In the pharmaceutical industry, the choice of packaging materials plays a crucial role in ensuring drug safety, stability, and shelf life. With advancements in packaging technology, PVC rigid sheets have gradually become one of the mainstream materials in pharmaceutical packaging, widely used in blister packaging.
Advantages of Medical-Grade PVC Rigid Sheets
Medical-grade PVC rigid films offer high transparency, allowing clear visibility of the packaged medicine, which enhances product appeal. Additionally, PVC sheets possess high mechanical strength and toughness, making them resistant to breakage and capable of effectively protecting the medicine from external impact, ensuring safe transportation and storage. Furthermore, PVC sheets exhibit excellent chemical resistance, preventing corrosion or deterioration, which makes them particularly suitable for packaging chemical drugs.
PVC Rigid Sheet vs. Traditional Packaging Materials
1. Barrier Properties
PVC Rigid Sheet: Has lower barrier properties, requiring a PVDC coating to enhance moisture and oxidation resistance, making it suitable for long-shelf-life medications.
Traditional Packaging Materials (Glass, Aluminum Foil, PE, etc.):
Glass bottles offer excellent barrier properties but are heavy and fragile.
Aluminum foil provides superior protection but lacks transparency.
Plastics like PE require multi-layer structures to meet barrier requirements.
2. Environmental Impact
PVC Rigid Sheet: May release harmful gases when burned, making recycling challenging. Due to environmental regulations, some companies are exploring alternatives such as PET and PP.
Traditional Packaging Materials:
Glass bottles are eco-friendly and recyclable, but their production consumes high energy.
Aluminum foil has high recycling value, though its manufacturing process impacts the environment.
PE and PP plastics offer better recyclability and are increasingly used in pharmaceutical packaging.
3. Production & Cost Comparison
PVC Rigid Sheet: Features a mature production process, low cost, and excellent processing performance, making it compatible with various manufacturing techniques like thermoforming and blister packaging. Due to its good heat-sealing performance, it can be combined with aluminum foil to create secure blister packaging, enhancing sealing and storage.
Traditional Packaging Materials:
Glass bottles are recyclable but energy-intensive.
Aluminum foil is highly recyclable but its production affects the environment.
PE and PP plastics are cost-effective and recyclable, leading to their increased use in pharmaceutical packaging.
4. Application Scope
PVC Rigid Sheet: Primarily used for blister packaging, suitable for solid medications, and can be combined with other materials for high-barrier packaging.
Traditional Materials:
Glass bottles are widely used for liquid formulations.
Aluminum foil is ideal for high-barrier pharmaceutical packaging.
PE and PP bottles are used for both solid and liquid medications.
