PACKAGE HAVING READILY PEELABLE SEAL AND PROCESS FOR FORMING SAME

摘要

An easily peelable heat seal between two sheets of cross-linkable polyolefin packaging materials is achieved by cross-linking the polyolefin material in each sheet by irradiating the sheets to a dosage level of at least 3 MR prior to heat sealing the sheets together. The easily peelable seal is especially useful where film surfaces in large flange areas are sealed together.
