Clear PVC EVOH PE Film for Capsule Blister Packaging
In the pharmaceutical and nutraceutical industries, protecting sensitive active ingredients from environmental degradation is paramount. Clear PVC EVOH PE Film for Capsule Blister Packaging has emerged as the definitive high-barrier material engineered specifically for capsule preservation. By combining the structural rigidity of PVC, the unmatched gas-blocking power of EVOH, and the superior sealing capabilities of PE, this co-extruded film ensures that your capsules remain potent, stable, and visually flawless from the production line to the consumer's hands.
Technical Architecture & Material Synergy
Unlike standard mono-films or cheaply laminated structures that risk peeling apart, this advanced film utilizes high-performance tie layers to fuse three distinct materials into a unified, high-integrity barrier:
PVC (Polyvinyl Chloride) - The Rigid Matrix: Forms the outer layer, providing excellent mechanical strength, stiffness, and effortless thermoformability. It allows capsule cavities to be formed sharply and precisely without cracking or collapsing.
EVOH (Ethylene Vinyl Alcohol) - The Oxygen Fortification: Positioned safely in the core, this ultra-thin layer acts as an absolute shield against oxygen, moisture, gases, and volatile aromas, preventing oxidation and premature degradation of capsule contents.
PE (Polyethylene) - The Hermetic Sealant: Serving as the product-contact layer, the PE film delivers a wide thermal sealing window, creating a perfect, leak-proof bond with aluminum lidding foils at optimized temperatures.
Solving Critical Sourcing & Production Challenges
Procurement managers and pharmaceutical packaging engineers often face strict quality hurdles when dealing with sensitive capsule formulations. Selecting our Clear PVC EVOH PE Film for Capsule Blister Packaging directly eliminates these common manufacturing pain points:
Prevention of Capsule Brittleness & Softening: Gelatin and vegetable-based (HPMC) capsules are highly sensitive to moisture migration. The multi-layer barrier locks in the precise moisture equilibrium required, preventing capsules from becoming brittle and cracking, or absorbing ambient humidity and turning sticky.
Zero Delamination and Zero Micro-Leaks: Our co-extrusion technology ensures the film behaves as a single body during high-speed blister machine runs. It eliminates the risk of layer separation (delamination) during the deep-draw forming of larger capsule sizes (such as #00 or #000).

GMP-Compliant Manufacturing & Quality Control
Pharmaceutical packaging demands impeccable hygiene and strict regulatory compliance. Our production ecosystem is built to satisfy the most stringent international audits:
Class 100,000 Cleanroom Production: The entire extrusion, slitting, and winding process takes place in a strictly controlled, dust-free environment to eliminate any risk of foreign particulates, black spots, or microbial contamination.
100% Automated Optical Inspection: High-speed camera inspection systems scan the film continuously on the line, instantly detecting and marking any microscopic pinholes, gels, or gauge deviations.
Full Regulatory Compliance: We provide a comprehensive documentation pack for every batch, including FDA DMF (Drug Master File), SGS, RoHS, and ISO 15378 (Primary Packaging Materials for Medicinal Products) certifications, ensuring seamless validation for your QA department.
Advanced Export Packaging & Traceability
To guarantee that your film rolls arrive at your facility free of contamination or physical warping after long-distance ocean transit, we employ a multi-layered pharmaceutical-grade shipping protocol:
Hermetic Inner Wrap: Each roll is vacuum-sealed in an anti-static PE bag along with active silica gel desiccants to prevent any moisture ingress during shipping.
Suspension Core Packing: Rolls are suspended via heavy-duty end plugs inside reinforced wooden crates or on robust pallets. This ensures the film surface never touches the ground, entirely preventing flat spots or edge damage.
End-to-End Batch Traceability: Every individual roll is barcoded with a unique Lot Number, linking it directly back to the raw material batches, production parameters, and cleanroom operators involved.

In the modern global food supply chain, maximizing shelf life without relying on chemical preservatives is a top priority for brand owners and food processors. High Barrier PP EVOH PE Film for Retort & Thermoforming Packaging has established itself as the premier choice for demanding food and sterilization applications. This multi-layer, co-extruded structures fuses the exceptional thermal resistance of Polypropylene (PP), the absolute gas-blocking performance of Ethylene Vinyl Alcohol (EVOH), and the low-temperature seal integrity of Polyethylene (PE) to deliver an uncompromised packaging solution.
Technical Composition & Advanced Co-Extrusion Technology
Unlike standard flexible laminates that fail under high thermal loads, our film uses precision co-extrusion technology to bond functional polymers without chemical adhesives, ensuring maximum safety for direct food contact:
PP (Polypropylene) - The Thermal & Mechanical Anchor: Positioned as the outer layer, PP provides the structural strength, puncture resistance, and vital thermal stability required to withstand rigorous high-temperature retort and pasteurization processes.
EVOH (Ethylene Vinyl Alcohol) - The Superior Gas Barrier: The specialized core layer acts as a flawless barrier against oxygen, vapor, organic aromas, and external contaminants, locking in product freshness and preventing flavor degradation.
PE (Polyethylene) - The Low-Temp Hermetic Seal: The inner product-contact layer offers a broad sealing window with excellent hot-tack properties, guaranteeing an airtight, leak-proof seal even on high-speed automated packaging lines.
