[0002] With the rapid development of society, electronic devices are becoming more and more common, and the application scope of lithium batteries is becoming more and more extensive. Now many lithium battery raw materials, namely lithium battery powders, are packaged and sold. Due to the characteristics of lithium batteries, if they are not vacuum packaged and exposed to the air for a long time, the lithium battery powder materials will be oxidized and affect the normal operation of the lithium battery. Therefore, in actual production, it is necessary to use battery powder bags for vacuum packaging.

[0003] However, the existing battery powder bags have low strength during use, which makes them easy to break during packaging and transportation, which not only causes leakage of powder materials, but also causes the powder materials to oxidize due to long-term contact with air, thus seriously affecting the packaging safety of battery powder materials.

[0013] Optionally, the reinforcement layer is plant fiber modified by ethylation.

[0014] By adopting the above technical solution, the ethylated modified plant fiber is used to strengthen the PE composite material layer, so that the strength of the PE composite material layer is higher.

[0015] Optionally, the PE inner film layer, the aluminum-plated layer, the reinforcement layer and the PE outer film layer are bonded together by a vinyl polyurethane adhesive layer.
