Industry-Leading 400g Packaging Solution

We utilize advanced production lines to manufacture cylindrical tinplate cans that set the global industry standard, specifically designed for a 400g net fill weight. These robust containers are optimized for large-scale, automated fruit and vegetable preservation lines, offering superior physical barrier protection for high-acid ingredients such as peeled, diced, or crushed tomatoes.

Specifications

Capacity: Precisely calibrated for 400g / 400ml net capacity

Can Structure: Three-piece cylindrical construction with welded side seams

Base Material: High-purity electrolytic tinplate with customizable hardness grades

Internal Coating: Double-baked, high-solids organic organosol coating (BPA-NI / BPA-free formulation available)

Top Closure: Rigid, scored Easy-Open End (EOE) with a smooth, safe edge

Thermal Resistance: Engineered to withstand industrial steam sterilization processes exceeding 121°C

Global Certification: Production strictly complies with current FDA and BRCGS standards

Application Advantages

1. High-Performance Acid-Resistant Coating Technology

Processed tomatoes contain natural citric acid, which is highly corrosive to exposed steel. To eliminate the risk of pinhole corrosion or metallic off-flavors, our 400g cans feature a premium, double-baked organic internal coating. This advanced barrier ensures complete isolation, preserving the food's vibrant color, natural flavor, and a shelf life of up to 36 months.

2. Micro-Welded Seams and Liquid Repair Process

The longitudinal can body seam is formed using a high-frequency continuous welding process, immediately followed by the application of a smooth, food-grade liquid coating strip. This seamless reinforcement ensures the container withstands immense internal pressure during hot filling, vacuum sealing, and high-temperature sterilization without structural or micro-leakage.

3. High-Speed ​​Equipment Compatibility

Manufactured with strict tolerances, the can's top and bottom double-seam designs ensure smooth conveyance through automatic depalletizers and high-speed filling lines. Precise curl geometry ensures a perfect double-seam result when used with commercial seaming chucks and rollers, thereby minimizing scrap rates during peak production periods. B2B Procurement Process Overview

• Filling Line Compatibility Assessment: Verification of product viscosity and target headspace requirements to ensure optimal matching of seaming parameters.

• Pre-press Proofing: Please submit vector artwork in AI or PDF format. Our technicians map the design onto a flat layout template to ensure precise alignment prior to printing.

• Physical Prototype Testing: We supply unprinted (plain) can samples directly to your QC laboratory to verify double-seam tolerances and pressure resistance limits.

• Bulk Delivery and Inspection: Production utilizes automated lines equipped with high-speed optical inspection sensors to reject products with structural defects prior to packaging.

Frequently Asked Questions (FAQ)

Q1: Is this 400g empty can suitable for automated retail labeling lines?

A1: Yes. Its straight-walled cylindrical body provides a smooth, uniform surface free of visual defects, offering excellent compatibility with high-speed cold-glue or hot-melt labeling machines.

Q2: Do you offer internal coating options that meet strict EU and US environmental standards?

A2: Certainly. We offer advanced BPA-NI (BPA-Non-Intentionally Added) and polyester-based internal coating solutions that fully comply with EFSA and US FDA regulations for materials in direct contact with food.

Q3: What is the Minimum Order Quantity (MOQ) for this standard 400g specification?

A3: As this is an industry-standard specification in continuous production, we offer flexible MOQ options: 50,000 units for custom printed designs, with lower MOQs available for plain silver or gold cans.

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

A4: To ensure the products arrive in perfect condition, the empty cans are automatically nested and stacked onto 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 sea transport.
