HOLASA
classified in this way the film produced according to quality:
"FIRST QUALITY ":
Quality first is the normal production of electrolytic tinning line subject to the usual procedures of inspection and testing of finished product, this film is suitable for lithographic coatings and in general can be used to its fullest extent. It should also be free of holes, wrinkles, breaks, bumps and lumps of tin inlaid on the surface.Request
 |
"STANDARD QUALITY ": Material in sheet form which is the product for inspection at the production line, with a mix of first quality criteria and up to 5% of quality second. It is suitable under normal storage conditions, lithographic coatings and general purpose tin. This film should be free of holes, wrinkles and lumps of tin inlaid on the surface.

"SECOND QUALITY": The production quality is second rejected and / or classified electrolytic tinning line subject to the usual processes of inspection and testing of finished products and / or grading banks. You can file bankruptcy, wrinkles, dents, rust in the form of maps. Ties are not allowed to film.

Electrolytic Tinplate
Electrolytic TinPlate: Composition
E.T.P. consists of five layers each of which performs a different role:
1. Steel Base: Provides stiffness to the material due to its thickness and mechanical strength. Its chemical composition imparts special properties to resist corrosion.
2. Iron-Tin Alloy: This is made up by the inter-metallic compound Fe-Sn2. Due to its electrochemical characteristics, it acts as a barrier against corrosion. For effective action, its continuity is more important than its quantity.
3. Metallic Tin: Tin has many advantages which have turned it into the most important element to protect steel used for cans; in many foods, it acts as a simple barrier against corrosion, improves weldability, it is an excellent base for lithographic printing and for applying lacquers. In tin-robbing foods, it acts as a sacrificial element.
4. Passivation Film: According to its nature, it makes it possible to improve the E.T.P.’s resistance to sulphiding, oxidation and rust. It is also a conditioner to improve the adherence of varnishes, inks, lacquers etc.
5. Oil Film: Protects the sheet from the humidity in the environment and makes easy to handle. It is applied using an electrostatic oiler on both sides of the sheet.
