Transparent PVC/PVDC film is widely used in pharmaceutical packaging due to its high transparency and good barrier properties. Especially for blister packaging, it requires the packaging material to have excellent barrier properties to prevent the drug from being affected by moisture, oxidation or other external factors and becoming ineffective.
PVDC can be coated on PVC film to obtain high moisture and oxygen resistance, depending on the coating weight (40g/60g/90g/120g/180g). PVDC coated blister film is the most common and popular barrier film used for pharmaceutical blister packaging. PVDC coating is also the most economical way to add waterproof and oxygen resistance to PVC film. PVDC blister film has 2-layer or 3-layer specifications, called PVC/PVDC or PVC/PE/PVDC.
Advantages:
1. High barrier property: The PVDC layer can effectively prevent water vapor and oxygen from penetrating, and is particularly suitable for drugs that are sensitive to humidity and oxygen.
2. High transparency: Ensure good product visibility, making it easy for consumers to view the contents of the package.
3. Good heat sealing: Good heat sealing with aluminum foil (PTP) ensures sealing effect and prevents contamination and leakage.
4. High mechanical strength: Suitable for high-speed automated packaging production lines, not easy to break or deform.
5. Strong chemical resistance: Suitable for a variety of drugs, including tablets, capsules, soft capsules, etc.
6. Multiple specifications available: Choose different thicknesses and PVDC coating weights (40g, 60g, 90g, etc.) according to drug protection needs.
Application areas:
Pharmaceutical packaging: such as blister packs for capsules, tablets, pills, etc.
Health care product packaging: used for vitamins, soft capsules and other products.
Food packaging: Some are used for packaging of moisture-sensitive foods, such as candy or dehydrated foods.
