Ethylene-vinyl acetate (EVA) copolymer, identified by its CAS number 24937-78-8, is a crucial component in the modern film and packaging industry. Its unique combination of properties, derived from its co-monomeric structure of ethylene and vinyl acetate, offers significant advantages over traditional polymers. For businesses looking to enhance their film products, sourcing high-quality EVA from a reliable manufacturer is a strategic decision.

EVA's Contribution to Film Properties

As a thermoplastic elastomer, EVA copolymer provides films with exceptional flexibility and toughness, even at low temperatures. This characteristic is vital for packaging applications where the film must withstand stress during handling, transportation, and storage without cracking or tearing. The white powder form of our Ethylene-Vinyl Acetate Copolymer, boasting a purity of 99.0% minimum, ensures excellent clarity and gloss when processed into films. This aesthetic appeal is important for consumer-facing packaging. Furthermore, EVA's hot-tack properties – the strength of a heat seal immediately after cooling – are superior to many other polyolefins, contributing to more robust and reliable seals on packaging equipment.
