[0005] The cement anti-cracking packing bag provided by the utility model is mainly composed of a cement bag body, and a frosted skin layer is attached to the surface of the cement bag body. The frosted skin layer provides additional protection, which can increase the wear resistance and tear resistance of the packing bag, and may also help to improve the appearance quality of the packing bag. The anti-cracking layer is arranged on the inner side of the cement bag body, and a gas chamber is formed inside. The gas chamber is filled with gas, and the gas pressure is higher than the atmospheric pressure. This design can provide additional support for the packing bag, reduce the pressure on the packing bag when the cement hardens, and thus reduce the risk of cracking. When cracking occurs, the cement can be pressed tightly into the interior of the cement bag body due to the high gas pressure in the gas chamber, thereby reducing the possibility of cement leakage from the side.

[0006] In one possible implementation, the gas chamber is composed of a gas-tight film, the anti-cracking layer is hollow inside, and the gas-tight film is attached to the inside of the anti-cracking layer. The gas chamber is composed of a gas-tight film, which is attached to the hollow cavity inside the anti-cracking layer, ensuring the sealing of the gas chamber, preventing gas leakage, and maintaining the high pressure state in the gas chamber.

[0007] In a possible implementation, the material of the sanding skin layer is polyethylene or polypropylene, and the thickness of the sanding skin layer is 0.1-0.5 mm. The material of the sanding skin layer is polyethylene or polypropylene, both of which have good chemical corrosion resistance and flexibility. The thickness of the sanding skin layer is 0.1-0.5 mm, which can provide sufficient strength and ensure the lightness of the packaging bag.

[0008] In a possible implementation, the anti-cracking layer is composed of a multi-layer composite material including at least one plastic film and one fiber web. This structure can provide better tensile and tear resistance and enhance the overall strength of the packaging bag.

[0009] In a possible implementation, the bottom of the cement bag body is provided with a reinforcing rib made of plastic or metal and connected to the bottom of the cement bag body by heat sealing or sewing. The design of the reinforcing rib can enhance the load-bearing capacity of the bottom of the packaging bag and prevent breakage caused by excessive load. BRIEF DESCRIPTION OF DRAWINGS
