THMH is a one side heat sealable, other side high barrier metallised CPP film. Treatment value on metallized side tends to decay over a period of time during transportation and storage condition. Therefore it is recommended to check the treatment level prior to processing and if necessary refresh the treatment prior to conversion to ensure optimal adhesion of inks and adhesives but avoid backside treatment. Film should be stored in a dry environment at a temperature under 30 Deg. Allow the film to reach room temperature at least 24 hours before use.
