Technology currently exists to produceblown film with up to 77 layers.
The most common number of coextruded layers in use today is 3 layers,with a trend to5-and 9-layer films.
As mechinery advances are made,new product structures are created to fufill various market needs.
A balance will be struck between the cost of new capital equipment required to make 7/9/11-layer films,and
the benefit derived from doing so.
The competition is not necessarily another machine supplier,or from a lower cost producer,
but from another technology that can laminate unlike films to produce similar structures,
namely adhesive lamination and extrusion laminations.
These technologies have coexisted for many years,and likely to do so for the future.
