FSR-01 shrink force and ratio tester is used for the shrinking forces and shrinkage ratio measurement of heat shrinkable films.Heat shrinkable film is normally extruded and stretched (hot drawn) during manufacture and it remains in this state after cooling down. When the film is again brought up to the temperature at which the stress was induced and then fixed during its manufacture,this stress is liberated and the film shrinks back. Depending on the treatment applied, the film is called biaxially oriented or uniaxially oriented.
A well-insulated air oven is heated to the set temperature. The two samples are placed separately on two test stations, for
shrinkage rate and shrink/contraction force testing. A temperature probe is located to measuring area, to give result as reference temp. The air oven is driven down automatically to cover the sample area. The force and shrink rate are to be measured and the shrinkage temperature is reached when the maximum shrinking force is attained. When this force has decreased by around 15%~30%, the air oven is lifted and time is recorded. The assessment of shrinkage ratio is performed at the mean time.
