Evaluation of Plastic Materials Evaluation of Mechanical Characteristics of Various Plastic Products Using
Autograph
The four figures below are examples of results from using a Shimadzu AG-X Autograph precision universal testing machine to evaluate static
mechanical characteristics of some typical plastic products. This data allows determining the fundamental characteristic values that are the
most important for mechanical design, such as strength, elongation, elasticity, and energy absorption.
These tests were performed in accordance with JIS standards applicable to the given specimen (sample) shape and test methods.

Evaluation of Plastic Film Characteristics Using Autograph
Thin plastic film materials are increasingly being used for functionally engineered materials. Therefore, it is critically important to understand
their characteristics, not only for controlling their functionality and performance, but also for use in developing new applications.
As one example, a 38 µm thick polyester film was evaluated to determine any differences in mechanical characteristics in directions parallel
and perpendicular to the direction it was stretched (due to mechanical stretching processes during film manufacturing).
