With fully resistant lacquer coating, the minimum amount of tin coating on interior surfaces is 6.5 g / m2. Tin coating on external surfaces should be at least 8.2 g / m2 if a suitable and durable secondary coating is used, and at least 6.5 g / m2 if secondary coating is not used.

Comprehensive Guide for buying Top notch steel cans
Classification of steel sheets according to the amount of elements in them – L-type plate contains less phosphorus than other layers and this layer is generally used in the manufacture of cans for acidic and semi-acidic foods (medium acidity) such as colored fruits (cherry), grapefruit and pickles. There is a type of L-layer called LT, which is more corrosive than the L-type layer and is used for almost acidic foods.
- MS type sheet is similar to L type and contains more copper and currently these sheets are used to make canisters for Sawkrat packaging. This type of MR type plates are used in the production of special food boxes such as apricot, anise and peach, low acid foods such as pears, pineapple and dry foods such as green peas, meat and nuts and oil.
- MC type page uses MC like MR, but this page is less used today. The structure of this layer is high and its phosphorus is higher than other layers. – Type N plate This type of plate has 0.02-0.007% nitrogen to increase the strength of the body and is used in the manufacture of carbonated beverage cans.
- Type D sheet This type of sheet is suitable for making stretch cans and lids for aerosol cans and contains AL2O3 aluminum oxide.As a result of the tin reaction of the outer surface of the acid, the following two factors are performed in steel plates to increase the resistance of tin-plated steel to corrosion.
Civation: This action stabilizes the surface coating of the tin and is done by controlling the growth of the naturally occurring tin oxide film. Uncontrolled oxide growth causes yellow color on the surface of steel plates and consequently has a negative effect on the color and adhesion of the varnish.
Lubrication: Surface lubrication is the last process performed in steel plate factories.The main reason for this process is that when used in canned food, the sheets slide easily and the surface scratches and adhesion are reduced. Can manufacturers have considered composite classification for tin-plated plates.
This classification consists of seven combinations, from the softest layer that can be produced in the factory (T-1) to the hardest layer that can be used by canned food manufacturers. T-1 and T-2 sheets are used for stretch containers such as fish boxes and lids. T-3 and T-4 sheets are specially machined into the body of the food boxes. T-5 plates are for situations where greater resistance to bending or high compressive strength is required. For more information on steel cans sale visit our site.
