Specifically, in order to increase the utility model discloses to the clamping-force of wrapping bag to avoid the wrapping bag when the overweight material of packing into, take place to drop. The die body is provided with a film clamping surface 11 for the film clamping block 4 to abut against, and the film clamping surface 11 is provided with a film clamping groove 12 matched with the film clamping block 4. After the film clamping block 4 is pressed into the film clamping groove 12, the packaging bag can be clamped between the film clamping block 4 and the bottom of the film clamping groove 12, and can also be clamped between the film clamping block 4 and the side wall of the film clamping groove 12.

Further, the mold body includes an upper heat-sealed end 13 and a lower heat-sealed end 14, and since the package is clamped, the deformation thereof is required to be folded between the upper heat-sealed end 13 and the lower heat-sealed end 14 so as to be clamped by the clamping film block 4. Therefore, in order to make the packaging bag more easily generate crease deformation, a plurality of suckers 6 for attracting the packaging bag are further arranged between the upper heat-sealing end 13 and the lower heat-sealing end 14, the suckers 6 provide attraction force in the horizontal direction for the packaging bag, and the suckers 6 are arranged on the first transverse sealing die 1a and the second transverse sealing die 1b, so that the packaging bag can be opened preliminarily. Preferably, the suction cups 6 are distributed on both sides of the lamination block 4.
