A 425g packaging solution designed specifically for heavy-bodied condiments—our facilities manufacture thick-walled, cylindrical tinplate cans tailored for a 425g (net weight) fill. Engineered to meet the rigorous preservation standards required for industrial fermented food products, this series features advanced internal barrier properties, making it ideal for high-density, high-viscosity sauces such as soybean paste, miso, and thick chili pastes.

Technical Specifications:

Target Capacity: Precisely sized for a 425g (15 oz) net weight condiment fill;

Can Structure: Three-piece, side-seam welded cylindrical construction;

Base Material Grade: High-hardness, single-reduced electrolytic tinplate (MR grade);

Internal Treatment: Abrasion-resistant, high-salinity tolerant gold phenolic coating (BPA-free);

Closure System: Full-aperture Easy-Open End (EOE) with score line;

Thermal Processing: Tested for structural stability under pressurized conditions at 121°C;

Global Standards: Strict compliance with current FDA, BRCGS, and ISO standards.

Application Advantages:

1. Abrasion-resistant internal protection against high salinity—Fermented sauces contain active organic acids and high concentrations of sodium salts that can easily corrode standard metals. To prevent chemical erosion, our 425g sauce cans utilize an advanced, dual-cured, abrasion-resistant coating. This smooth internal barrier effectively blocks corrosive salt ions, ensuring the product retains its authentic flavor throughout a long shelf life.

2. Uniform seam geometry optimized for viscous sauce filling—Thick sauces are typically pumped into containers at high pressure using commercial automatic filling nozzles. Our empty tinplate cans offer superior structural rigidity and a precision-engineered top seam. This geometric accuracy ensures smooth operation on heavy-duty industrial volumetric filling lines, preventing spillage or deformation of the can opening.

3. High-stress resistant structural welds ensuring sterilization safety—Because high-density sauces slow the rate of heat penetration, the cans require stable, extended heating cycles to achieve thorough sterilization. The longitudinal seam of the can body is formed using a high-frequency straight-seam welding process, supplemented by an in-line liquid resin stripe repair. This product offers superior sealing reliability, ensuring no cracking or swelling occurs during industrial steam retort processing.

FAQ

Q1: Can the internal coating prevent viscous sauces from sticking to the metal can walls?

A1: Yes. Our gold phenolic internal coating is available with optional release and lubricating additives. This specialized technology significantly reduces surface friction, allowing thick bean paste to slide out smoothly.

Q2: Do your internal coatings comply with global environmental and chemical regulations?

A3: Yes, fully. We offer advanced "BPA-NI" (BPA-Non-Intentionally Added) internal coating solutions that fully comply with current US FDA and EFSA standards for direct food-contact packaging.

Q3: What are the standard lead times and Minimum Order Quantities (MOQ) for custom-printed sauce cans?

A3: The standard production lead time is 25 to 30 days after design approval. The MOQ for custom full-color offset-printed products is 50,000 units; however, MOQs are more flexible for plain cans with gold or silver interiors.

Q4: How are empty cans stacked to prevent damage during long-distance ocean shipping?

A4: To ensure safe delivery, empty cans are automatically nested and stacked on heavy-duty, fumigation-free pallets. Corrugated protective sheets are placed between layers, the load is securely strapped with high-strength banding, and the entire unit is wrapped in heat-shrink film to protect against moisture during ocean transit.
