Tensile strength and elongation for plastic flexible packaging

Packagings tensile strength and elongation are essential when it comes to the packaging strength. The heat sealing strength, pressure resistant property, drop performance and puncture resistance of packaging are all closely related to it.


In production practice, we often pay attention to the detection of heat sealing strength and peeling strength of packaging bag instead of materials tensile strength and elongation. In fact, they are the most important factors which must not be ignored for products R&D and design.


Packagings tensile strength and elongation mostly depend on the packaging materials properties and their combined properties.
