Understanding and Testing the Tensile Properties of PVC Film
2024-12-30
The quality of PVC film available in the market varies significantly, with some products demonstrating excellent durability and others falling short in performance. Here, we outline a practical method for evaluating the tensile properties of PVC film, ensuring compatibility with machinery and extending the service life of critical machine components.
One straightforward way to test PVC film is by pulling it by hand. By observing how the film responds to manual tension, you can gauge its strength and flexibility. A high-quality PVC film should have a strong tensile property, resisting breakage and maintaining stability when stretched. Films that exhibit these characteristics are typically more suitable for use in automated machinery.
In applications where the PVC film needs to be frequently cut, selecting a film with suitable tensile properties becomes even more critical. If the film is easily cut without fraying or tearing, it will place less strain on the cutter, helping to prolong the cutter's lifespan and maintain the machine’s overall performance.
Automated machines often have pre-set tension limits for handling film. If a PVC film lacks sufficient tensile strength, it can be prone to breakage under these conditions, causing machine downtime and reducing operational efficiency. Testing the tensile property before usage helps in identifying films that are more resistant to tearing, reducing the risk of unexpected machine interruptions.
Our company cooperates with a domestic film factory to jointly develop a film suitable for use on our food wrapping machine. The stretchability of the film can be referred to as follows. The width of the film generally used in our machines is 350mm, 400mm, and 450mm.
By conducting these simple evaluations, can ensure that the selected PVC film meets the required quality standards, enhancing machine efficiency and reducing maintenance costs over time.
