Abstract
A method of forming a package by heat sealing a trap-printed laminate to a support member (e.g., tray). The laminate has a free shrink in each of the transverse and machine directions of at least about 10% at 200° F. and at least about 21% at 240° F. The laminate has an oxygen transmission rate of no more than about 100 cubic centimeters. The outside layer of the laminate comprises at least about 40% of one or more relatively high-melt polymers each having a melting point at least about 25° F. higher than the lowest melting point polymer of the sealant layer. The first film has an oxygen transmission rate greater than the oxygen transmission rate of the second film.
