❓ Frequently Asked Questions (FAQ)

Q1: Can these unprinted silver cans be used with automatic wrap-around labeling machines?

A: Absolutely. These cans are designed for automated post-filling labeling lines. The seamless, rib-free exterior ensures that rubber rollers and hot-melt applicators can apply paper or BOPP film wrap-around labels with high speed and strong adhesion.

Q2: Do these plain cans offer rust protection during the wet sterilization and cooling stages?

A: Yes. Although the can bodies are unprinted, the exterior is coated with a high-quality, clear, food-grade lacquer. This protective coating is applied to the steel surface via a high-temperature baking process; it is designed to prevent oxidation caused by moisture, thereby ensuring that no rust spots form on the can surface during high-temperature, high-pressure sterilization (autoclaving) at 121°C.

Q3: What is the typical factory lead time for bulk orders of unprinted, plain empty cans?

A: Since plain silver or gold cans do not require the color-matching steps associated with custom printing, we maintain ample stock of standard sizes (such as 73mm and 83mm diameters). Orders for unprinted cans can typically be shipped within 7 to 14 days, significantly shortening your procurement cycle compared to custom-printed batches.
