Lyla Lyu of Dongguan Longxingsheng argues that Longxingsheng machines help reduce labour cost. It also helps reduce rejection, add better finishing and save on glue. All these, ultimately, will lower the cost-per-box.

Lyu says Longxingsheng has already received more than 100 inquiries from Indian printers looking for a suitable solution to start a rigid box plant. “With different configurations of our rigid box machinery, we are able to help our customers start from a stable semi-automatic line with functional and stable performance to handle all kind of rigid boxes, such as slant side box, round side box, and so on. Later, when the converter starts getting more orders, we can upgrade the existing machine to be more automatic, even fully automatic,” she adds.

Rigid box tips from Lyla Lyu
Mono cartons and corrugated boxes are finished in a flat shape, and they are transported in flat shape. Rigid boxes are finished like a box. We need cardboard to make the inside box, and 157gsm or 158gsm printed cover paper.

The following is the manufacturing process:
• Most cardboard come in big sizes. We need to die-cut the cardboard in suitable sizes

• Groove or die-cut the cardboard to be foldable

• Use hotmelt tape and corner pasting machine to tape the corner

• Glue the cover paper with gluing machine, use the glued cover paper to cover the box by rigid box wrapping machine
