Q: Why 0.14mm for beverage ends?
A: 40% thinner vs. standard 0.20mm, reducing material cost while maintaining seal integrity.
Q: Maximum pH for 0.55mm chemical drums?
A: Stable at pH 14 (40% NaOH) with ≤0.001mm/year corrosion rate.
Q: MOQ for custom coatings?
A: 25 tons with SGS corrosion reports (15-day lead time).
Q: Temperature limit for 0.18mm seafood lids?
A: Withstands 105°C sterilization; resistant to -30°C freezing.
Q: Recycling process?
A: Coatings vaporize in EAF (>1,600°C); no de-tinning required.
