Product Description:

1.Structure of Electrolytic Tin Plate Coils and Sheets for Foods Metal Packaging Description

 

Electrolytic Tin Plate Coils and Sheets for Foods Metal Packaging,  is one thin steel sheet with a coating of tin applied by electrolytic deposition. Tinplate made by this process is essentially a sandwich in which the central core is strip steel. This core is cleaned in a pickling solution and then fed through tanks containing electrolyte, where tin is deposited on both sides. As the strip passes between high-frequency electric induction coils, it is heated so that the tin coating melts and flows to form a lustrous coat.

 

2.Main Features of the Electrolytic Tin Plate Coils and Sheets for Foods Metal Packaging

 

Appearance – Electrolytic Tin Plate 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 – Electrolytic Tin Plates have excellent paintability and printability. Printing is beautifully finished using various lacquers and inks.

Formability and strength – Electrolytic Tin Plates 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 – Electrolytic Tin Plates 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.

Q:How to test the tightness of tin metal cans?
The empty tank which has been cleaned can be dried by 35, and the pressure or pressure leak test shall be carried out according to the equipment condition of each unit. B.1 pressure leak test, the empty tank will be carefully injected into the water until eight or nine into full, the rubber ring will be placed in the appropriate plexiglass plate at the opening side of the roll, so that it can be sealed. Start the vacuum pump, turn off the bleeder valve, hold down the cover by hand, control the pumping, and make the vacuum gauge rise from 0Pa to 6.8X10 PA (510mmHg) for more than 1min, and keep the vacuum above 1min.
Q:What's the head iron?
SPTE, which is commonly known as tin, tin plate, thickness of 0.15-0.3mm, width, generally between 300-900mm.
Q:Is to buy canned tinplate or aluminum
Tinned food is usually made of tinplate, because the strength of tin is higher than that of aluminum cans, and the tin can not be deflatedAluminium is generally used in carbonated beveragesTin can be best served from the point of view of transport
Q:Is it necessary for the two cold rolling in the process of tinplate production, such as tempering and cold rolling (also called flatness)?
Generally used in rolling and sheeting. The tinplate is usually below 0.2mm and needs to be subjected to 2 cold rolling. Of course depends on the thickness of the raw material.
Q:What is the process of two cold rolling of tinplate?
Tinplate is commonly known as tin plated steel sheet. The English abbreviation is SPTE. It is a cold-rolled low carbon steel sheet or strip coated with commercially pure tin on both sides.
Q:Does the tinplate have a tensile rate? Thank you heroes!
Elongation or section shrinkage is the main index of plasticity of metal materials. The quality of plasticity depends on many factors, and the material is only one of them. For example, temperature and stress state will also affect the plasticity. Marble in high-pressure liquid can also be a good extension of humor.
Q:Advantages and disadvantages of tinplate packaging
Because of these properties, so can provide a besides the heat, completely isolated from the closed system of environmental factors, avoid color food because of light, oxygen, moisture and deterioration, nor because of aroma through and become weak or affected by environmental pollution through the smell and taste, stability is better than that of other packaging materials of food storage. Vitamin C save the highest rate, nutrient retention is the best. International environmental management standards will be implemented soon based on ISO-14000, has the advantages of low pollution, tin recycling, resource characteristics, in the future packaging applications, will have a broader space for development.
Q:Tin can weldingHow can the side of the column of the pop top be welded or pressed?,
The iron material thickness uniformity in the welding process, welding voltage and high requirement of control, the slightest mistake will cause breakdown or welding point is easy to fall off. As for the production of specific steps, personal suggestions to the scene you see, because the whole process is relatively simple, and when it comes to the production process and principle very boring, tedious. So, if you just want a rough understanding, there is no need for this.
Q:What about tin cans?
Galvanized iron: galvanized iron for daily use, such as box, water pipe, etc.Tin: tin plated iron. Usually used for food packaging. Such as canned goods
Q:Why tin printing after a layer of light oil
Bright oil is common in epoxy resin, alkyd resin, acrylic resin, acrylic amino, etc., the composition is different, the performance is also different, and the use is not the same. Usually according to the process whether there is a deep stamping deformation, welding local high temperature heating and the need for high pressure cooking and so on, choose different types of varnish.In order to increase production efficiency and save energy, in general, the last printing process is combined with the glazing process.In addition to the roller coating can be used, but also can be printed light ink method, both gloss is not much difference, but the processing performance is better than roller coating.
