polyester film, combined with high-damping ribbon printing to ensure integrity on chemical containers.<\/span><\/p>","protected":false},"excerpt":{"rendered":"
