Problems solved by technology

However, the express packaging bags used in the prior art generally use polyethylene, and high-density polyethylene has strong rigidity. When sharp objects are encountered, they are easily broken due to stress concentration.
And low-density polyethylene is flammable. Once a spark source is encountered during transportation, it will easily catch fire and burn the items in the packaging bag.

Abstract

The invention belongs to the technical field of packing materials and particularly relates to a courier bag material. The courier bag material comprises the following components: 35-45 parts of low-density polyethylene, 5-10 parts of high-density polyethylene, 50-55 parts of linear low-density polyethylene, 5-10 parts of mica, 3-7 parts of calcium carbonate, 1-9 parts of palygorskite, 1-4 parts of decabromodiphenyl ether, 1-5 parts of antimony trioxide, 1.5-2.0 parts of chlorinated polyethylene, 0.1-0.25 part of antioxidant, 0.1-2 parts of coupling agent and 0.3-0.8 part of zinc stearate. Compared with the prior art, by optimizing a formula of the courier bag material, the courier bag made of the courier bag material has the characteristics of high strength, puncture resistance, laceration resistance, and better heat resistance, wear resistance and flame retardancy, thus improving the security and practicability of the courier bag significantly and being widely applicable to various courier bags.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, and in particular relates to a high-strength, puncture-resistant, tear-resistant, flame-retardant and wear-resistant express bag material and a preparation method for the express bag. Background technique [0002] With the development of society and the improvement of people's living standards, more and more people choose to shop online, and people's items are exchanged more and more frequently, which makes logistics develop rapidly. During the transportation of the article, it is necessary to pack the article with a packing bag. Since the packaging bags will be subject to various impacts or collisions during the process of delivery, transportation and transshipment, in order to ensure the safety of the contents in the packaging bags, packaging bags with high tear strength are required. However, the express packaging bags used in the prior art generally use polyethylene, and high-den...
