Shrink Wrapping - A technique
of packaging in which the strains in a plastic film
are released by raising the temperature of the film
thus causing it to shrink over the package. These
shrink characteristics are built into the film during
its manufacture by stretching it under controlled
temperatures to produce orientation of the molecules.
Upon cooling, the film retains its stretched condition,
but reverts toward its original dimensions when it
is heated. Shrink film gives good protection to the
products packaged and has excellent clarity.
