Greenflex EVA FL55

Versalis EVA Greenflex FL55 is a specialty ethylene-vinyl acetate (EVA) copolymer developed by Versalis S.p.A. (ENI, Italy) for co-extrusion blown and cast film, multi-layer lamination, stretch film, and high-performance food packaging. With 19% vinyl acetate, MFI 2.5 g/10 min, density 0.941 g/cm³, haze 1.5%, gloss 85%, dart impact 420 g, and brittleness < –80°C, FL55 delivers a rare combination of low fisheye purity, superior flexibility, optical clarity, and low-temperature sealability.

Greenflex FL55 is engineered for converters and packaging manufacturers who demand crystal-clear, flexible, and strong multi-layer films with reliable tie-layer performance and food-contact compliance. Its balanced polarity and flow properties make it the ideal choice for co-extrusion, lamination, and flexible food packaging operations across India’s major film and packaging clusters.

Functional Features & Technical Authority

• Low Fisheye Content: Advanced resin design ensures exceptionally clean, transparent films—ideal for premium multi-layer and barrier structures where visual clarity is critical.
• Superior Tie-Layer Performance: 19% VA delivers strong adhesion between dissimilar polymers (PE, PP, PA, EVOH), eliminating the need for additional tie-layer resins in most co-extrusion and lamination applications.
• High Flexibility & Elasticity: Outstanding elongation (560% MD, 750% TD) and tear resistance (50 N/mm TD) enable robust, flexible films that withstand stretching, handling, and repeated use.
• Excellent Optical Clarity: Haze of just 1.5% and gloss 85% ensure films are bright, attractive, and suitable for consumer-facing food packaging.
• Efficient Low-Temperature Sealability: Vicat softening at 58°C combined with high VA content allows for fast, energy-efficient heat-sealing at lower temperatures, improving packaging line speeds and reducing energy costs.
• Broad Processing Window: Compatible with blown/cast film lines and a wide range of co-extrusion partners (PE, PP, PA, barrier materials), with stable extrusion at 150–170°C.
• Food Contact & Regulatory Compliance: Certified to EU and FDA standards for food-contact plastics; compliance certificates available on request.
• Premium Italian Pedigree: Manufactured by Versalis (ENI), ensuring batch-to-batch consistency, global traceability, and technical support.

Applications

Co-Extrusion Films & Multi-Layer Laminates:

Greenflex FL55 is the benchmark for multi-layer co-extrusion films, acting as a tie-layer, seal-layer, or flexibility-enhancing layer in PE/EVA/Nylon and PE/EVA/EVOH/PE structures. Its high VA content and low fisheye ensure strong, clear, and defect-free bonds—critical for barrier films and food packaging.

Lamination Films & Stretch Films:

Ideal for lamination structures, stretch films, and shrink films, FL55’s elasticity and sealability enable packaging that conforms to product shapes, resists tearing, and seals securely at low temperatures.

Barrier Films & Food Packaging:

Used in oxygen/moisture barrier films and food-contact laminates, FL55 delivers clarity, flexibility, and reliable heat-sealing for packaging meat, cheese, snacks, and more.

General Industrial Films & Specialty Applications:

FL55 is also suited for technical films, industrial laminates, and custom film formulations where adhesion, optical quality, and flexibility are required.

Key Application Highlights:

• Multi-layer co-extrusion and barrier films
• Flexible lamination and stretch films
• Food-contact packaging and sealable films
• Technical and industrial laminates
