Shrink Wrap Materials: PVC vs Polyolefin - Which is Better?
Shrink wrapping is a popular method to package products, and the two commonly used materials for shrink wrapping are PVC (polyvinyl chloride) and polyolefin. However, choosing between these options can be tricky. The following comparison will help you understand the differences between PVC and polyolefin and which one works best for your application.
Material Composition.
Polyvinyl chloride (PVC) is a plastic compound that contains some harmful chemicals like phthalates. PVC shrink wrap materials have been widely used but have faced criticism for their release of harmful chemicals when heated. Polyolefin, also known as polyethylene, on the other hand, is a petroleum-based material that does not contain any hazardous chemicals, making it an environmentally-friendly option. It also produces less odor when heated, unlike PVC that emits a distinct odor.
Protection and Strength.
When it comes to protection and strength, PVC has an advantage over polyolefin. PVC shrink wrap material is less permeable to moisture and oxygen, making it ideal for wrapping food and other perishable products where maintaining freshness is crucial. Additionally, PVC offers better resistance to punctures, tears, and abrasions compared to polyolefin.
Clarity and Appearance.
Polyolefin shrink wrap is known for its clarity and glossy appearance. Its clarity ensures that the packaged product is visible while protecting it from dust and contamination. Polyolefin shrink wrap is ideal for items like books, CDs, or DVDs where presentation is essential. PVC, on the other hand, has great printability, and it is possible to print a company’s logo or product information directly onto the wrap.
Environmentally-Friendly.
Polyolefin shrink wrap materials are considered more environmentally-friendly than PVC due to their chemical composition. The lack of hazardous chemicals in polyolefin materials ensures that they can be recycled and are biodegradable. However, PVC is not biodegradable and takes a long time to degrade. If you are looking for an environmentally-friendly option, polyolefin shrink wrap is a better choice than PVC.
Cost.
Ultimately, the cost of the shrink wrap material is a crucial factor to consider. PVC is relatively cheaper than Polyolefin and is a more affordable option for many businesses. However, keep in mind that the availability of the material differs by location and supplier. Polyolefin, although slightly expensive, offers excellent value for money and is a long-term cost-effective solution.
Conclusion.
Choosing between PVC and polyolefin shrink wrap materials will depend on the product and application. For applications where clarity and appearance are essential, polyolefin is an excellent choice. However, if your product requires better seal strength and more robust protection, PVC is a better option. When choosing between the two, it's crucial to consider the environment and the impact of the material on the planet. Fortunately, both PVC and polyolefin are readily available in the market, and finding a supplier shouldn't be a problem.
In conclusion, it's essential to consider the pros and cons of PVC and polyolefin shrink wrap materials before choosing either one. It's always advisable to discuss your requirements with your supplier, who can help you make an informed decision. If you have any questions or need help with sourcing shrink wrap materials, don't hesitate to contact us.
Overall, PVC works better for protection and strength, while polyolefin is perfect for clarity and appearance, environmentally-friendly issues, and value for money.
