Description

Technical Field

[0001] This utility model belongs to the field of packaging bag technology, and in particular relates to a gypsum transport packaging bag with good waterproof properties. Background Technology

[0002] A waterproof gypsum transport bag is designed to protect gypsum from moisture or water during transport, as gypsum is prone to clumping, hardening, or losing its original properties when exposed to water.

[0003] According to the publicly disclosed pallet-free packaging bag (Publication No.: CN 107521866 A), the packaging bag body has a feed inlet in the upper middle and a discharge outlet in the lower middle. Reinforced lifting straps are located at the upper corners of the packaging bag body. Rectangular insertion channels are located on the two parallel bottom edges of the packaging bag body, with the two channels on the same horizontal line. Hollow inserts are installed within these channels, which are located inside the packaging bag body. Plaster is packed inside the packaging bag. During transportation, it is necessary to prevent moisture intrusion to avoid damage to the plaster. The coordination between the aforementioned lifting straps, feed inlet, and other components is insufficient to prevent moisture from entering the packaging bag, making it difficult to provide mechanical protection, waterproofing, and moisture resistance. The intermediate layer blocks moisture but fails to form a seal, providing strong waterproofing and moisture-proofing functions, which requires improvement. Utility Model Content

The middle layer 42, the inner layer 43, and the auxiliary layer 44 are all provided on the inner wall of the packaging bag body 1.

[0027] The outer layer 41 is located between the packaging bag body 1 and the middle layer 42. The interior of the outer layer 41 includes waterproof paper and coated paper. This layer is designed to provide external waterproof protection and prevent the penetration of external water sources such as rainwater and moisture.

[0028] The intermediate layer 42 is located between the inner layer 43 and the outer layer 41. The interior of the intermediate layer 42 includes a moisture-proof film or aluminum foil layer. The inner layer 43 is located between the intermediate layer 42 and the auxiliary layer 44. The interior of the inner layer 43 includes a PE film or a plastic film. The design of the intermediate layer 42 helps to isolate moisture in the air and prevent moisture from entering the packaging bag.

[0029] The auxiliary layer 44 is located between the inner layer 43 and the packaging bag body 1. The interior of the auxiliary layer 44 includes an anti-silver ion coating. The design of the auxiliary layer 44 helps to prevent the lapis lazuli from becoming moldy or contaminated due to moisture or other external environmental factors, thus enhancing hygiene protection.

[0030] The packaging bag body 1 has a packaging fixing component 3 on its side. The packaging fixing component 3 includes a compression strip 31, the side of which is fixedly connected to the inner wall of the packaging bag body 1. A sealing strip 32 is fixedly connected to the inner wall of the packaging bag body 1. A pleated connecting strap 33 is provided on the side of the packaging bag body 1. A horizontal strip 34 is fixedly connected to the side of the packaging bag body 1. An elastic strap 35 is fixedly connected to the side of the horizontal strip 34. A tightening strap 36 is fixedly connected to one end of the elastic strap 35. A compression block 37 is fixedly connected to one end of the tightening strap 36. A fixing block 38 is fixedly connected to one end of the tightening strap 36. By wrapping the packaging bag body 1, the plaster is filled inside the packaging bag.

[0031] Two fastening straps 36 and two telescopic straps 35 are provided and are symmetrical to each other along the vertical central axis of the packaging bag body 1. The fixing block 38 is located on the displacement trajectory of the squeezing block 37. The provision of two fastening straps 36 helps to pack the plaster more tightly and prevent leakage.

[0032] The sealing strip 32 is located on the side of the extrusion strip 31. There are two pleated connecting strips 33, which are symmetrical to each other along the vertical central axis of the packaging bag body 1. The pleated connecting strips 33 are designed to facilitate the packaging bag to pack the plaster for transportation.

[0033] A specific application of this embodiment is as follows: In this application, the outer layer 41, middle layer 42, inner layer 43, and auxiliary layer 44 of the waterproof protection component 4 provide waterproof protection for the packaging bag. The outer layer 41 includes waterproof paper and coated paper, which can provide external waterproof protection, prevent rainwater, moisture, and other external water sources from penetrating, enhance the pressure resistance and wear resistance of the packaging, prevent the packaging bag from being damaged during transportation, and have a certain mechanical strength to withstand external physical impacts. The middle layer 42 includes PE film and plastic film. The middle layer 42 serves as a moisture-proof layer, which isolates moisture in the air, prevents moisture from entering the packaging bag, provides an additional protective layer, enhances waterproof and moisture-proof capabilities, and prevents moisture from affecting the quality of the gypsum inside the bag. Sometimes an aluminum foil layer can be used to further prevent the penetration of moisture and oxygen, enhancing the waterproof and moisture-proof capabilities. The auxiliary layer 44 provides moisture protection and further protects the gypsum. Its interior includes an anti-silver ion coating, which prevents mold or contamination of the gypsum due to moisture or other external environmental factors, enhancing hygiene protection. During transportation, it acts as a buffer against impacts or compression, preventing the gypsum bag from being crushed or broken. The inner layer 43 includes a PE film and a plastic film, forming a completely sealed inner layer 43 that effectively prevents moisture and air intrusion, providing the strongest waterproof protection. The plastic film has high sealing and tensile strength, ensuring the gypsum is not affected by the external environment. Thus, the outer layer 41 provides mechanical protection to the packaging bag, offering waterproof and moisture-proof protection; the middle layer 42 blocks moisture; and the inner layer 43 forms a seal, providing strong waterproof and moisture-proof functions. The auxiliary layer 44 enhances antibacterial effects and cushions and protects the gypsum. The extrusion strip 31 is pressed into the sealing strip 32 to seal the entrance of the packaging bag, forming the first layer of waterproof sealing. For the second layer, the tightening strap 36 is pulled, and the two straps are used to wrap around the packaging bag, securing it tightly. Finally, the extrusion block 37 is used to press into the fixing block 38, thus securing the packaging bag and preventing plaster from falling out during transportation. By using multiple layers of sealing at the entrance of the packaging bag, such as the combination of the extrusion strip 31 and the tightening strap 36, the bag's adaptability to external climates is significantly improved. The highly sealed packaging bag prevents plaster from being exposed to air and moisture, thus maintaining its original dry state and preventing leakage during transportation. The waterproof packaging bag, through its multiple sealing design, ensures the safety of the packaging bag during transportation. Even in rain or other severe weather, the packaging bag will not be damaged or leak, preventing plaster loss or leakage and ensuring the safety and integrity of the packaging bag during transportation.
