Product Description
Premium Food-Grade Electrolytic Tin Plate for Hygroscopic Products
QuanJiang's Prime Electrolytic Tin Plate (ETP) delivers exceptional performance for milk powder, protein supplements, and infant nutrition packaging. This GB-certified material provides superior oxygen and moisture barrier properties with ultra-clean surfaces to prevent nutrient degradation and contamination.
Critical Performance Features
- Absolute Moisture Barrier: Tin-chromium matrix blocks H₂O ingress (<0.1g/m²/24hr) and maintains <3% RH internal humidity for 24+ months
- Nutrient Preservation System: Prevents lipid oxidation (peroxide value <1 meq/kg) and blocks UV light transmission (99.8% opacity)
- Infant-Safety Certified: 0 BPA, phthalates, or heavy metals (Pb/Cd <0.01ppm) - exceeds GB 4806.9-2016 food contact standards
- Advanced Processing Ready: Laser-weldable seams (0.2mm precision) with high-speed stamping compatibility (1,200 cans/min)
