《The Use of PVC Film in Pharmaceutical Packaging》

 Introduction

In the field of pharmaceutical packaging, the choice of materials is crucial to ensure the safety,

I. Properties of PVC Film

PVC film is a thermoplastic material that offers several desirable properties for pharmaceutical packaging. 

1. Chemical Resistance 

2. Barrier Properties

3. Flexibility and Durability

4. Transparency

PVC film is transparent, allowing for easy inspection of the packaged drug. This is important for ensuring the quality and integrity of the product.

5. Cost-effectiveness

II. Applications in Blister Packaging

Blister packaging is one of the most common applications of PVC film in pharmaceutical packaging.

1. Structure of Blister Packaging

Blister packaging consists of a thermoformed PVC film that creates individual cavities for the drugs. These cavities are then sealed with a backing material, usually aluminum foil or paperboard. 

2. Advantages of Blister Packaging

• Visual Appeal: Blister packaging is often visually appealing, which can enhance the product's marketability. 

3. Manufacturing Process 

1. Structure of Composite Blister Packaging 

2. Advantages of Composite Blister Packaging 

• Improved Barrier Properties: The combination of PVC film and aluminum foil provides excellent barrier properties against moisture, oxygen, and light. 

• Enhanced Strength and Durability: The addition of paperboard or other backing material gives composite blister packaging increased strength and durability. 

• Customization: Composite blister packaging can be customized to meet specific packaging requirements,

IV. Other Applications of PVC Film in Pharmaceutical Packaging

1. Labels and Inserts

2. Overwraps and Shrink Wraps

3. Pouches and Bags 

V. Challenges and Considerations

1. Environmental Impact 

2. Regulatory Requirements

3. Compatibility with Drugs
