PVC/PVDC composite sheet is a high-barrier packaging material widely used in pharmaceutical, food, healthcare, and cosmetic industries. By laminating polyvinyl chloride (PVC) with polyvinylidene chloride (PVDC), this material retains the excellent forming characteristics of PVC while significantly enhancing barrier properties against oxygen, moisture, and light.
With increasing global emphasis on packaging safety and shelf-life performance, PVC/PVDC sheets are becoming a preferred solution in international markets—particularly in South Korea's pharmaceutical and food sectors—thanks to their maturity, cost-effectiveness, and efficiency.

Performance Advantages of MC Aluminum's PVC/PVDC Composite Sheets
1. High Barrier Performance
Excellent oxygen resistance: The PVDC layer offers ultra-low oxygen transmission rates, effectively extending product shelf life and preventing oxidation.
Superior moisture resistance: Compared to single-layer PVC, the composite structure drastically improves water vapor barrier, ideal for humidity-sensitive products such as tablets and capsules.
2. Outstanding Thermoformability
Retains PVC’s inherent thermoforming benefits; compatible with automatic blister machines, offering deep drawing, crisp forming, and minimal cracking.
3. Excellent Clarity and Aesthetics
Smooth surface and high transparency enhance product display and perceived quality. Available in various colors such as blue, amber, and semi-transparent for custom visual appeal.
4. Compatible with Multiple Sealing Methods
Performs well in heat sealing with PTP aluminum foil, Alu-Plastic films, and cold forming foils, ensuring strong bonds without delamination or curling.
5. Chemical Resistance
PVDC has excellent resistance to oil, acids, and alcohols, making it suitable for a variety of pharmaceuticals and cosmetic formulations.
6. Safe and Environmentally Friendly
Free from BPA and phthalates, compliant with ROHS, REACH, and FDA regulations. Export documentation support for KFDA (Korea Food & Drug Administration) available.
7. Stable Structure, High Adaptability
Maintains excellent dimensional stability under high temperature, high humidity, or during long-distance transport, minimizing deformation or shrinkage.
8. Flexible Customization
Thickness, coating weight, color, roll diameter, slit width, and more can be tailored to meet diverse production processes and packaging needs.
