Abstract
Production of paper-based packaging is growing at the
present moment and has great future prospects. However,
the development of new packaging concepts is creating a
demand for an improvement in the mechanical properties of
paper. Extensibility is one of these properties. Highly
extensible papers have the potential to replace certain
kinds of plastics used in packaging. Extensibility is
also important for the sack and bag paper grades and for
runnability in any converting process. This paper reviews
the factors that affect the extensibility of fibres and
paper, and discusses opportunities for improving the
straining potential of paper and paper-like fibre
networks. It is possible to classify factors that affect
extensibility into three main categories: fibre
structure, interfibre bonding, and structure of the fibre
network. Extensibility is also affected by the straining
situation and the phase state of the polymers in the cell
wall. By understanding the basic phenomena related to the
elongation, and by combining different methods affecting
the deformability of fibre network, extensibility of
paper can be raised to a higher level.
