Relational Production

 
 

A 3-ply corrugated cardboard production line is a basic equipment in the packaging industry, which processes a single layer of corrugated medium with one single facer to produce 3-ply cardboard composed of top liner, medium, and bottom liner. It features a compact structure, easy operation, and high production efficiency, and is mainly used for making light-duty cartons such as express boxes and e-commerce packages. This equipment is compatible with various base paper specifications and can quickly switch to produce cardboard with different flute types, making it a cost-effective choice for small and medium-sized packaging enterprises.
