1.Structure of Quality Electrolytic Tinplate Coils For Metal Package Useage Description


Electrolytic Tinplate undoubtedly enjoys the pride of place as a packaging medium especially for food. It owes its unique position to its "nine layer sandwich structure", each of which contributes to its eminence as a packing material. The steel base of electrolytic tinplate provides the necessary strength and formability for can fabrication. The tin-iron alloy layer provides the bond between the steel and free tin layer. The free tin layer is not only responsible for the attractive bright finish and ease of solderability but is also non-toxic- a factor of vital importance in food packaging!


2.Main Features of the Quality Electrolytic Tinplate Coils For Metal Package Useage


Appearance – Tinplate 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.

Paintability and printability – Tinplates have excellent paintability and printability. Printing is beautifully finished using various lacquers and inks.

Formability and strength – Tinplates have got very good formability and strength. By selecting a proper temper grade, appropriate formability is obtained for different applications as well as the required strength after forming.

Corrosion resistance – Tinplate has got good corrosion resistance. By selecting a proper coating weight, appropriate corrosion resistance is obtained against container contents. Coated items should meet 24 hour 5 % salt spray requirement.

Solderability and weldability – Tinplates can be joined both by soldering or welding. These properties of tinplate are used for making various types of cans.

Hygienic – Tin coating provides good and non toxic barrier properties to protect food products from impurities, bacteria, moisture, light and odours.

Safe – Tinplate being low weight and high strength makes food cans easy to ship and transport.

Eco friendly – Tinplate offers 100 % recyclability.

Tin is not good for low temperature applications since it changes structure and loses adhesion when exposed to temperatures below – 40 deg C.

5.FAQ of Quality Electrolytic Tinplate Coils For Metal Package Useage


- What is tinning and how does it work?

  Tinning is the process of thinly coating sheets of wrought iron or steel with tin, and the resulting product is known as tinplate. It is most often   used to prevent rust.


- Do you only have prime quality tinplate?

  We can supply both prime and second quality tinplate.

Q:Cookies with tinplate packaging has what advantage?
Mature technology and high production efficiency: the production of tinplate has a long history, mature technology is a set of production equipment with matching, high production efficiency, can meet a variety of product packaging needs.
Q:How to test the tightness of tin metal cans?
Pressure leakage test with a rubber plug when empty hole plugged, start the air compressor, slowly open the valve, the pressure in the tank is increased gradually, while the empty tank is immersed in the water tank, careful observation with outer bottom cover curling and welding seam has no air bubbles, until the pressure rose to 0.7jg/cm and 2min. All the same parts of continuous bubbles, should be judged as leakage, leakage of the recording time and pressure, and mark in the leak site on.
Q:What is the use of tinplate printing tin, storage of food safety
Electrophoresis on a layer of special coating with food packaging, the packaging is extremely tight, in order to packaging material appearance, appearance are printed with various patterns, because it is the coating of food grade materials, so the food packaging is safe in the warranty period.
Q:How to open cans
Put the tins of canned fruits soaked in hot water for 3-5 minutes, so that the tank gas temperature rises, the pressure is increased, which is the principle of expansion and contraction. Turn the canned fruit bottle upside down for a while. When the liquid in it breaks down the vacuum inside and outside, tap it in the bottom with your palm and pull it gently. It's easy to pull apart.
Q:Is to buy canned tinplate or aluminum
Tinplate, our company sells tinplate
Q:How do you paint the tinplate?
Looking for tin printing cans factory processing back. Printing waste rate of 1000, there are 5 waste or so.
Q:Tin, tin plated iron. Why can't we get white wine?
Should be caused by the unqualified corrosion resistance of the tinplate. The reasons are as follows:Tin plating on the surface of the tinplate has played a certain role in corrosion protection, tin surface will be six chromium passivation, further improve the corrosion resistance. However, the liquor contains a lot of water, and if the long-term contact with the iron (without coating tin), the surface of the tin layer will be corrosion, and then corrosion to iron.
Q:How to distinguish galvanized plate and tin plate
The zinc plating on the galvanized sheet has no grain on the surface of the galvanized sheet under the optical microscope. Drip water on galvanized sheet can form more spreading water droplets, while on tin plate, water drops will shrink rapidly.
Q:Can tinplate be shielded?
But the tin incision as mentioned above is easy to rust, now the mobile phone but also through the salt spray test, so the comparison with foreign paktong insurance. I was listening to the supplier of phosphor bronze, copper - and Ocean high strength, good solderability, a little expensive Yu Yang white copper, but the large amount of words is not obvious! The shield is also made of stainless steel, but because of poor weldability, it is only used on two pieces of COVER (COVER, FRAME)! I don't know. Is that right?
Q:Can you tell me how to deal with the recycling of tinplate?
General tinplate packaging waste, as long as the rust is not serious, can be converted into hardware products, to achieve the best use of materials. The consumption of tinplate in our country is relatively large (600 thousand tons / year), and 125 tons of tin packing waste can be recovered 1 tons of tin.
