Dairy-Specific Applications

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.
