SURLYN™ 1601 – Surlyn Ionomer Resin for Blown Film & Flexible Packaging

SURLYN™ 1601 is a sodium-based Surlyn ionomer resin from Dow, developed for high-performance sealant applications in flexible packaging. Processed through blown film, cast film, and sheet extrusion, it is widely used in demanding packaging formats such as processed meat and cheese packaging, pouches, sachets, and medical device forming webs. SURLYN™ 1601 delivers an outstanding combination of clarity, toughness, and abrasion resistance, along with strong oil barrier properties and excellent flex-crack resistance — making it a reliable choice where seal integrity and optical performance are equally critical. It complies with FDA Regulation 21 CFR 177.1330(a) for food contact applications.
