Description

Method for manufacturing bicolor bag for living aquatic animals and bicolor bag thereof Technical Field The application relates to a bag, in particular to a manufacturing method of a bicolor bag for aquatic living bodies and a bicolor bag thereof. Background Generally, by the time fish and shrimp are purchased in an aquarium, the fish and shrimp are usually shipped in transparent plastic bags. Although transparent bags facilitate the observation of the states of fish and shrimp, there are some concerns during transportation, such as: 1. the light problem is that the transparent bag allows external light to directly enter, and the fish and the shrimp can feel uneasy. Intense light or excessive light stimulation may increase the stress of fish and shrimp, especially for those species that are used to a dim or shadow environment. 2. Pressure and startle the fish and shrimp are sensitive to external stimulus, and the transparent bag allows the fish and shrimp to directly see the surrounding movement and change, thus being easy to startle. This can cause fish and shrimp to move in the bag and blow by, causing the fish and shrimp to be dizzy to death instantly, and further causing loss. To reduce this, opaque bags are often used to transport fish and shrimp to avoid these problems. However, the opaque bag cannot observe the states of fish and shrimp in the bag in real time, and has the disadvantage in use. Disclosure of Invention The application aims to provide a manufacturing method of a double-color bag for an aquatic living body and the double-color bag thereof, and the double-color bag can provide that the aquatic living body is not frightened by external light in transportation packaging. In order to achieve the above-mentioned object, the present application provides a method for manufacturing a dual-color bag for living aquatic animals, which comprises a material manufacturing step, a cutting step, a sealing step and a cutting step. The method comprises the steps of forming a hollow bicolor bag material through a bag blowing machine, dividing the bicolor bag material into a light-transmitting area and an adjacent light-impermeable area along an axial direction, cutting the light-transmitting area away from one side of the light-impermeable area along a parallel axial direction to form an opening edge, sealing two symmetrically arranged sealing lines along a direction perpendicular to the axial direction, wherein one end of each sealing line extends to be connected with the opening edge, the other end of each sealing line extends to be connected with a sealing edge of the light-impermeable area in an arc shape, and cutting the outer sides of the two sealing lines to form a first cutting edge and a second cutting edge respectively, so that the bicolor bag is manufactured. In other embodiments, in the slitting step, one end of the bicolor bag is pulled to a platform and transversely cut along the parallel axial direction by a cutter unit to cut out the opening edge of the bicolor bag. In other embodiments, each seal line has a straight section and an associated arcuate section, one end of the straight section being connected to the open side and the arcuate section being connected to the closed side. In other embodiments, the dual-color bag has a receiving space connected to the opening edge, and the two arc sections are opposite to each other, so that the bottom of the receiving space is connected to form an arc groove. In other embodiments, the length of each straight segment is greater than the length of each arcuate segment. In other embodiments, the lengths of the first cutting edge and the second cutting edge are respectively greater than the length of the opening edge. In order to achieve the above object, the present application further provides a dual-color bag for an aquatic animal living body, which has a light-transmitting area and an adjacent light-impermeable area, wherein the light-transmitting area has an open side, the light-impermeable area has a closed side, the open side and the closed side are correspondingly spaced apart, the dual-color bag for an aquatic animal living body is symmetrically provided with two sealing lines, one ends of the two sealing lines are respectively connected to the open side in an extending manner, the other ends of the two sealing lines are respectively connected to the closed side in an arc extending manner, a first cutting edge and a second cutting edge are arranged outside the two sealing lines, and the first cutting edge and the second cutting edge are respectively connected to the open side and the closed side. Thus, the present application can be automatically manufactured in large quantities by the manufacturing method, and the manufactured bicolor bags for the living aquatic animals can provide the living aquatic animals which are not frightened and damaged by the external light in the transportation package.
