Problems solved by technology

Although this kind of packaging bag is convenient for unloading, the moisture-proof and sealing performance of the single-layer bag structure is poor. Limited by the thickness of the material, the bag body is easy to puncture or tear, resulting in air leakage or moisture.
Another Chinese patent 2014205065915 that I applied for discloses a "sewn-type double-layer composite liner packaging bag for railway transportation". Polypropylene woven fabric with good tensile strength has the

Abstract

The invention relates to packaging materials for railway transportation and specifically discloses a composite inner packaging bag with a damping airbag for railway transportation and a production method of the composite inner packaging bag. The composite inner packaging bag comprises a bag body with a feed pipe, wherein the bag body has a rectangular structure consisting of an upper sheet, a lower sheet, a left sheet, a right sheet, a front sheet and a rear sheet; a plurality of circular mounting holes are linearly formed on the upper sheet; the lower end of the feed pipe is connected in the mounting holes; the bag body and the feed pipe adopt a double-layer structure; the two sides of each of the front and the rear sheets are communicated with the triangular damping airbag respectively. The packaging bag adopts the double-layer structure, and is damp-proof, firm in structure, convenient to use, capable of relieving shock wave generated in the feeding process, and favorable for increasing the feeding speed.

Description

technical field [0001] The invention relates to a packaging material for container transportation, in particular to a composite railway transportation lining packaging bag with buffer airbags and a production method thereof. Background technique [0002] When transporting powder materials such as flour in containers, in order to prevent pollution and leakage, plastic bags are usually used as inner packaging materials. Chinese patent 2012200411217 discloses a "special packaging bag for powder used in container transportation". An air blowing port is provided on one side of the bag body, and an air blowing pipe extending into the bag body is provided on the air blowing port, and an air bubble belt is arranged in the air blowing pipe. , When unloading, blow air into the blowing pipe through the blowing port, which is helpful for powder unloading. Although this kind of packaging bag is convenient for unloading, the moisture-proof and sealing performance of the single-layer bag ...
