FAQ
Q: Why ETP over aluminum for milk powder?
A: 30% better moisture barrier and magnetic separation in recycling streams.
Q: Minimum coating for iron contamination prevention?
A: 2.8/2.8 g/m² blocks metal migration (tested per ISO 4531).
Q: Compatibility with nitrogen flushing?
A: Yes – maintains >99% gas retention after 6 months.
Q: Lead time for custom-printed sheets?
A: 25 days including microbial contamination testing.
Q: Temperature tolerance during transport?
A: -40°C to 60°C without embrittlement or condensation.
