3-Piece 400g Empty Tin Cans for Wet Cat Food (Sauce & Gravy Line Compatibility)

For cat food formulations with high liquid content—such as chunks in gravy, cuts in rich sauce, or stews—packaging in standard metal containers presents significant chemical compatibility challenges. Without proper mitigation, the interaction between high moisture levels and amino acids in animal proteins can accelerate sulphide staining (sulphide spots) and microscopic internal corrosion.

Our 400g empty cat food cans resolve this industry challenge through advanced materials engineering. We utilise a multi-layer, high-adhesion internal coating system (featuring 100% BPA-free organosol or modified epoxy-phenolic formulations). This protective layer effectively isolates the steel substrate from gravy or acidic sauces, thereby completely preventing internal staining, oxidation, and product discolouration throughout a commercial shelf life of several years.

Part II: Technical Specifications and Tolerance Parameters

To ensure seamless integration into high-speed automated filling lines (such as Zacmi or FMC seaming systems), our production lines strictly adhere to international dimensional tolerance standards.

• Nominal Capacity/Size: 400g — Standard international diameters (typically 73mm/300# or 307#, depending on height specifications).

• Substrate: Premium T3/T4 grade Double-Reduced (DR) or Single-Reduced (SR) Electrolytic Tinplate (ETP).

• Welding Technology: High-precision electronic side-seam welding, supplemented by post-weld nitrogen shielding to eliminate structural weak points.

• Thermal Deformation Metrics: 100% resistant to high-temperature sterilisation. Proven to withstand temperatures up to 120°C (250°F) under rigorous overpressure conditions without deformation of the can body walls, buckling, or distortion of the double seam (flange). Part 3: Superior High-Speed ​​Seaming Performance

Seaming jams are a primary cause of production downtime. Our empty cans feature precision-formed flange geometry, ensuring smooth, trouble-free double-seaming operations with compatible Easy-Open Ends (EOE) or standard bottom ends. Every batch undergoes comprehensive quality testing:

1. Fully automated, in-line 100% light-transmission inspection: Detects and eliminates microscopic pinholes invisible to the naked eye.

2. Internal coating continuity test (porosity check): Ensures no exposed metal comes into contact with meat juices or sauces.

3. Axial load deformation resistance test: Guarantees safe palletising and stacking during ocean freight transport to major markets such as Southeast Asia (Indonesia/Thailand), Europe, and North America.
