　　Does using water-based ink for flexographic printing result in VOC emissions below 0.5g/m? It is far superior to solvent based inks.

　　建立色差管理系统，通过分光光度计控制ΔE值≤2，确保批量产品颜色一致性。

　　Establish a color difference management system and control the Δ E value ≤ 2 through a spectrophotometer to ensure color consistency of batch products.

　　三、检测体系：多维验证保障品质

　　3、 Testing System: Multidimensional Verification to Ensure Quality

　　物理性能测试：

　　Physical performance testing:

　　边压强度（ECT）需达800N/m以上，防止盛装重物时变形泄漏。

　　The edge compression strength (ECT) should be above 800N/m to prevent deformation and leakage when carrying heavy objects.

　　耐温性能测试：-20℃冷冻24小时后，盒体挺度保持率≥85%；100℃热封30分钟无分层。

　　Temperature resistance test: After being frozen at -20 ℃ for 24 hours, the stiffness retention rate of the box body is ≥ 85%; Heat seal at 100 ℃ for 30 minutes without delamination.

　　化学安全检测：

　　Chemical safety testing:

　　总迁移量检测采用4%乙酸模拟液，结果需≤10mg/dm?。

　　The total migration amount is detected using a 4% acetic acid simulation solution, and the result should be ≤ 10mg/dm?.

　　高锰酸钾消耗量控制在5mg/kg以内，避免有机物残留。

　　The consumption of potassium permanganate should be controlled within 5mg/kg to avoid residual organic matter.

　　微生物指标控制：

　　Microbial index control:

　　生产环境执行10万级洁净标准，空气菌落数≤500CFU/m?。

　　The production environment shall comply with the 100000 level cleanliness standard, with an air bacterial count of ≤ 500 CFU/m?.

　　成品需通过大肠杆菌、沙门氏菌等致病菌检测，确保无菌包装。

　　The finished product needs to be tested for pathogenic bacteria such as Escherichia coli and Salmonella to ensure sterile packaging.

　　四、环保认证与追溯机制

　　4、 Environmental certification and traceability mechanism
