    • 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.
    • 一种拉链袋式小袋和方法,其中袋和口袋口体上的成型挤出塑料拉链结构由材料形成,该材料将基本上不会损坏袋内的内容物可能经受的最大烹饪热量, 烹饪内容。 两个型材之间的一套热熔胶可以在室温下牢固地分离型材,使其不会分离。 粘合剂在基本上高于室温但接近烹饪温度的温度下可充分软化,以释放用于打开袋体的轮廓。 当粘合剂温度降低到粘合剂的可软化温度以下时,粘合剂相对于分离的轮廓可设置成非粘性状态,使得拉链然后可以随意地重新闭合并打开,而没有粘合剂干扰。
