Cutting to the Chase, Testing End-use Performance of Flexible Films
From shipping to storage to end-use, flexible films across multiple industries such as in medical, packaging, building and consumer products will see their share of abuse throughout the product lifestyle as they are bounced, pounced, slashed and mishandled. Therefore, one characteristic key for consideration with flexible film material selection is impact.
There are a number of standardized laboratory test methods to simulate impact in application. Three common tests performed on polymer films and flexible materials to simulate impact include:
To determine the test best for each application, it is important to understand the types of impact stress a film will experience. Three characteristics to consider when choosing a test procedure are location of impact, type of impact and speed of impact. Consider real examples:
When evaluating impact, choose the best test, or multiple tests, to match application forces for the product. Keep in mind: each of these standard procedures can be optimized through modifications of impact tup, speed and configuration. In the end, a clear understanding of potential hazards in the field and knowledge of available test procedures is the best way to design a test program to understand impact.
