Overwrapping machine, also known as transparent film overwrapping machine, cigarette packing machine, transparent film hexahedron folding cold packaging machine, transparent film packaging machine. This machine takes BOPP film or PVC as the packing material, and will be packaged into a three-dimensional hexahedron folding packaging equipment. Overwrapping machine was first introduced from abroad, after continuous improvement by domestic enterprises to make it meet the domestic market, now there are manual, semi-automatic, automatic models, and single box packaging and set box packaging.
