Packaging method of formed firework

Abstract

The invention discloses a packaging method of a formed firework. The packaging method of the formed firework is characterized in that the formed firework and a thermal contraction film are included; the two ends of the thermal contraction film are open, and the formed firework is sleeved with the thermal contraction film; the two open ends of the thermal contraction film are higher than the two ends, corresponding to the two open ends, of the formed firework; and when the thermal contraction film is heated, the whole thermal contraction film is contracted, the two open ends of the thermal contraction film are tightly attached to the inner sides of the edges of the two ends, corresponding to the two open ends, of the formed firework under the action of contraction while the thermal contraction film is tightly attached to the formed firework, and finally, sealing packaging of the two open ends, corresponding to the two ends of the formed firework, of the thermal contraction film is finished through heating. The packaging method of the formed firework has the advantages that the packaging and forming speed is higher, no glue is need for gluing, the thermal contraction film is tightly and firmly attached to the formed firework, no loosening or falling off occurs, and the whole quality and attractiveness of the finished packaged formed firework are guaranteed.

Description

technical field [0001] The invention relates to the field of packaging of fireworks products, in particular to a packaging method for shaped fireworks bodies. Background technique [0002] In the prior art, the packaging of the formed fireworks body is made of paper or plastic film adhesive packaging. When packaging, the upper and lower ends of the fireworks are respectively glued and packaged, and then the periphery is glued and packaged. The packaging area used for the two ends is larger than the area of ​​the two ends of the shaped fireworks body, so when packaging the two ends of the shaped fireworks body, it is necessary to extend one end and pack it to the outer periphery of the shaped fireworks body to form a buckle, and then wrap the outer edge of the shaped fireworks body to form a buckle. The packaging will cover the buckles extending to the periphery of the formed fireworks body along its two ends and complete the packaging. With this packaging method, not only th...

[0002] In the prior art, the packaging of the formed fireworks body is made of paper or plastic film adhesive packaging. When packaging, the upper and lower ends of the fireworks are respectively glued and packaged, and then the periphery is glued and packaged. The packaging area used for the two ends is larger than the area of ​​the two ends of the shaped fireworks body, so when packaging the two ends of the shaped fireworks body, it is necessary to extend one end and pack it to the outer periphery of the shaped fireworks body to form a buckle, and then wrap the outer edge of the shaped fireworks body to form a buckle. The packaging will cover the buckles extending to the periphery of the formed fireworks body along its two ends and complete the packaging. With this packaging method, not only the packaging process is complicated, but the finished product needs to be dried after packaging, and the finished product takes a long time. Poor tightness and firmness, easy to loose and fall off, and the glued wrapping paper is also easy to wrinkle, which affects the integrity and aesthetics of the package
