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.

A method of handling and cooking a contents in a zippered cook-in-bag pouch, comprising: providing a pouch body having a mouth and a zipper comprising a profiled extruded plastic structure having a pair of complementary zipper strips having reclosably interlockable profiles and the strips being attached permanently to said pouch in closing relation to said pouch mouth; forming said pouch body and zipper from material which will withstand without deterioration at least a boiling heat temperature during a cooking procedure to which the pouch and the zipper may be subjected when cooking the contents; placing said contents into said pouch; providing a hot melt adhesive which sets at room temperature between said profiles and thereby bonding the profiles tenaciously against separation at room temperature; providing said adhesive in a formulation which is sufficiently softenable within a temperature range of 150°F. to 197°F. for permitting manually releasing said profiles when heated within said range for opening said pouch mouth; subjecting said pouch and contents to cooking temperature and thereby releasably softening said adhesive; after said cooking temperature softening of the adhesive opening said pouch by separating said profiles; for access to the cooked contents; and while the adhesive is still tacky reclosing the zipper and permitting the adhesive to set for resealing the zipper at substantially room temperature.
