Heat edge sealing die

The utility model relates to a heat edge sealing mould, which comprises two mould plates matched with each other, one mould plate is provided with a plurality of holes, and the other mould plate is a base plate; or a plurality of holes are formed in the corresponding positions of the two templates, and the width d between the edges of the holes and the outer edges of the templates is not less than 1mm. The die is used for carrying out heat sealing on a packaging bag, a plastic box or a plastic bowl to form a discontinuous heat-sealing frame, the discontinuous heat-sealing frame is partially provided with a gas release opening and is partially sealed, the overall bonding strength is high, when microwave or steam heating is carried out to reach certain pressure intensity, steam breaks through the discontinuous heat-sealing frame, pressure release is achieved, and the heat-sealing effect is good. Therefore, pressure balance is achieved, the potential safety hazard of package explosion caused by microwave heating
