Which of the following is a common application for PVC?

PVC, or polyvinyl chloride, is a versatile plastic commonly used in various applications due to its durability and resistance to environmental degradation. Among the options provided, yoghurt pots represent a fitting application for PVC because this material can be molded into containers that provide effective barriers for moisture and oxygen, which helps preserve the freshness of food products.

Yoghurt pots require materials that are not only strong and lightweight but also have good sealing properties. PVC meets these criteria by providing a moisture-resistant and durable container that helps to extend the shelf life of dairy products. Additionally, the clear or colored variations of PVC can be used to create visually appealing packaging that allows consumers to view the product inside.

In contrast, while adhesives, car bumpers, and biodegradable bags may use other types of materials or composites for specific properties, they do not typically feature PVC as a common or primary material. Adhesives often employ synthetic resins or rubber compounds, car bumpers are usually made from impact-resistant plastics like ABS or polypropylene, and biodegradable bags are specifically designed to break down in the environment and are often made from materials such as cornstarch or other bioplastics, rather than PVC, which is not biodegradable.
