Choosing empty food cans dictates production efficiency. Flawed specifications cause line jams and bloat costs. Smart buyers evaluate metal grades, BPA-NI lining integrity, and dimensional tolerances. Dialing in these specs transforms bulk purchasing into predictable clockwork.
Key Points for Empty Food Cans
➔ Selezione dei materiali: Scegliere stagno, acciaio inossidabile, or composite based on acid resistance, Double-Reduced (DR) forza, e riciclabilità.
➔ Dimensional Fit: Match can diameter, altezza, and wall thickness to fill volumes for precise seaming and BOV compatibility.
➔ Trattamento della superficie: Utilizzare BPA-IN (Non intenzione) internal lacquers and zero-VOC UV-curable inks to safeguard contents and branding.
➔ Garanzia di qualità: Mandate Helium Leak testing and verify FDA compliance to guarantee safe high-volume production.
