Applications of Braskem Evateno TN2006 EVA in Industrial Manufacturing

Braskem Evateno TN2006 EVA is a linear low-density ethylene-vinyl acetate copolymer that exhibits controlled melt flow, enhanced clarity, and flexibility. As the manufacturer, we focus on the direct supply of TN2006 EVA for critical industrial segments where consistent quality, regulatory compliance, and performance are mandatory for downstream product quality and safety. Below we detail four substantial downstream application scenarios utilized by global formulators and processors.

1. Food Packaging Films

Processors utilize TN2006 EVA in the production of multilayer coextruded packaging films requiring excellent sealability and impact resistance. These films protect foods from environmental exposure and maintain shelf stability during transportation and storage. Compliance with strict food contact regulations necessitates precise resin selection and blend adjustments, particularly in high-speed blown and cast extrusion lines. TN2006 EVA enables low-temperature sealing and reduces risk of seal failure even with variable film thicknesses.

Industry compliance standards

• U.S. FDA 21 CFR 177.1350 (Ethylene-vinyl acetate copolymers for food contact)
• EU Regulation (EU) No 10/2011 (Plastic materials and articles intended to come into contact with food)
• China GB 9685-2016 (Food safety standards for additives in food contact materials)
• ISO 22000:2018 (Food safety management systems in packaging)

Typical usage ratio

• 10–20% of total polymer blend for multilayer films; adjusted according to performance target and sealing requirements
• For peelable or easy-open lids, use can increase to 25% for targeted peel strength
• Lower ratios (5–10%) when added as a modifier in conjunction with LDPE/LLDPE bases
• Ratio determined by specific application, migration limits, and local regulatory thresholds

Downstream process integration

• Direct dosing into blown or cast film extrusion lines prior to multilayer die assembly
• Melt blending with LDPE/LLDPE resins in twin-screw compounding extruders for homogeneous dispersion
• Compatibility checks for coextrusion with barrier layers (e.g., EVOH or PA) in lamination structures
• Masterbatch or minor additive integration possible for specialized requirements (antifog, slip, etc.)

Final product types

• Flexible food pouches for refrigerated or frozen foods
• Lidding films for dairy, ready meals, and snack packaging
• Vacuum bags and shrink bags for meat and cheese
• Multilayer laminates for high-barrier packaging applications

2. Photovoltaic Encapsulant Sheets

TN2006 EVA serves as a crucial raw material for solar panel encapsulation sheets, delivering controlled cross-linking, UV resistance, and excellent optical transmission. The encapsulant layer protects solar cells from moisture ingress and physical impacts while ensuring efficient light passage. Processing adjustments including cross-linking agent dosage, cure profile, and degassing protocols are critical during sheet extrusion and lamination to meet reliability and service lifetime targets commonly required by leading module manufacturers.

Industry compliance standards

• UL 1703 (Flat-plate photovoltaic modules and panels)
• IEC 61215 (Crystalline silicon PV module design qualification and type approval)
• IEC 61730 (Photovoltaic module safety qualification)
• RoHS Directive (EU Restriction of Hazardous Substances)

Typical usage ratio

• 60–80% of total sheet composition, balance with UV stabilizer, curing agent, and antioxidant package
• EVA content specifically tailored for optimal cross-linking and mechanical properties
• Adjustment for sheet thickness (0.3–0.6 mm) and weathering resistance per PV module type
• Formulation optimization based on cell efficiency and encapsulation process constraints

Downstream process integration

• Compounded with cross-linking and stabilizer additives in twin-roll calender or extruder prior to sheet extrusion
• Sheet lamination directly onto solar cells under vacuum, with controlled cure cycles (typically 140–155°C)
• Process controls for moisture, gel content, and adhesive performance in final assembly
• Integration with backsheet and glass layers in final solar module structure

Final product types

• Photovoltaic encapsulation sheets for crystalline silicon and thin-film solar panels
• Backsheet adhesives and edge sealant layers
• Flexible photovoltaic laminates for off-grid and BIPV solutions
• Encapsulated glass-glass or glass-film PV modules

3. Hot Melt Adhesive Formulations

Manufacturers incorporate TN2006 EVA into industrial-grade hot melt adhesives owing to its balanced tackiness, flexibility, and cohesive strength. Used predominantly in bookbinding, packaging, woodworking, and textile lamination, TN2006 EVA allows for rapid set adhesive systems that process at moderate temperatures. Polymeric compatibility, oxidative stability, and flow behavior under defined shear conditions need precise control for each application to guarantee consistent adhesion and end-use safety, especially for food and medical-grade packaging adhesives.

Industry compliance standards

• FDA 21 CFR 175.105 (Adhesives for indirect food contact)
• REACH Regulation (EC) No 1907/2006 (Substance registration and compliance)

• GMP Regulation (EC) No 2023/2006 on good manufacturing practice for materials intended to come into contact with food

Typical usage ratio

• 30–60% of total hot melt base, balanced with tackifier resins, waxes, and stabilizers
• Higher EVA ratio (up to 70%) for soft, flexible adhesives; lower ratio (down to 25%) for stiff, high-strength adhesives
• Adhesive composition tailored based on viscosity, setting time, and end-use performance requirements
• Ratio adjusted to substrate type and line speed in packaging or bookbinding operations

Downstream process integration

• Batch blending and pre-melting in jacketed vessels for homogenous hot melt preparation
• Direct metering and extrusion onto substrates (paper, fabric, plastic film) at process temperatures typically 120–170°C
• Integration into pressure-sensitive adhesive lines, pillow block, or drum-unloading systems according to production volume
