ETP Food Can JIS G3303 Customizable Electrolytic Tinplate Coil For
Canning Industry
1. Introduction
Tinned steel plate (commonly known as tinplate) is a steel product
that can be stamped with a thin steel plate as the matrix, and is
coated with tin on its surface and has a multi-layer protective
film (layer). It has the characteristics of corrosion resistance,
non-toxic, tasteless, surface gloss, light weight, high strength
(relative to paper, wood, composite materials), easy to paint, easy
to weld and process molding, and strong adaptability to
environmental temperature. Therefore, more than 70% of the total
output of tinned steel plates is used for food and beverage
packaging. In addition, it is also the packaging and raw material
shake of chemical and pharmaceutical, mechanical and electrical,
hardware, telecommunications and other industries
2. Features of ETP Products
By selecting a proper coating weight, appropriate corrosion
resistance is obtained against container contents.
Printing is beautifully finished using various lacquers and inks.
TIN PLATE is widely used for making various types of cans by
soldering or welding.
By selecting a proper temper grade, appropriate formability is
obtained for various applications as well as the required strength
after forming.
Electrolytic ETP is characterized by its beautiful metallic luster.
Products with various kinds of surface roughness are produced by
selecting the surface finish of the substrate steel sheet.

The hardness is the average value of 2 samples, allowing 1 of them
to exceed the specified allowable range by 1 unit. |
a The yield strength is a reference value determined as required. b Yield strength is the average value of the two samples. The
sample is P5 in GB/T 228, and the direction of the sample is
transverse. c Due to the thickness thinning effect, the elongation is too low
and the yield strength cannot be measured. In this case, the yield
strength is replaced by the tensile strength. d For the tensile test, the width of the parallel part of the
sample is (12.5±1) mm, and the standard distance L0=50mm. Before
the test. The sample should be artificially aged for 20min at 200℃. |

4. Typical Applications
Typical Applications including:
Consumer Packaging and Industrial Packaging
TINPALTE
ETP is primarily used for packaging foodstuffs and beverages, but
it is also used in containers for oils, grease, paints, polishes, chemicals and many other
products. Aerosol containers and caps and closures are also made from ETP.
TFS
TFS are most frequently used for can tops, screw and lug caps, snap
and press-on closures and shallow-drawn food cans.
5. Miscellaneous
in Electronics
– Electrodes, Cable tape, Magnetic screen covers, etc.
in Engineering
– Automotive oil filters, Automotive air filters, Gaskets, etc.
in Construction
– Gas meter internal components, Heat exchangers, etc.

8. APPLICATIONS
Our food tinplate can offers a good source of iron for its users.
Tinplate canned food, except few light color fruit and canned
fruit, mainly adopts interior painted empty cans for improved
corrosion resistance of containers. Under the electrochemical
action of metal, a small quantity of iron dissolves out of enamel
cans and exists as ferrous iron in the sealed canned food, ranging
from 1ppm to 10 ppm, which is easy for people to absorb. Provided
that there is 5ppm iron in every 350ml tinplate can, then each can
of food can provides 1.75mg iron, which is about one tenth of 18mg
daily iron intake by human body. In case of rich vitamin C
contained in the canned fruit and vegetable juice, iron will be
easier for assimilating. That is why this food tinplate can is so
widely adopted for packaging food.
9. EXPORT PACKAGE
