GBK-D1 Film Heat Shrinkage Tester
Product Introduction
GBK-D1 tests various heat shrinkage properties for the film according to the principle of air heating (air bath). Suitable for heat shrinkable films 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.
It is a device that can accurately and quantitatively measure the thermal shrinkage force, cold shrinkage force, shrinkage rate, shrinkage time and other properties of plastic films during thermal shrinkage.
Test Principle
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.
Standards
ISO 14616-1997, DIN 53369-1976, GB/T 34848-2017
