热分析在多层包装薄膜中的应用
|
| Multilayer thin films are becoming more common as manufacturers and users of plastics for film applications such as packaging strive to develop materials with a balance of endues properties (e.g., toughness, selective atmosphere permeability). An important quality parameter for these multilayer films is the total film thickness, as well as thickness of the individual component layers. Thermomechanical analysis (TMA), because of its ability to measure small dimensional changes, is ideal for evaluating thin films. TMA provides an alternative to spectral techniques, particularly in situations where the presence of inks, adhesives or lacquers might interfere with the measurement. |
