Downstream process integration

• Fed into high-temperature mixers with tackifiers and plasticizers, then filtered, pelletized, and loaded into hot melt extrusion and application systems for final adhesive granule, block, or stick formation.

Final product types

• Hot melt adhesive sticks (industrial and consumer grades)
• Bookbinding hot melt adhesives
• Case and carton sealing adhesives
• Pressure-sensitive adhesive laminates

3. Film Extrusion for Flexible Packaging

Flexible packaging producers choose this EVA grade for its blendability and low sealing temperatures, supporting multilayer blown and cast films used in food, hygiene, and industrial sectors. The consistent gel-free quality enables stable extrusion for clear and opaque films, including applications demanding puncture resistance and reliable hermetic sealing. Our formulation support ensures compliance across regions, especially in direct food contact or pharmaceutical secondary packaging.

Industry compliance standards

• FDA 21 CFR 177.1350 (Ethylene–vinyl acetate copolymers for food contact films)
• EU Regulation (EU) No 10/2011 (Plastics for food contact – EVA suitability)
• BRCGS Global Standard for Packaging Materials
• ISO 22000 (Food safety management in packaging value chain)

Typical usage ratio

• 6%–18% (in PE film blends); the precise amount balanced for seal strength, clarity, and process stability, with higher concentrations for peelable or soft-seal films.

Downstream process integration

• Pre-blended with linear/low-density polyethylenes; dosed at hopper in blown or cast film extrusion lines; forms the sealing and sometimes the core or skin layer in multilayer films after bubble inflation and winding.

Final product types

• Lidding films for food trays
• Deep freeze and vacuum packaging films
• Hygiene product packaging (diapers, wipes wrap)
• Laminating film substrates

4. Solar PV Encapsulation Sheets

Solar energy manufacturers rely on EVA encapsulants to protect photovoltaic modules from moisture, dust, and mechanical stress. This grade's high clarity, consistent crosslinking characteristics, and process control make it particularly suited for multi-stack PV module lamination where defect-free end products and long-term performance are critical. Our technical specialists work with PV sheet producers to optimize cure cycles and mechanical strength while maintaining global renewable energy certification benchmarks.
