Color-coated tinplate combines the corrosion resistance of tin-plated substrate and the decorativeness of color-coating process to provide cost-effective solutions for industrial packaging. The core advantages and typical applications are as follows:

1. Core advantages

Corrosion resistance and rust protection

The tin-plated layer is combined with epoxy/polyester coating, and the salt spray test is over 500 hours, which effectively resists moisture and chemical corrosion. For example, a chemical company uses it to make lubricating oil barrels, which have no rust or leakage in coastal storage environments for 3 years.

High decorativeness and brand empowerment

Supports customized matte, metallic texture and other coating effects, printing adhesion reaches 5B, and is suitable for the outer packaging logo requirements of industrial products.

Easy processing and molding

Excellent ductility (elongation ≥ 20%), can be stamped and curled to make special-shaped containers. A certain auto parts factory uses 0.18mm color-coated tinplate to stamp bolt packaging cylinders, and the production efficiency is increased by 35%.

Environmental protection and economy

The material is 100% recyclable, and the cost is 50% lower than that of stainless steel packaging. A lithium battery company uses it to make transport boxes for electrode materials.

II. Typical application scenarios

Industrial consumables packaging: welding wire barrels, lubricating oil tanks.

Electronic product protection: anti-static turnover boxes for circuit boards.

Building materials transportation: moisture-proof containers for screws/nuts.

Chemical industry: powder coating metal cans.

Color-coated tinplate has become an upgraded option to replace traditional plastic and wooden boxes in the industrial packaging field through the dual optimization of "function + cost".
