Product Description ETP & TFS Electrolytic Tinplate Tin coated steel coil sheet plate Product introductionSteels for packaging are thin gauge flat carbon steels, tin or chromium coated on both sides. This particular combination gives the tinplate an interesting set of properties: strength and stiffness, formability, welding ability, lacquer ability and printability, good cosmetic appearance and corrosion resistance. These properties bring appropriate response to all the necessary requirements: content protection during stocking and transportation, safe food preservation, printed information for the final user, ease of use, sustainability and environmental friendliness. Mass production of tinplate for canning human food started in year 1810, when Nicolas Appert wrote a famous book describing the technique of sterilization (also called "appertization") to preserve the food and when Peter Durand patented the same year the use of metal cans for the foodstuffs. Since then, tinplate has constantly taken advantage of dramatic improvements, especially over the past decades: improvements of the steel production processes (lower melting residuals and better inclusion cleanliness, switch from ingots to continuous casting, better temperature controls during hot rolling, high precision cold rolling), improvements of the coating process (hot dip tinning replaced by electro tinning to reduce the thickness of the tin layer), improvements of lacquers to increase the corrosion resistance, switch from soldering to electric welding for the can bodies. Unlike any other packaging material, steel is 100% infinitely recyclable and recycled. Thanks to its magnetic properties, steel packaging is the easiest and most economical type of packaging to sort and recover for recycling. Regardless of how many times it is recycled, steel loses none of its strength or inherent properties. Product specificationsCoatingAs mentioned earlier, there are two types of Steel for Packaging, depending on the metallic coating:? Tinplate with a tin coating and, in most of the cases, a passivation layer made of Chromium compounds? Electro Chromium Coated Steel (ECCS) or Tin-Free Steel (TFS) with a coating made of Chromium compoundsThe choice between these two products is sometimes imposed by the type of packaging or guided by the aimed aspect or by the product to be packed.Tin coatingTin coating is usually a three-stage process:1. electro tinning2. tin flow-melting (optional)3. chromium passivation (optional)PassivationThe tinplate surface is in most cases passivated to stabilize the surface, typically by preventing the growth of tin oxides. The most common is passivation 311. It is an electrochemical treatment in a bath of sodium dichromate to deposit both metallic chromium and chromium oxide on the tin surface. We are also proposing passivation 310, a lighter version of passivation 311, when a better lacquer adhesion is required.Chromium coatingChromium coating was primarily developed as an economic alternative to tin coating. It is an electrolytic treatment in a bath of chromic acid to deposit metallic chromium and chromium oxide on the blackplate. The usual name is Electro Chromium Coated Steel (ECCS) or Tin-Free Steel (TFS). TFS is excellent for lacquer adhesion and must always be lacquered both faces before use. TFS is not suitable for welding or soldering. Its appearance is less attractive (lower brightness) than tinplate. The absence of tin makes TFS non appropriate for acidic food (pH < 4) because of lower corrosion resistanceOilingOiling is necessary to reduce friction and scratches while handling the sheets. The three most common oil types are:? DOS = dioctyl sebacate? BSO = butyl stearate?
