Problems solved by technology

However, when the airtight sheet of wrapping material is folded into a U-shape, the filter of a cigarette is subjected to enormous mechanical stress
It is important to remember that the filter is visible when the pack of cigarettes is opened, therefore any deformed filter is very negative due to the impression that the cigarette is defective
Moreover, the packaging method described above does not allow a right-angled edge to be formed at the filter due to the hardness of the sheet of inner wrapping material that deforms the filter and thus the rounded edges.
