Product quality


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.


"SURPLUS": Are cuts, scraps, rejected by-product of electrolytic tinning line for compacting scrap, which is fully oxidized uncoated sheet, Tin with wrinkles over 40% of surface area and oxide Tin over 60% of surface area.






Metric conversion table


Electrolytic Tinplate (ETP) is a heterogeneous material structure and the Tin Free Steel (TFS) consists of four layers, each of which has a different function. The protective film of chromium varies between a range of 0.05 mm to 0.1 mm in thickness, equivalent to a range of 50 to 100 milligrams per square meter.

Tin Free Steel (TFS) is used mainly in applications where tin is not required as an element of sacrifice and it should be fully lacquered.

The food will remain in perfect condition as long as the strike has not damaged the surface of the can to the point where it drips, breaking their seal.
