What is a corrugated paper plant? | Lubripedia

A corrugated paper plant is an industrial facility where corrugated cardboard is produced.
Corrugated cardboard consists of a fluted (wavy) paper layer sandwiched between one or two flat linerboards.
It is widely used for making packaging materials and shipping boxes due to its strength, light weight, and recyclability.

How a corrugated paper plant works:

The production process involves several stages that convert paper reels into sheets or boxes of corrugated cardboard.

1. Paper preparation – large rolls of kraft paper are loaded and conditioned with steam for flexibility.
2. Corrugating – one sheet passes through heated rollers to create the fluted middle layer.
3. Lamination – the fluted layer is glued between two linerboards.
4. Drying and cutting – the board passes through dryers and is cut to size.
5. Conversion – sheets are printed, folded, and glued into packaging products.

Why lubrication and maintenance are important:

Corrugated paper plants run continuously and use equipment such as corrugators, presses, conveyors, and rollers.
Lubrication is essential to:

• reduce friction and wear on bearings and chains
• ensure smooth and consistent machine operation
• prevent breakdowns caused by heat or contamination
• extend the life of high-speed rotating parts

Clean oil and grease management also support safety and reduce waste.

Applications:

• production of shipping boxes and cartons
• packaging for consumer goods, food, and electronics
• industrial and protective packaging materials
