  We consider two twist operators that lead to kappa-Poincare Hopf algebra, the
first being an Abelian one and the second corresponding to a light-like
kappa-deformation of Poincare algebra. The advantage of the second one is that
it is expressed solely in terms of Poincare generators. In contrast to this,
the Abelian twist goes out of the boundaries of Poincare algebra and runs into
envelope of the general linear algebra. Some of the physical applications of
these two different twist operators are considered. In particular, we use the
Abelian twist to construct the statistics flip operator compatible with the
action of deformed symmetry group. Furthermore, we use the light-like twist
operator to define a star product and subsequently to formulate a free scalar
field theory compatible with kappa-Poincare Hopf algebra and appropriate for
considering the interacting phi^4 scalar field model on kappa-deformed space.
