Hanwha TotalEnergies EVA E181L
Hanwha TotalEnergies EVA E181L is an advanced 18% vinyl-acetate EVA copolymer engineered for high-speed T-die extrusion coating of BOPP film, kraft paper, aluminium foil, and flexible packaging. Manufactured by Hanwha TotalEnergies (South Korea) using proprietary high-pressure tubular polymerization, E181L delivers MFI 25 g/10 min, VA 18 wt%, density 0.940 g/cm³, tensile yield 125 kg/cm² (~12.3 MPa), elongation >600%, Vicat 56°C, melting point 83°C—making it the top choice for converters running high-productivity coating lines across India.
Key Functions, Features & Specs – Technical Authority
- 18%-VA-Adhesive: 18% VA content ensures strong adhesion to BOPP, kraft paper, foil, and film substrates.
- 25-MFI-HighSpeed: Melt index 25 g/10 min enables rapid, thin-layer extrusion at high line speeds.
- Optical-Clear: Proprietary tubular process yields excellent optical clarity and low gel level for transparent coatings.
- Coating-Focused: Explicitly designed for T-die extrusion coating—distinct from foam or general film EVAs.
- Balanced-Drawability: Stable film geometry, well-balanced drawability, and neck-in for reliable production.
Detailed Applications – Where E181L Excels
Extrusion Coating for Flexible Packaging (Core)
- BOPP film coating: For snacks, bakery, and dried goods packaging—moisture barrier, breathable, and printable.
- Kraft paper lamination: For food wraps, burger wrappers, pizza boxes—moisture and grease resistance.
- Aluminium foil lamination: For flexible, printable food packaging and technical laminates.
- Multi-layer films: EVA as a heat-seal or adhesion layer in co-extruded food packaging.
Why E181L:
High MFI allows thin, uniform coatings at high speed; 18% VA ensures strong substrate adhesion; low gel level and high clarity guarantee premium film quality.
General Flexible Packaging Films
- Stand-up pouches, gusset pouches, and laminates for non-food (cosmetics, detergents, industrial goods).
- Technical films, agricultural films with EVA heat-seal layer.
Specialty & Technical Films
- Tarpaulins, industrial tarps, protective films for glass, plastic, and metal.
- Custom laminates where clarity, adhesion, and thin-film performance are critical.
Miscellaneous Coating Applications
- Cable sheathing (select cases), film-to-substrate adhesive layers, industrial bonding.
