Premium Packaging Solution for 425g Legume Products—Our manufacturing facility supplies high-performance empty metal cans optimized for 425g (net weight) products. Designed to streamline commercial vegetable processing, these wide-diameter containers provide a robust physical barrier tailored to the specific storage requirements of low-acid, high-salinity products such as green beans, peas, and mixed bean medleys in brine.

Target Capacity: Precisely calibrated for 425g (compliant with the industry-standard 15 oz capacity)

Can Structure: Three-piece welded cylindrical body with rounded, double-seamed edges

Base Material: Low-carbon chromium-coated steel / Electrolytic tinplate

Internal Coating: Salt-resistant epoxy-phenolic or organosol coating (BPA-NI / BPA-free)

Closure Design: Large-aperture aluminum ring-pull lid / Safe easy-open end

Sterilization Tolerance: Withstands pressurized steam sterilization processes up to 121°C

Compliance: Fully compliant with FDA, BRCGS, and ISO global standards

Application Advantages

1. Specialized Salt-Resistant Internal Barrier: Low-acid foods in brine (such as cut green beans) present unique corrosion challenges. Our 400ml series containers feature a premium epoxy-phenolic protective coating. This chemically resistant barrier effectively blocks sodium ion penetration, preventing internal rusting, discoloration, or flavor degradation over a long shelf life.

2. Reinforced Side Seam for High-Pressure Sterilization: Unlike acidic foods, low-acid vegetables require longer, high-temperature heating processes to ensure food safety. Our can bodies utilize advanced high-frequency induction welding for the longitudinal seam, ensuring the container maintains a complete vacuum and hermetic seal under extreme industrial sterilization pressures, without swelling or micro-cracking.

3. Optimized Circumferential Rib Design for Enhanced Stacking Stability: The exterior can wall features a precision-engineered design incorporating micro-ribs and horizontal circumferential reinforcing ribs. This geometric reinforcement design significantly enhances the container's axial strength and resistance to vertical compression, effectively preventing defects such as denting or sidewall collapse (paneling) that can occur during automated bulk palletizing and high-density ocean shipping.

Procurement Process Overview

Formulation Calibration: Please provide our technical department with the salinity and pH values ​​of your brine solution so we can match the optimal internal coating thickness.

Pre-press Artwork Layout: Please submit vector artwork in AI or PDF format; our design lab will generate a 3D digital flat-pattern proof for your branding approval.

Mechanical Double-Seaming Test: We will deliver unprinted can bodies directly to your production facility to test seaming roll alignment and double-seam tolerance fit.

In-line Quality Manufacturing: Mass production takes place on fully automated lines equipped with high-speed electromagnetic sensors to ensure the absence of physical or structural leaks.

FAQ

Q1: Can these 425g empty cans be used on existing high-speed vegetable filling lines?

A1: Yes. These containers are manufactured in strict accordance with international dimensional standards, ensuring seamless compatibility with standard commercial canning equipment during depalletizing, washing, filling, and double-seaming operations.

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

A2: Yes, fully. We offer advanced "BPA-Non-Intentionally Added" (BPA-NI) internal coating solutions that fully comply with current US FDA and European Food Safety Authority (EFSA) standards for direct food-contact packaging.

Q3: What are the standard lead time and Minimum Order Quantity (MOQ) for custom-printed green bean cans?

A3: The standard production cycle is 25 to 30 days after design approval. The MOQ for custom full-color offset-printed products is 50,000 units; however, more flexible MOQs are available if you choose plain (gold/silver) can bodies.

Q4: How are the empty cans packaged to prevent moisture damage during ocean shipping?

A4: To ensure the products arrive in perfect condition, the empty cans are securely stacked in layers on heavy-duty pallets, with moisture-absorbing cardboard separators placed between the layers and heavy-duty strapping used for fastening; finally, the entire unit is wrapped in UV-resistant industrial stretch film to protect against marine moisture.
