Abstract

The invention discloses a non-loss repeated usage package bag for pitch logistics. The non-loss repeated usage package bag comprises package bag bodies. A middle layer of each package bag body is a strengthening net, wherein the outer portion of the tail of the strengthening net is sequentially provided with brown paper, a waterproof layer and a protection layer, and brown paper, a waterproof layer and an anti-adhering layer are sequentially arranged in the strengthening net. The four edges of the two package bag bodies are connected through strengthening strips. According to the non-loss repeated usage package bag for pitch logistics, through the manner that the strengthening strips are arranged between the package bag bodies on the two sides, the sealing performance of the package bag bodies is guaranteed, and seepage is prevented; meanwhile, the double-opening type design of a filling opening and a sealing opening is adopted, and high-temperature liquid pitch filling is convenient;cooled and caked pitch is conveniently taken out later; the anti-adhering layer is arranged in each package bag body, the pitch is effectively prevented from adhering to the package bag bodies, the package bag bodies can be recycled and repeatedly utilized, and the transportation and package cost is reduced.

Description

technical field [0001] The invention relates to the technical field of logistics packaging, in particular to a non-loss reusable packaging bag for asphalt logistics. Background technique [0002] The packaging material used for asphalt was originally made of multi-layer kraft paper. High-temperature asphalt was poured into the packaging bag and solidified into an asphalt block. Leakage often occurred. Low strength, easily broken during storage and transportation. [0003] These years, constantly have the asphalt packing bag of patent report improvement, and in 1995, Chinese patent (95102960.6; 95111371.2) made packing bag with modified polypropylene or plastics braided material and improved mechanical strength. In 1997, Dalian Beida New Packaging Products Co., Ltd. applied for the Chinese patent ZL97229320.5. Hot-melt adhesive sheets were added to the four corners of the M side of the packaging bag to ensure that the packaging bag was filled with asphalt and pressed. The c...
