Film & Paper Thickness Tester

Film Shrinkage Test Equipment Film Shrinkage Tester GBK-D1
Film Shrinkage test, known as linear thermal shrink test or free shrink test, is used for analyzing the effect of temperature on heat shrinkable films made from polyethylene, ethylene copolymers and their mixtures. Basically, shrinking force, contracting force and shrinking ratio can be measured in such determination.

GBPI Film Shrinkage tester conforms to the multiple national and international standards:
ASTM D2732 - Standard Test Method for Unrestrained Linear Thermal Shrinkage of Plastic Film and Sheeting
ISO 14616 - Plastics Heatshrinkable films of polyethylene, ethylene copolymers and their mixtures Determination of
shrinkage stress and contraction stress
DIN 53369 - Testing of plastic films determination of the shrinking stress

Film Shrinkage Test Equipment GBK-D1 is used to determination of the degree of unrestrained linear thermal shrinkage and dimensional stability at different temperatures. Widely used in industries of plastic material, plastic products, petroleum, chemicals, research institute, inspection agency and so on.

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 to cool down.
The reference temperature, shrinkage force and displacement are recorded, and the recorded data can be used to determine the optimal shrinkage conditions of the film.

Standards
ISO 14616, ASTM D2732, DIN 53369

PET release liner with silicone coating, PET protective film with silicone or acrylic adhesive, release paper. widely used in medical, food, consumer industry with stable release force.
