Description

Technical Field

[0001] The utility model relates to the technical field of packaging bags, in particular to a low-melting-point direct-throw packaging bag for butadiene rubber blocks. Background Art

[0002] Butadiene rubber is a synthetic rubber with a regular structure formed by the polymerization of butadiene. Compared with natural rubber and styrene-butadiene rubber, it has excellent cold resistance, wear resistance and elasticity after vulcanization, less heat under dynamic load, and good aging resistance. Butadiene rubber is particularly suitable for manufacturing automobile tires and cold-resistant products. It can also be used to manufacture cushioning materials and various rubber shoes, adhesive tapes, adhesive tapes and sponge rubber. After the production of butadiene rubber blocks, the butadiene rubber blocks need to be packaged. The existing packaging of butadiene rubber blocks is packaged with packaging film, but the existing packaging film of butadiene rubber blocks is over-reliant on imports, the cost of the film is high and the melting point is too high, and it cannot be directly melted into the rubber. In order to improve the use efficiency of butadiene rubber, a direct-drop packaging bag is needed, but the existing direct-drop packaging bag still has the following shortcomings:

[0003] When existing packaging bags are used, since most packaging bags are made of plastic and plastic melts at high temperatures, it is easy to produce harmful substances, which affects the processing environment and the physical and mental health of workers. As a result, butadiene rubber needs to be stripped from the packaging bags with great effort during processing, resulting in reduced practicality of the packaging bags and reduced efficiency of use.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a low melting point direct-cast packaging bag for butadiene rubber blocks is proposed. Utility Model Content

[0005] The utility model aims to provide a low melting point direct-throw packaging bag for butadiene rubber blocks to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a low-melting-point direct-throw packaging bag for butadiene rubber blocks, comprising a main bag body and a polyimide film layer, a suture fixing block is arranged on the outside of the main bag body, and an auxiliary handle is connected to the outside of the suture fixing block, air-permeable holes are opened on both sides of the main bag body, and heat seals are arranged at both ends of the main bag body, and a polyimide film layer is additionally arranged inside the main bag body, and a low-density polyethylene layer is arranged inside the polyimide film layer.

[0007] Furthermore, the number of the auxiliary handles is four, and the four auxiliary handles are symmetrically arranged on both sides of the outside of the main bag body with respect to the front center axis of the main bag body.

[0008] Furthermore, the outer side of the auxiliary handle is flush with the outer side of the main bag body, and the auxiliary handle is fixedly connected to the main bag body via a suture fixing block.

[0009] Furthermore, the heat seals are respectively arranged at two ends of the main bag body, and the main bag body is heat-sealed into one piece through the heat seals.

[0010] Furthermore, the outer dimensions of the polyimide film layer match the inner dimensions of the main bag body, and the polyimide film layer is fixedly connected to the main bag body.

[0011] Furthermore, the inside of the polyimide film layer is flush with the outside of the low-density polyethylene layer, and the inside of the polyimide film layer is tightly attached to the outside of the low-density polyethylene layer.

[0012] The utility model provides a low melting point direct-cast packaging bag for butadiene rubber blocks, which has the following beneficial effects:

[0013] 1. The utility model can avoid the situation that most packaging bags do not have relevant structures for auxiliary leverage during use when using low-melting-point direct-throw packaging bags for butadiene rubber blocks, which causes the staff to spend time and effort to carry the butadiene rubber in the packaging bags, resulting in reduced efficiency of the packaging bags. The auxiliary handles are fixed on both sides of the outside of the main bag body through the suture fixing blocks. The main bag body is provided with a leverage structure during use through the provision of the auxiliary handles, thereby saving time and effort in carrying the main bag body. At the same time, the air permeable holes on both sides of the outside of the main bag body make the main bag body have a certain air permeability, so that the water vapor inside the main bag body can be dissipated autonomously and is not easy to affect the overall quality of the butadiene rubber. The two ends of the main bag body are closed by heat sealing to avoid the scattering of the butadiene rubber after packaging, thereby further improving the overall efficiency of the packaging bag.

[0014] 2. The utility model can avoid the problem that most packaging bags are made of plastics and the plastics melt at high temperatures and easily produce harmful substances, which affects the processing environment and the physical and mental health of the workers, and causes the cis-butyl rubber to be peeled off from the packaging bag during processing, resulting in the problem of reduced practicality of the packaging bag. The polyimide film layer inside the main bag body is environmentally friendly and non-toxic as a whole, light in weight and low in melting point. The low-density polyethylene layer is arranged inside the polyimide film layer, and the low-density Polyethylene is the lightest variety of polyethylene resin. It has good softness, extensibility, electrical insulation, transparency, easy processing and certain air permeability. Low-density polyethylene will not produce toxic substances when heated. At the same time, it has a low melting point. It will melt and gradually decompose when heated. The main gases released are harmless gases such as hydrocarbons. The low-density polyethylene layer is combined with the polyimide film layer so that the packaging bag can be put together with the butadiene rubber block during rubber mixing. There is no need to peel the packaging bag. No plastic waste will be generated during use, and no harmful substances will be decomposed during processing. It is an environmentally friendly green product. BRIEF DESCRIPTION OF THE DRAWINGS
