The basic material used in the production of crown corks is tin plate or chromium-plated steel (TFS)
which is cut into sheets for further processing. These materials are resistant to corrosion, suitable for
printing and deep-drawing and recyclable. Like all of our raw materials the tin plate and chromium-plated
steel is subject of detailed incoming goods inspections and tests.

The accuracy in
size of the cut sheet
is a key to final quality

Raw materials
The quality of the finished product is based upon the quality of the raw materials used. The main constituent used in the manufacturing of crown corks is either tin or chromium coated steel which has to comply with the highest quality standards. We have therefore made it our principle to only accept materials from established, certified suppliers. Systematic incoming goods in- spections and tests plus regular	audits contribute to reliable, safe processing. The other raw materials needed in the production of crown corks are lacquer, printing ink and plastic sealing. Our philosophy is to use only non-PVC lining materials. The choice of raw materials depends on technical demands and the decoration. The individual specification is determined between the customer and our sales department.
