Stretch Wrap Films for Transport Packaging requires many indexes for physical and mechanical properties, including tensile force, adhesiveness, elastic recovery, permanent deformation, tensile maintenance, force value, puncture resistance, unit area quality deviation, transparency, fogging degree and water vapor permeation quantity, etc.
  Meanwhile,in order to determine whether wrap film is capable of protecting the goods free from wetting and moisture absorption during voyage or humid environment, the testing for water vapor transmission quantity is of vital importance.
