Long-Cap
What is a LongCap (LC) actually and how are they made? The LongCap is an aluminum screw cap closure and is deep-drawn from offset-printed aluminum sheets that are 0.22 to 0.24 mm thick. The deep-drawing takes place in two steps, in case of LC 30 x 60 mm in three steps. In the process, the aluminum is stretched so much that a print design on the side would no longer be recognizable. That’s why a special side print method, similar to that for tubes, sleeves, etc., is used. Particular attention is given to the quality of this side print, since it also serves as an advertisement later when the product is on the shelf. The following sizes have had great success on the market:
