LIDSTOCK LAMINATE

摘要

A packaging laminate useful as a lidstock comprises first and second films, and an image between the first and second films. The first film comprises a sealant layer forming the inside surface of the first film. The first film has a free shrink at 220 DEG F (104 DEG C)in at least one direction of at least about 7 %. The second film comprises an outside layer forming the outside surface of the second film. The outside layer comprises at least about 40 % by weight of the outside layer of one or more relatively high-melt polymers each having a melting point at least about 25 DEG F (ca. 10 DEG C) higher than the lowest melting point polymer of the sealant layer. The second film has a free shrink at 185 DEG F (85 DEG C) of no more than about 10 % in each of the machine and transverse directions. The outside surface of the first film is directly laminated to the inside surface of the second film. The first film has an oxygen transmission rate greater than the oxygen transmission rate of the second film. The laminate has an oxygen transmission rate of no more than about lOO cubic centimeters.
