Multi-layer Packaging Films: More Flexural Strength for Thin Films
With the help of a computer simulation it is possible to visualize the effects of the targeted positioning of functional materials and different sealing media on film flexural strength. Results for specimen systems show that ionomers, which have stiffnesses that can be adjusted within broad limits as well as very good sealing properties, offer a wide range of opportunities to reduce the thickness of such multi-layer films without at the same time having to accept a loss in flexural strength.
