Description

TESTRON TT-BK2 Film Heat Shrinkage Tester evaluates the key thermal shrinkage properties of film products. Traditional oven or oil-bath methods mainly determine the heat shrinkage rate of heat-shrinkable films, providing relatively limited test data.

The TT-BK2 provides a more comprehensive evaluation of film thermal shrinkage performance with accurate test results and easy operation. It is designed to provide reliable and comprehensive test data to meet various film testing requirements.

Applications of TT-BK2 Heat Shrink Tester

Suitable for heat shrinkable films which produced with polyethylene, ethylene copolymers and their mixtures, such as beverage labels, bottled bundle packaging, sausage shrinkage packaging, outer film of daily chemical products, outer film of cigarette boxes, etc

Test Standards of TT-BK2 Heat Shrink Tester

GB/T 34848-2017、ISO 14616-1997、DIN 53369-1976

Test principle of TT-BK2 Heat Shrink Tester

This tester uses the principle of air heating to connect the tested sample to the tension sensor and displacement sensor. After reaching the maximum shrinkage force, it is placed in an external test environment with an ambient temperature of 23°C ± 2°C to cool down, the instrument continuously records the reference temperature, shrinkage force, and displacement, the recorded data can be used to determine optimal shrinkage conditions for the film.

Features of TT-BK2 Heat Shrink Tester

Laser measurement technology, non-contact precise measurement.
High-precision force sensor and displacement sensor can accurately determine the thermal shrinkage performance parameters of the sample.
Automatic temperature control, intelligent digital PID algorithm.
The system displays the heat shrinkage force, cold shrinkage force and heat shrinkage rate in real time during the test.
