6. Frequently Asked Questions (B2B Procurement FAQ)

In-depth technical and commercial answers compiled by packaging engineers for OEM/ODM buyers, brand owners, and co-packers.

What is the Minimum Order Quantity (MOQ) for custom printed wholesale 250ml slim cans?
For plain (bright) unprinted 250ml slim cans, the standard factory MOQ is one 40ft High Cube container (approx. 500,000 to 550,000 pieces depending on pallet stacking density). For custom offset-printed cans featuring up to 8 colors or tactile varnish finishes, the minimum production run starts at 100,000 to 300,000 pieces per artwork design SKU, which accounts for high-speed printing plate setup, ink wash-down, and temperature stabilization on automated decorator lines.
How do I select the right internal lacquer (coating) for my beverage formula?
Internal lacquer choice depends entirely on product chemistry:
Epoxy-Based Coatings: Excellent all-round performance for standard carbonated soft drinks, beers, and non-acidic teas.
BPA-NI (Non-Intent) Acrylic/Polyester Resins: Mandatory for compliance in North America and Western Europe, suitable for craft soda, sparkling water, and energy drinks.
Organosol Coatings: Formulated specifically for high-acidity beverages (pH < 3.0), high ethyl alcohol content (> 12% ABV), or corrosive ingredients such as heavy cider, wine, organic acids, or sulfur-containing mixers.
Can 250ml slim aluminum cans withstand tunnel pasteurization or hot-filling processes?
Yes. 250ml slim cans manufactured from 3104-H19 alloy are engineered to withstand internal pressure build-up during thermal processing. For tunnel pasteurization (common in brewing and cider production), the can base is domed to resist internal pressure spiked up to 6.2 bar at 65°C–70°C. For hot-filling processes (used in fruit juice and RTD tea at 85°C–92°C), liquid nitrogen dosing is recommended prior to seaming to maintain internal positive pressure upon liquid cooling and prevent body panel collapse.
What easy-open lid (end) options pair with 250ml slim cans?
The standard 250ml slim can features a 200 neck diameter (Ø 50mm). It is primarily paired with:
200# SOT (Stay-On Tab): The standard beverage opening mechanism for carbonated soft drinks, beer, and energy drinks.
200# RPT (Resealable Pull Tab): Modern re-closable end design ideal for premium energy shots and functional beverages on-the-go.
Custom Color Tabs & Laser Etching: Colored anodized tabs (red, black, blue, gold) and under-tab promo laser etching for brand engagement campaigns.
What is the typical production and shipping lead time from China factories?
Standard OEM production lead times average 15 to 25 working days following digital artwork proof approval and deposit receipt. Shipping transit times vary by destination port:
US West Coast (Los Angeles/Oakland): 14 to 18 days ocean freight.
US East Coast (New York/Savannah): 28 to 35 days ocean freight.
Main European Ports (Rotterdam/Hamburg): 25 to 32 days ocean freight.
Southeast Asia (Singapore/Port Klang): 7 to 10 days ocean freight.
