MULTILAYER WEB FOR VACUUM SKIN PACKAGING WHICH IS SEPARABLE INTO PERMEABLE AND IMPERMEABLE FILMS, THE PERMEABLE LAYER HAVING A SEAL LAYER CAPABLE OF BONDING TO A SURFACE WITH A BOND STRENGTH GREATER THAN THAT OF THE TWO SEPARABLE FILMS.

摘要

A vacuum skin package for packaging fresh red meat and like articles is produced by using a composite, multilayer, oxygen barrier, vacuum skin packaging forming film in which the impermeable film can be manually separated from the non-barrier, oxygen permeable film. After the vacuum skin package is formed to enclose a fresh red meat product in a vacuum the meat will have a purplish color. Then, after storage, the impermeable film can be removed so that the remaining permeable film can admit oxygen to impart the desirable red bloom to the fresh meat. The oxygen permeable film preferably includes a core having enhanced permeation properties. The impermeable film preferably includes an EVOH layer sandwiched between ionomer layers for improved barrier properties.
