Applications of LG Chem SEETEC EC28005 EVA in Industrial Manufacturing

LG Chem SEETEC EC28005 EVA is an ethylene-vinyl acetate copolymer specifically designed for use in technically advanced and compliance-critical industrial sectors. As a direct manufacturer, we focus on supporting proven downstream applications, enabling our clients in the packaging, footwear, cable insulation, hot melt adhesive, and solar module industries to achieve both regulatory compliance and production efficiency. The following sections detail key industrial scenarios where EC28005 EVA delivers application-specific results.

1. Flexible Packaging Film Production

Flexible packaging converters employ SEETEC EC28005 EVA for its well-controlled melt index and clarity, making it essential in multilayer co-extruded films for food and medical pouches. The material supports demanding sealing and mechanical property requirements, integrating into high-throughput blown or cast film processes where film impact strength and sealing behavior must comply with international health and safety legislation.

Industry compliance standards

• FDA 21 CFR 177.1350 (for food packaging contact)
• EU Regulation (EU) No 10/2011 on plastic materials for food
• China GB 9685-2016 (Food Contact Additive Standards)
• CFR Title 21 / GMP for food packaging

Typical usage ratio

• 10%–25% of the total polymer matrix, adjusted based on desired sealing temperature and impact resistance; higher loads increase seal flexibility, but must balance haze and mechanical strength for regulatory review.

Downstream process integration

• Directly loaded into film extruder hoppers and blended with LDPE or LLDPE for blown or cast film co-extrusion; dosing precision at the compounding stage ensures thickness uniformity and performance compliance.

Final product types

• Food-grade vacuum pouches
• Medical fluid bags and blister pack films
• Frozen food flexible wraps
• Pharmaceutical or laboratory sample bags

2. Footwear Injection Molding Compounds

Shoe sole manufacturers use EC28005 EVA in thermoplastic formulations to deliver required low-temperature flexibility, elasticity, and resilience for midsole and outsole components. The resin provides reliable cell structure and comfort performance in both direct injection and compression-molded footwear applications, while meeting quality and environmental protocols for global market distribution.

Industry compliance standards

• EN ISO 20344/20345 (Safety Footwear, Test Methods and Requirements)
• REACH Regulation (EC) No 1907/2006 (SVHC and restricted substances control)
• California Proposition 65 (chemical exposure limits)
• SGS Physical & Chemical Property Validation

Typical usage ratio

• 35%–65% of the total compound; adjusted based on durometer, density, and expansion required, with higher content boosting foam softness and rebound under repeated stress.

Downstream process integration

• Added at the extrusion and pelletizing phase for masterbatch production or directly dosed into injection molding machines alongside blowing agents, colorants, and crosslinking agents for cell structure control during molding.

Final product types

• Sports shoe midsoles (running, tennis, basketball)
• Casual shoe outsoles
• Safety boots
• Children's footwear

3. Low-Voltage Cable Sheathing and Insulation

Wire and cable producers turn to EC28005 EVA to impart flexibility, dielectric strength, and stress crack resistance in the manufacture of insulation and sheathing layers for low-voltage power and data cables. The resin’s compatibility with flame retardants and plasticizers allows downstream processors to meet national and international electrical safety codes while improving ease of stripping and durability during end use.

Industry compliance standards

• IEC 60502-1 (Power Cables with Extruded Insulation and Their Accessories)
• UL 1581 (Reference Standard for Electrical Wires, Cables, and Flexible Cords)
• RoHS Directive 2011/65/EU (Restriction of Hazardous Substances)
• EN 50363-2-1 (Insulation Materials - EVA Compounds)

Typical usage ratio

• 10%–30% of insulation or sheath compound; varies depending on required flexibility, flame retardancy ratings, and resistance to thermal cycling.

Downstream process integration

• Pre-mixed into cable compounding extruder along with fillers, stabilizers, and flame retardants; the formulation is then pelletized and fed into continuous cable extrusion lines for wire coating.

Final product types

• Building wire insulation (up to 1 kV)
• Flexible appliance cords
• Instrumentation and control signal cables
• Automotive low-voltage wire harnesses

4. Hot Melt Adhesive (HMA) Formulations

Formulators of hot melt adhesives specify EC28005 EVA for its balance of cohesive strength and open time, making it essential for packaging, bookbinding, and product assembly adhesive systems. The resin’s property profile supports blending with tackifiers, waxes, and stabilizers to achieve specific melt point and adhesion criteria as required by downstream converters in automated equipment lines.

Industry compliance standards

• FDA 21 CFR 175.105 (Adhesives – Indirect Food Additives)
• EU Regulation (EC) No 1935/2004 (Materials and Articles Intended to Come into Contact with Food)
• ISO 9001:2015 (Quality Management Systems for Adhesives Manufacturing)
• ASTM D906/D1002 (Peel and Shear Strength Test Methods)

Typical usage ratio

• 20%–50% of total adhesive mass; the proportion is tuned based on viscosity, open time, and bond strength target for packaging substrates, with lower percentages in bookbinding or non-food applications requiring a harder set.

Downstream process integration

• Dry-blended at the premixing stage with tackifiers and wax modifiers; compounded in hot melt tanks or extruders before direct transfer to hot melt application lines such as slot die or roll coaters.

Final product types

• Carton and case sealing adhesives
• Spine adhesives for paperback bookbinding
• Product assembly adhesives for hygiene products
• Label adhesives for logistics and retail use

5. Photovoltaic (PV) Module Encapsulation Sheets

Solar panel manufacturers rely on EC28005 EVA for producing encapsulant films that protect photovoltaic cells from environmental degradation, moisture, and mechanical stress over long operational lifespans. The material offers optical clarity and controlled crosslinking capability, which is essential for lamination lines operating under stringent temperature and pressure schedules to assure long-term solar output and module safety.

Typical usage ratio

• 100% layer for encapsulation sheets; modification with dedicated crosslinking enhancers or UV absorbers as needed for panel weatherability, subject to the ratio defined by cell type and lamination profile.

Downstream process integration

• Extruded or calendared into sheets, then co-laminated over PV cells during module assembly; formulations include crosslinking agents that activate during autoclave or lamination at 140–160°C, bonding glass and cell surfaces.

Final product types

• PV module encapsulation films
• Backsheet protective layers
• BIPV (building-integrated photovoltaic) film laminates
