常见问题
What is the difference between electrolytic tinplate and regular tinplate?
Electrolytic tinplate has a thinner, more uniform tin coating applied through electroplating, while regular tinplate may use hot-dipping. This makes electrolytic tinplate better for precise forming and corrosion resistance in easy open caps.
Can electrolytic tinplate easy open caps be used for acidic foods?
Yes, the tin coating acts as a barrier against acids, preventing rust and contamination. However, for highly acidic foods, additional lacquer lining is often applied to extend shelf life.
How do I ensure a proper seal when using these caps?
Proper sealing requires matching the cap size to the can opening and using a suitable seaming machine. Always follow the manufacturer's specifications for pressure and temperature during sealing.
