Pharmaceutical PVC/PVDC Transparent Rigid Sheet Technical Specifications
The pharmaceutical PVC/PVDC transparent rigid sheet combines the characteristics of PVC rigid sheets and PVDC coatings, providing extremely high barrier performance. It is widely used in the aluminum-plastic blister packaging of pharmaceutical products.
Pharmaceutical PVC/PVDC Transparent Rigid Sheet Appearance Quality Requirements
- Consistent Transparent Color: The product must have a clear, colorless appearance with no color difference to ensure visual appeal and the overall quality of the product.
- No Cracks, Scratches, Wrinkles, Holes, Precipitation, Edge Damage, or Oil Stains: The surface must be smooth and flat, with no noticeable physical defects, ensuring the packaging is visually attractive and intact.
- Neat Rolling, Clean Edges, Consistent Tension: The roll must be uniform, with even edges to prevent irregular rolls from affecting production and application.
Pharmaceutical PVC/PVDC Transparent Rigid Sheet Physical Performance Specifications
- Water Vapor Transmission Rate < 0.1g: The low water vapor transmission rate indicates excellent moisture resistance, preventing moisture from entering the packaging and keeping the pharmaceutical products dry.
- Oxygen Transmission Rate < 1.6: The low oxygen transmission rate demonstrates superior antioxidant properties, effectively prolonging the shelf life of the pharmaceutical products.
- PVDC Coating Weight Accuracy, Deviation < 1g: The coating weight is uniform, ensuring consistent quality for each sheet of packaging film, preventing uneven coatings from affecting barrier performance.
Pharmaceutical PVC/PVDC Transparent Rigid Sheet Mechanical Properties
- Flexibility, Tensile Strength, and Tear Resistance: After coating and curing, the PVDC layer not only provides high barrier properties but also retains the material's flexibility and tensile strength, ensuring the stability of the packaging film during use and its compatibility with packaging machinery.
- Tear Resistance: The cured material has good tear resistance, ensuring that the packaging does not rupture or leak during use, safeguarding the pharmaceutical products.
Pharmaceutical PVC/PVDC Transparent Rigid Sheet Chemical Performance Specifications
- Vinyl Chloride Monomer Content < 1/1, 000, 000: The very low content of vinyl chloride monomer meets strict chemical safety standards, avoiding contamination of the pharmaceutical products with harmful substances.
- Content of Easily Oxidizable Substances < 1ml: The limit on oxidizable substances ensures that no harmful chemical reactions occur during production and use, protecting the pharmaceutical products.
Pharmaceutical PVC/PVDC Transparent Rigid Sheet Microbiological Indicators
- Bacterial Count < 100: The bacterial count is kept to a very low level, ensuring the hygienic safety of the pharmaceutical packaging.
- Mold Count < 30: The mold count is within the standard, preventing moisture damage and mold growth on the packaging.
- No Detection of Escherichia Coli: Strict bacterial testing standards ensure the product is free from harmful microorganisms.
- No Abnormal Toxicity: The material is non-toxic and meets the safety requirements for pharmaceutical packaging, avoiding any potential toxic effects on the products or end-users.
Pharmaceutical PVC/PVDC Transparent Rigid Sheet Technical Features
- Barrier Properties: The addition of the PVDC coating greatly enhances the barrier properties of the pharmaceutical PVC/PVDC transparent rigid sheet. Compared to ordinary PVC, the barrier performance of PVDC-coated sheets is approximately 15 times higher, effectively preventing the transmission of water vapor and oxygen, ensuring the long-term preservation of pharmaceutical products.
- Applicable Equipment: Despite the PVDC coating, this material can still be used on standard blister packaging machines, with operation parameters and methods the same as those for ordinary PVC rigid sheets, making it convenient for use on production lines.
The pharmaceutical PVC/PVDC transparent rigid sheet offers significant advantages in moisture resistance, oxidation prevention, and barrier properties. It undergoes strict process control to meet high-quality standards, making it an ideal choice for pharmaceutical packaging materials.
