Film Heat Shrinkage Tester tests various heat shrinkage propertiesforthe filmaccording to the principle of air heating (air bath).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. 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 Firstly submerge the specimen in the water in the vacuum chamber, and then evacuate the vacuum chamber to form differential pressure between the inside and outside of specimen. The seal property can be obtained by observing the steady progression of bubbles from the specimen or observing how the specimen expands and restores to its original shape after vacuum release.

Heat Seal Tester is to test the temperature, pressure, and time for heat sealing of various film materials.

packaging barrier film water vapor transmission rate test also called moisture transmission rate test and WVTR

One test chamber water vapor permeability analyzer using weight reduction method is to test the water vapor transmission rate (WVTR) of films or sheets materials.

The Adhesive Tape Roller GX-Y2 is suitable for plastic film and cellophane decorative prints (including composite film prints) produced by gravure printing process. It is also used to test the adhesion state of the surface layer formed by vacuum coating, surface coating, compounding and other related processes.

The Coefficient of Friction Tester equipment performs tests to most of the recognised international test standards including IS0 8295 and ASTM 1894-78.

The Inclined Impact tester is simulated the impact strength of packaging in the real circumstance of transport such as handling, stacking of shelves, sliding, loading , transportation of products.
