Polyolefin Films with Linear Motor Driven Simultaneous Stretching Technology

The simultaneous stretching technology with
linear motors provides new possibilities for the
production of biaxially stretched polyolefin films,
e.g. BOPP and BOPE shrink films. The
development of new film types is done in the first
stage on a discontinuous frame stretcher in a
laboratory scale and from there, transferred in a
continuous process onto a pilot line. This
development environment represents the basis for
the transfer to production scale and has meanwhile
been realized on several large scale production
lines. The given examples shall outline the
outstanding properties of shrink films achieved
with this technology.
