A hot exhaust seal film structure comprising a printed layer, an ink layer, a glue layer and a heat seal layer from top to bottom, the ink layer is printed on the print layer, and the heat seal layer is adhered to the glue layer through the glue layer Below the printed layer, the glue layer is divided into a plurality of spaced sizing zones, and two or more venting channels are formed between the plurality of sizing zones, so that when the heat sealing layer is circulated through the venting holes Without precise positioning, at least a plurality of vent holes can be communicated with the exhaust passage, so that when the novel heat seal is mounted on the microwave food box, microwave heating can be generated through the vent hole and the exhaust passage. The vapor is effectively discharged from the inside of the microwave food container to prevent the film from being broken.一種熱排氣封膜構造，由上而下包括一印刷層、一油墨層、一膠水層以及一熱封層，該油墨層印刷在該印刷層，該熱封層透過該膠水層黏貼在該印刷層的下方，該膠水層分為多個間隔的上膠區，在多個上膠區之間形成兩條以上的排氣通道，因此在該熱封層穿設成排的排氣孔時，不需要準確定位，就能讓至少數個排氣孔正對排氣通道而與其相通，使得本新型熱封合在微波食品盒上時，透過排氣孔與排氣通道能使微波加熱產生的蒸氣有效從微波食品盒內向外排出，達到防止封膜破裂的效果。
