preferably still less than about 50 cc and most preferably less than 25 cc such as less than 20 less than 15 and less than 10 cc of gas per square meter per 24 hour period at 1 atmosphere and at a temperature of 73 u00b0 f at 0 relative humidity when the first film component is gas impermeable it preferably includes one or more materials that provide a substantial barrier to the passage of gas particularly oxygen therethrough suitable materials include e g vinylidene chloride copolymers saran nylon polyethylene terephthalate ethylene vinyl alcohol copolymer silicon oxides siox etc if the second film component is gas permeable it may be constructed to have sufficient gas permeability for the intended application by e g formed from a highly gas permeable material e g polymethyl pentene a chemically or mechanically altered film component e g a perforated film component or a film component of reduced thickness and combinations of the foregoing in this manner a product can be packaged shipped and stored in a controlled atmospheric state designed to maximize the shelf life of the product e g under vacuum or in a modified atmosphere with a gas impermeable upper first film component maintaining such controlled atmospheric state within the package subsequently the package can be displayed for consumer purchase in another atmospheric state that serves to enhance the appearance of the product at the expense of shelf life e g air from the surrounding environment which causes fresh red meat poultry and pork to bloom while the product remains enclosed in the same package this is accomplished by peelably removing the upper gas impermeable first film component from the package and allowing air to come into contact with the product.
