ABSTRACT:
A zippered cook-in-bag pouch and method wherein the pouch and a profiled extruded plastic zipper structure at the mouth of the pouch body are formed from material which will withstand substantially without deterioration maximum cooking heat to which contents within the pouch may be subjected when cooking the contents. A set hot melt adhesive between the profiles bonds the profiles tenaciously against separation at room temperature. The adhesive is sufficiently softenable at a temperature substantially above room temperature but near the cooking temperature, for releasing the profiles for opening the pouch body. The adhesive is settable to a non-tacky state in respect to the separated profiles when the adhesive temperature drops below the softenable temperature of the adhesive so that the zipper can then be reclosed and opened at will without adhesive interference.
