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°C±2°C 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 14616-1997, DIN 53369-1976,
