When it comes to packaging, choosing the right material is crucial to ensure the safety and quality of the product. PVC (polyvinyl chloride) has been a popular choice for packaging due to its low cost and versatility. However, in recent years, PVDC (polyvinylidene chloride) has emerged as a better alternative to PVC. In this article, we will explore why PVDC is a better choice than PVC for packaging.
- Barrier Properties
PVDC has superior barrier properties compared to PVC. It is highly resistant to moisture, oxygen, and other gases, which makes it an ideal choice for packaging products that require a long shelf life. PVC, on the other hand, has poor barrier properties and is prone to permeation, which can lead to spoilage and contamination of the product.
- Safety
PVDC is a safer choice than PVC for packaging. PVC contains phthalates, which are harmful chemicals that can leach into the product and pose a risk to human health. PVDC, on the other hand, is free from phthalates and other harmful chemicals, making it a safer choice for packaging food and other products.
- Environmental Impact
PVDC has a lower environmental impact than PVC. PVC is a non-biodegradable material that can take hundreds of years to decompose, leading to environmental pollution. PVDC, on the other hand, is a more sustainable choice as it is biodegradable and can be recycled.
- Aesthetics
PVDC offers better aesthetics than PVC. It has a high gloss and clarity, which makes it an ideal choice for packaging products that require a high-end look and feel. PVC, on the other hand, has a dull and opaque appearance, which can detract from the product's visual appeal.
In conclusion, PVDC is a better choice than PVC for packaging due to its superior barrier properties, safety, lower environmental impact, and better aesthetics. As consumers become more conscious about the safety and sustainability of the products they purchase, PVDC is likely to become the preferred choice for packaging in the future.
