PP/EVOH films, which are multilayer films combining polypropylene (PP) and ethylene-vinyl alcohol copolymer (EVOH), offer several advantages due to the unique properties of each component:

1. **Excellent Barrier Properties**: EVOH is known for its outstanding barrier properties against gases such as oxygen, carbon dioxide, and aromas. This makes PP/EVOH films ideal for packaging products that require protection from these elements.

2. **Heat Resistance**: Polypropylene provides good heat resistance, making PP/EVOH films suitable for applications involving high-temperature processing or storage conditions.

3. **Chemical Resistance**: PP/EVOH films have good chemical resistance, making them resistant to many types of chemicals, which can be beneficial in various industrial applications.

4. **Flexibility and Durability**: The combination of PP and EVOH results in a film that is flexible yet durable, offering good mechanical strength and flexibility. This makes it suitable for a variety of packaging needs.

5. **Transparency**: PP/EVOH films can be made with good transparency, allowing consumers to see the product inside the packaging, which can be an advantage for marketing purposes.

6. **Sealability**: PP is easily sealable, which means PP/EVOH films can be sealed effectively to ensure the contents remain protected.

7. **Cost-Effectiveness**: Depending on the application, PP/EVOH films can be cost-effective compared to other materials that provide similar properties but may be more expensive.

These properties make PP/EVOH films particularly useful in food packaging, pharmaceuticals, and other industries where barrier protection, durability, and heat resistance are crucial.
