PVC (Polyvinyl chloride) is a commonly used material for blister packaging due to its excellent properties and benefits for this type of application. Here are some reasons why PVC is used for blister packaging:
Clarity: PVC has excellent transparency and clarity, making it easy to see the product inside the package. This is particularly useful for retail products that need to be displayed to customers.
Durability: PVC is a strong and durable material that can protect the product from damage during shipping, handling, and storage.
Formability: PVC is easy to mold into different shapes and sizes, making it versatile for various products.
Cost-effective: PVC is a cost-effective material compared to other materials like PET, making it an attractive choice for many companies.
Barrier properties: PVC has good barrier properties against moisture, oxygen, and other contaminants, which helps to preserve the product's quality and freshness.
While PVC has many benefits for blister packaging, it is important to note that there are also some environmental concerns associated with its use. PVC is not easily recyclable, and it can release toxic chemicals when incinerated. Therefore, companies are encouraged to consider alternative materials for blister packaging that are more sustainable and eco-friendly.
