MR Grade Electrolytic Tin Plate Sheets & Coils with Matte Finish
for Can Manufacturing
Product Description
Electrolytic Tin Plate (ETP), commonly designated as SPTE, is a
premium cold-rolled steel substrate electrolytically coated with a
fine layer of tin. This specific product line utilizes high-purity
MR grade steel, renowned for its excellent formability and
consistent quality, making it ideal for demanding metal packaging.
The material is further enhanced with a Matte Finish surface, which
provides a uniform, non-reflective aesthetic and superior paint or
ink adhesion. Available in critical tempers like T4CA and T5CA,
this tinplate is engineered for deep-drawing processes required to
produce aerosol cans, food cans (for tuna, sardines, vegetables),
paint containers, and various ends. Offered in both coil and sheet
formats, it serves as a versatile and reliable foundation for
high-speed can-making lines.
Features & Characteristics
Premium MR Steel Base: Manufactured from low-carbon MR grade steel, ensuring excellent
purity, weldability, and consistent mechanical properties for
superior formability.
Functional Matte Finish: Provides a smooth, low-glare surface that enhances coating
adhesion and reduces light reflection, ideal for high-quality
printed packaging.
Optimized Temper Grades: Specifically supplied in T4CA and T5CA tempers, offering the
perfect balance between ductility for deep drawing and the
necessary strength for container rigidity.
Superior Corrosion Defense: The combination of the tin coating and passivation treatment
offers robust resistance to oxidation, rust, and internal corrosion
from acidic or alkaline contents.
Manufacturing Flexibility: Suitable for both soldering and modern welding techniques, and can
be supplied with custom internal/external lacquers or pre-printed
to specification.
Key Advantages
Choosing our MR grade Electrolytic Tin Plate delivers tangible
production benefits. Its exceptional consistency minimizes breakage
and tool wear during stamping and drawing, increasing line
efficiency. The matte finish reduces coating costs and ensures
brilliant print results for standout shelf appeal. Furthermore, its
compliance with major international standards (JIS, DIN, ASTM)
guarantees global acceptability, while the option for custom
packaging (rust-proof paper, metal angles) ensures pristine
material arrival.

Frequently Asked Questions (FAQ)
Q1: What is the main advantage of MR steel over other grades for
tinplate?
A1: MR (Miller Rated) steel is specifically designed for high
corrosion resistance and exceptional drawability. It contains
controlled residual elements, making it the preferred,
cost-effective choice for most food packaging applications where
superior forming and welding are required.
Q2: Why choose a matte finish over a bright finish?
A2: A matte finish reduces surface glare, provides a sophisticated
appearance, and creates a microscopically rougher surface profile.
This significantly improves the adhesion and bonding strength of
subsequent protective lacquers and decorative inks, reducing the
risk of coating delamination.
Q3: What does the "CA" in T4CA/T5CA signify?
A3: "CA" stands for Continuous Annealing. This modern annealing
process results in a more uniform and consistent temper across the
entire coil compared to batch annealing, leading to better
formability and fewer production issues in high-speed can
manufacturing.
Q4: Can you apply internal lacquer or external printing in-house?
A4: Yes. We offer comprehensive pre-treatment services. The
tinplate can be supplied with custom internal protective lacquers
(epoxy, phenolic) for specific food products and with
high-definition external offset printing based on your provided
artwork (CMYK/PMS).
Q5: What is your packaging standard for export?
A5: We use seaworthy, heavy-duty packaging to prevent damage. This
typically includes VCI rust-proof paper, plastic film wrap,
reinforced metal corners, steel strapping, and secure mounting on
wooden pallets, ensuring the material arrives in perfect condition.
