Problems solved by technology

[0009] In the preparation process of the antistatic packaging film used for electronic packaging in the prior art, due to the incompatibility of the antistatic agent particles, it will cause uneven dispersion and serious agglomeration in the masterbatch, which will affect the antistatic performance of the film. At the same time, the layering of the masterbatch resin is caused by the problem of antistatic particle agglomeration, and its layered structure will also reduce the biodegradability of the film
