Description

Technical Field

[0001] The utility model relates to the field of melting and mixing devices, and more specifically to a raw material melting and mixing device for producing plastic packaging bags. Background Art

[0002] In the production of plastics, it is generally necessary to melt plastic particles and add other raw materials to the melted plastic solution.

For this reason, we propose a raw material melting and mixing device for the production of plastic packaging bags. Utility Model Content
