Stainless steel milk can manufacturers

For food safety and durability, you must prioritize Food Grade Stainless Steel (SUS304 or SUS316). SUS304 is the industry standard for corrosion resistance, while SUS316 offers superior protection against acidic liquids or saline environments. Ensure the thickness is at least 0.8mm to 1.2mm to prevent denting during transport, and verify that the interior has a mirror-polished finish (Ra < 0.4μm) to prevent bacterial buildup and facilitate easy cleaning.

A professional milk can should feature a heavy-duty silicone gasket that is FDA or LFGB certified. Look for a locking-ring mechanism or three-point toggle latches that provide airtight compression. The lid design should be a recessed or 'plug' style to ensure that even if the can is tipped, the liquid remains contained without contaminating the seal area.

Buyers must ensure the products comply with Food Contact Materials (FCM) regulations. For the US market, FDA 21 CFR compliance is required; for the EU, Regulation (EC) No 1935/2004 is the benchmark. Additionally, look for ISO 9001 certification for the manufacturer to ensure consistent production quality and NSF certification if the product is intended for commercial food service.

Check for seamless welding (Argon Arc Welding) at the base and handles to prevent leaks and handle failure. The bottom should be reinforced with a double-layer or a thickened skirt to withstand dragging and impact. Handles should be ergonomically designed and spot-welded at multiple points to support a full load, which can exceed 50kg for larger 50L cans.

Request a Material Test Report (MTR) or a Third-Party Inspection (TPI) such as SGS or Intertek before shipment. You can also ask the supplier to perform a Stainless Steel Moly Drop Test during a live video call. For secure transactions, use Made-in-China.com's secured payment services to ensure funds are only released after quality verification.

Stainless steel milk cans are 'light cargo' that occupies significant volume. Negotiate for nested packaging (smaller cans placed inside larger ones) to optimize container utilization. For large orders, FOB (Free On Board) is recommended so you can control the freight forwarder and choose Sea Freight (LCL or FCL), which is significantly more cost-effective than air for high-volume metal goods.

Most top-tier suppliers on Made-in-China.com offer OEM/ODM services. When negotiating, specify your Laser Etched Logo requirements and custom packaging early. Aim for a 30% deposit and 70% balance payment against the Bill of Lading (B/L). For first-time orders, request a pre-production sample to verify the thickness and seal tension before the full production run begins.
