Downstream process integration

• EVA base is melt-blended with tackifiers, plasticizers, and stabilizers, pelletized or extruded, then used in block, stick, or pellet hot melts for application via roller, spray, or nozzle

Final product types

• Packaging case and carton sealants
• Nonwoven hygiene adhesives (diapers, sanitary pads)
• Bookbinding melts
• Furniture assembly bonding agents

3. Cable and Wire Insulation Compounds

Cable compound producers rely on this grade of EVA to manufacture insulation and jacketing materials for low and medium-voltage wires. The resin supports tight property windows needed for flame retardance, flexibility, and electrical performance.

• Sports shoe midsoles
• Beach sandal footbeds
• Lightweight slippers
• Work boot outsoles

5. Film and Sheet Extrusion for Packaging

Flexible packaging manufacturers incorporate this EVA for blown and cast film processes, targeting applications where sealing, impact softness, and puncture resistance are critical. By varying thickness and blend ratios, they address both shrink and stretch characteristics required by food and medical packaging sector clients, while keeping migration and extractables under regulatory limits.
