plastics: qualitative determination on PVC / PVDC / chlorinated

PVC is a very resistant and durable material. This is good for long-life products such as window frames, but it is completely unnecessary for disposable articles like plastic packaging for milk products. The longevity becomes a problem when it is time to dispose of the product. Therefore, from an environmental point of view, It should not be used in short-lived products. This test is for the qualitative determination of PVC in plastics.
