Degradable breathable multilayer film with improved properties and method of making same |
摘要 |
A multilayer film includes a plastic layer and an elastomeric layer. The plastic layer can contain a co-polyester of terepthalic acid, adipic acid and butanediol, and the elastomeric layer can contain a polyurethane elastomer. The plastic layer and/or the elastomeric layer can contain filler particles, and may be present as a bilayer laminate. The plastic layer and a filled elastomeric layer can also be combined with an unfilled elastomeric layer to form a tri-layer laminate. The multilayer films can provide breathable films with improved degradability, stretchability and recoverability, and tactile feel.
