FAQ
Q: Why choose 2.8 coating over 5.6 for tomato cans?
A: 2.8g/m² balances cost/performance for pH>3.5; 5.6g/m² recommended for pH<3.0 products.
Q: Maximum width for litho printing?
A: 1,029mm with ±2mm tolerance – supports 8-color presses.
Q: Compliance for EU baby food?
A: Exceeds EC 10/2011 – tin migration <0.1 mg/kg.
Q: Lead time for custom temper orders?
A: 35 days including hardness certification reports.
Q: Recycling compatibility?
A: Directly feeds steel EAF streams – no de-tinning required.
