POF and PVC are two common heat-shrinkable film materials, both of which offer good shrinkage and transparency and can be used to package a wide range of products. However, there are some differences between the two materials in terms of performance, cost and environmental friendliness, so the choice depends on the specific application requirements.
1. Performance Comparison
| Performance indicators | POF | PVC |
| Shrinkage | High | Medium |
| Transparency | High | High |
| Strength | High | Low |
| Toughness | Good | Poor |
| Cold resistance | Good | Poor |
| High temperature resistance | Medium | Good |
| Corrosion resistance | Good | Good |
| Odor | No | Yes |
| Recyclability | Recyclable | Difficult to recycle |
2. Cost Comparison
The cost of POF is usually higher than that of PVC due to the higher raw material price of POF. However, the thickness of POF can be thinner than PVC, so the unit cost of POF may be lower in actual use.
3. Environmental protection
POF is a recyclable material, while PVC is difficult to recycle. In addition, PVC releases toxic gases during the production process, so it is more polluting to the environment.
4. The scope of application
Both POF and PVC heat shrinkable films are used in the packaging of various products, but there are some differences between them in specific application areas.
- POF heat-shrinkable film is commonly used in the packaging of food, beverage, pharmaceuticals, cosmetics, electronic products and other products.
- PVC heat shrinkable film is commonly used in the packaging of toys, stationery, daily necessities, hardware tools and other products.
5. Other factors
In addition to performance, cost, environmental protection and application scope and other factors, in the selection of POF and PVC heat shrinkable film also need to consider the following factors:
Packaging speed
The melting point of POF is lower than that of PVC, so the packaging speed of POF is faster.
Packaging appearance
The surface gloss of POF is higher than that of PVC, so the packaging appearance of POF is more beautiful.
Conclusion
POF VS PVC heat shrink film has their advantages and disadvantages, the choice of which material depends on the specific application requirements.
- If you need high shrinkage, high strength, high toughness, cold resistance and good recyclability, POF is a better choice.
- If high transparency, heat resistance and low cost are required, PVC is the better choice.
