Product Description:
PVC PE PVDC Laminated Blister Film
PVC PE PVDC Laminated Blister Film is a multi-layer high-performance blister packaging material combining the forming convenience of PVC, the sealability and chemical resistance of PE, and the superior barrier properties of PVDC. This laminated structure is specifically engineered for pharmaceutical, nutraceutical, and medical device packaging requiring high moisture/oxygen barrier, excellent thermoformability, and secure sealing with aluminum lidding foil.
The PE interlayer provides enhanced seal integrity and chemical resistance, while the PVDC coating ensures long-term product stability by blocking moisture and oxygen ingress. The PVC base offers rigidity for high-speed forming on standard blister lines.
Key Benefits:
Superior moisture and oxygen barrier (WVTR ≤2.0, OTR ≤5.0)
Excellent thermoformability for deep-draw cavities (up to 12mm)
Strong seal integrity with aluminum lidding (≥25 N/15mm)
Chemical-resistant PE interlayer protects against API interaction
Compatible with high-speed blister lines (Bosch, Uhlmann, IMA)
Material composition:
● Based on the PVC rigid film or PVC/PE, then coated high barrier material PVDC, which increased 5 times compared with single-layer PVC rigid film.
● PVC PE PVDC Laminated Blister Film give higher moisture&oxygen barrier between five to ten times than plain PVC film to extend the validity.
● PVDC is the only one packaging material approved by both FDA and EU certification which can directly contact with medicine & food.
● Compared with aluminum-foil over wrapping, PVDC can protect tablet individually,save packaging costs and improve production efficiency, however once aluminum over wrap has been opened, all barrier Properties are lost. PVC/PVDC can be used in normal blister packing machines.

Key Features & Advantages
Three-Layer Engineered Structure – PVC provides forming rigidity; PE provides seal integrity and chemical resistance; PVDC provides moisture/oxygen barrier. Each layer does its job best.
Enhanced Chemical Resistance – The PE interlayer prevents direct contact between PVC (which contains plasticizers) and the drug product. Essential for lipophilic APIs that can extract plasticizers.
Superior Seal Integrity – PE-to-PE sealing (or PE-to-lidding) produces stronger, more consistent seals than PVC-based sealing. Seal strength ≥25 N/15mm – fewer leakers.
Excellent Thermoformability – PVC base allows deep draws (up to 12mm) without thinning or cracking. Works on standard blister lines without tooling changes.
High Barrier Performance – PVDC coating provides OTR ≤5.0 and WVTR ≤2.0. Suitable for hygroscopic and oxygen-sensitive drugs.
Reduced Plasticizer Migration – The PE layer physically separates PVC from the product cavity, minimizing plasticizer transfer – a key requirement for EU/FDA compliance.
Adhesive Lamination – Layers are bonded using FDA-compliant, solvent-free adhesives – no residual solvents, no odor.
PE Interlayer – The Hidden Advantage
Most blister films are just PVC + PVDC coating. The PE interlayer in this laminated structure provides:
| Benefit | How PE Helps |
|---|---|
| Plasticizer Barrier | Prevents PVC plasticizers (DEHT, ESBO, etc.) from migrating into the drug product – critical for lipophilic APIs |
| Chemical Resistance | PE is more chemically inert than PVC – resists attack from acids, alkalis, oils, and organic solvents |
| Superior Seal Layer | PE seals to PE or lidding more reliably than PVC – higher hot-tack strength, fewer leakers |
| Reduced API Adsorption | Some APIs adsorb onto PVC surfaces; PE reduces this risk |
| Lower Extractables | PE extracts fewer substances than PVC – cleaner for sensitive formulations |
| Impact Absorption | PE layer adds toughness – better drop test performance |
▸ Applications
| Application | Why This Film |
|---|---|
| Hygroscopic Drugs | Low WVTR prevents moisture absorption (e.g., effervescent tablets, probiotics) |
| Oxygen-Sensitive APIs | Low OTR prevents oxidation (e.g., vitamins, omega-3, certain antibiotics) |
| Lipophilic Formulations | PE layer prevents plasticizer migration (e.g., oily capsules, lipophilic drugs) |
| High-Value Pharmaceuticals | Reliable barrier, strong seals, fewer rejects |
| Clinical Trial Supplies | Consistent quality and barrier for blinded studies |
| OTC & Generics | Cost-effective premium protection for everyday medications |
| Medical Devices | Sterile barrier for devices requiring EtO sterilization |
| Nutraceuticals | Light-sensitive and moisture-sensitive supplements |

Q1: What is the difference between "coated" and "laminated" PVDC films?
Coated = PVDC applied directly to PVC surface. Laminated = PE interlayer bonded between PVC and PVDC via adhesive. Laminated offers better seal strength, chemical resistance, and lower plasticizer migration.
Q2: Why do I need the PE interlayer?
PE prevents plasticizer migration from PVC into the drug product. Essential for lipophilic APIs (e.g., oily capsules, lipid-based formulations). PE also improves seal strength and chemical resistance.
Q3: Can this film be used on my existing blister line?
Yes – formed at 120–150°C on standard thermoforming equipment. No tooling changes needed. We provide a sealing parameter card for your machine model.
Q4: What is the barrier performance after thermoforming?
OTR and WVTR increase slightly at cavity corners but remain within acceptable limits (OTR ≤6.5, WVTR ≤2.8). For critical applications, we recommend increasing PVDC coat weight.
Q5: Is this film suitable for child-resistant packaging?
Yes – compatible with child-resistant lidding systems. The PE interlayer does not affect CR function.
Q6: What is the shelf life of the film itself (unused)?
24 months when stored in original packaging at 15–25°C, <60% RH.
Q7: Can I get a version without PVDC (lower barrier)?
Yes – we offer PVC/PE (without PVDC) for lower-barrier applications. Ask for the "Standard PE Seal" grade.
