Product Description
У "The FST-01 Film Free Shrink Tester is used to measure the unrestrained linear thermal shrinkage of plastic film and sheets at specified temperatures in a fluid medium. This device helps assess how much these materials will shrink when exposed to heat in real-world applications.
In the manufacturing process of plastic films and sheets, the material undergoes stretching, leading to internal stresses that can result in shrinkage when exposed to heat. Understanding and controlling this shrinkage is crucial for ensuring product quality and process consistency.
Our shrink film testing equipment is designed to accurately perform film shrink tests, evaluating the shrinkage properties of various films. The film shrink tester ensures precise measurements, allowing you to assess the performance and durability of shrink films under different conditions.
2.Advantages of FST-01 Film Free Shrink Tester
Accurate temperature control through P.I.D. technology
High-precision timing functionality
Alarm system for enhanced monitoring
Uniform heating of the fluid medium
Comes with a standard square metal clamp and a complimentary free shrink holder

3.Why do you need FST-01 Film Free Shrink Tester
У "The FST-01 Film Free Shrink Tester is an ideal tool for manufacturers and researchers involved in the production of plastic films and sheets with shrinkage features.
In general, shrink film is commonly used as the material for heat shrinkage packaging. The suitability of the shrinkage rate of materials is crucial, as it can impact the appearance of the products. An excessively high shrinkage rate may distort printing patterns or even result in the breakage of the seal interface. Conversely, a too low shrinkage rate could lead to issues such as labels falling off.
FST-01 Film Free Shrink Tester is suitable for conducting heat shrinkage tests on various types of films in a liquid environment under different temperature conditions.
4.Application
У "The FST-01 Film Free Shrink Tester finds is applicable for testing the heat shrinkage performance of various films in a liquid medium at different temperatures, such as PE shrink films used for overall packaging of alcoholic beverages, canned beverages, bottled water, and various types of drinks. Also suitable for shrink films like PVC, POF, OPS, PET, etc., designed for various packaging applications.
