Labthink Heat Shrink Film Force at Break Testing Equipment

Product catalog summary

Introduction
Shrink-film is commonly used as an over-wrap for various packaging types. The shrinkage occurs when heat is applied, causing the film to tightly enclose the object due to the relaxation of orientation stresses introduced during production.

Labthink FST-01 Shrinkage Tester
The Labthink Shrinkage Tester is designed to measure two key parameters: shrink ratio and shrink force.

Shrink Ratio: The test sample is attached to a load cell with a displacement transducer and heated to a specific temperature. Displacement signals are recorded, and the shrinkage ratio is calculated.
Shrink Force: Based on DIN 53369, the sample is briefly placed in a hot oven and then cooled to room temperature. The force generated during material shrinkage is recorded.

Standards
The tester complies with ISO 14616-1997 and DIN 53369-1976 standards.

Features

Capability to test 3 groups of distinct or equivalent specimens simultaneously.
Real-time display of shrinking force, contracting force, shrinkage ratio, and temperature curve.
Operated using a standard monitor, mouse, and keyboard, eliminating the need for a PC.

Contact: Yarina Gao Email: [email protected] Phone:086-531-85060139 LABTHINK FST-01 SHRINKAGE TESTER Shrink-film is used as an over-wrap on many types of packaging. When heat is applied to the film it will shrink tightly over the object it is covering. The shrinkage of the films is based on the relaxation of the orientation stresses introduced in the film during the production of the film. The relaxation causes a good enclosure of the package. Labthink Shrinkage tester is designed to determine shrink ratio and shrink force:  Shrink ratio – Test sample is attached to a load cell, which is equipped with displacement transducer and is heated to a certain temperature. The displacement signals are recorded during the test and the shrinkage ratio is obtained by further calculations.  Shrink Force – Determined based on DIN 53369. Test sample is attached to a load cell and is placed briefly in a hot oven and subsequently cooled down to room temperature. The force that is build up during the shrinking of the material is recorded. Contact: Yarina Gao Email: [email protected] Phone:086-531-850
