2.- diaper with narrow and straight central chassis with elasticated side panels in the front and in the back. This is a concept introduced by P&G and KCC and it is greatly widespread in US and EU.
3.- Diaper with refastenable closure system on the side panels. Mainly present in US.
Janus eliminates the need of side seam to connect the front and back portion of the pant-diaper and therefore simplify significantly the whole production process. The innovation consists of new product design with lateral elasticated panels with a mechanical closure system to connect each other. Even though this product configuration is not totally new the method to manufacture such product gives some advantage eliminating a lot of bottle necks in these type of processes.
