However, when the above-mentioned plastic bags are used to hold liquids, the corners on both sides are easily damaged
More importantly, if this kind of plastic bag is used to hold shrimp seedlings, since the bottom of the plastic bag tends to close, it will cause the plastic bag to clamp the shrimp seedlings and reduce the survival rate of the shrimp seedlings.
And when the plastic bag is placed on the transport, the plastic bag will dump, which is very inconvenient

Embodiment 1
[0020] Such as figure 1 Shown, the bottom 1 of the shrimp fry plastic bag that present embodiment refers is rectangular, and the bottom 1 center of shrimp fry plastic bag is provided with central hot-pressing edge 2, and the two ends of central hot-pressing edge 2 are provided with central hot-pressing edge 2 vertical side hot pressing edge 3. When the plastic bag holds shrimp seedlings, the bottom 1 of the plastic bag will not tend to close up, so the plastic bag will not clamp the shrimp seedlings, which ensures the survival rate of the shrimp seedlings. Moreover, when the plastic bag is placed on the means of transport, the plastic bag will not be dumped, which is very convenient.
[0021] Such as figure 2 As shown, the special mold of the plastic bag for shrimp fry of the present embodiment comprises a rectangular column 10 and a sealing seat 20 symmetrically arranged on both sides of the rectangular column 10, the top surfaces of the rectangular column 10 and the seali...

The invention provides a die special for a shrimp seedling plastic bag and suitable for containing shrimp seedlings and a method for producing the shrimp seedling plastic bag. The die special for the shrimp seedling plastic bag comprises a rectangular column and sealing bases arranged at the two sides of the rectangular column, the top face of the rectangular column and the top faces of the sealing bases are all planes, and gaps are formed between the rectangular column and the sealing bases. A heat-sealing support, a heat-sealing cutter, a sealing support, a sealing cutter and an elastic device are arranged on each sealing base, the heat-sealing cutters are arranged on the heat-sealing supports, the sealing cutters are arranged on the sealing supports, and an electric heating unit is arranged in each heat-sealing cutter. A protrusion portion is arranged at the side portion of each heat-sealing support, and the protrusion portions are connected with the sealing supports through the elastic devices. The die special for the shrimp seedling plastic bag is simple in structure, an existing traditional plastic bag with the straight-line shaped bottom can be conveniently used for manufacturing the shrimp seedling plastic bag, and the die special for the shrimp seedling plastic bag has good practicality.
Description
technical field [0001] The invention relates to a special mold for plastic bags of shrimp fry and a method for producing plastic bags for shrimp fry. Background technique [0002] The bottoms of traditional plastic bags are all in the shape of a "one", which is mainly for the convenience of production, and the plastic film can be directly made of a "one"-shaped sealing machine. However, when the above-mentioned plastic bag is used to hold liquid, the corners on both sides are easily damaged. More critically, if this kind of plastic bag is used for holding shrimp seedlings, since the bottom of the plastic bag tends to close up, it will cause the plastic bag to clamp the shrimp seedlings and reduce the survival rate of shrimp seedlings. And when the plastic bag is placed on the means of transport, the plastic bag will topple over, which is very inconvenient. Contents of the invention [0003] The purpose of the present invention is to propose a kind of special-purpose mold...
