- Thickness: 40 µm (20 µm film + 20 µm EVA coating).
- Properties:
- Specific gravity: 1.12
- Equilibrium moisture content: circa 2% (23°C, 50% RH)
- Surface energy: 34-38 dyn cm⁻¹
- Areal density: 44.8 gm⁻²
- Yield: 22.32 m²/㎏
- Dynamic friction coefficient: 0.4-0.65
- Copolymer content: 14-15%
- Mechanical: Tensile strength (MD) 50-60 Nmm⁻², Elongation at break (MD) 25-45%, E-Modulus 1300-1500 Nmm⁻², Tear initiation/propagation (MD) 0.11/0.06 N
- Thermal: Linear shrinkage (MD) 1-1.5% (115°C, 10 min), Acetate/EVA softening/peak melting temperatures ~130/83°C, Acetate/EVA Vicat softening temperature ~51°C
- Chemical Resistance: Low resistance to ketones, attacked by esters, moderate to concentrated strong acids and bases. Resistant to non-polar solvents.
- Applications: Fenestration, labeling, adhesive tape, thermoforming, and over-wrapping. Suitable for microwave heating due to resistance to oils, fats, and water.
- Certifications: Home Compost certified, food contact approved.
- Processing: Suitable for thermal lamination at 90-100°C, speeds up to 75 m/min. Accepts foil blocking well. Primers/over-varnishes may be needed for overprinting and spot varnishing.
- Availability: Widths up to 1260 mm, single length roll nominally 2400 m. Coating surface can be wound to the inside or outside.
