The Hanatek FST, available from Novasys Group is a range of film shrink testers designed to measure the effect of temperature on plastic films in flexible packaging applications.

Film shrinkage is caused when certain plastic films rapidly contract on application of heat during sealing and packing of items from food to consumer goods. The shrink effect happens when internal forces locked into the film during manufacture are released by heating.

Also known as linear thermal shrink or free shrink, the shrinkage depends on the film type, thickness and sealing temperature.

Hanatek film shrink testers allow the percentage shrink of a film to be determined to ensure that it is suitable for a particular packaging application and establishes the correct temperature for that application.
