Packaging is one of the most crucial factors that influence all types of businesses. Corrugated box has emerged as the most preferred packaging material for any kind of shipment. The sustainability of corrugated box packaging in different businesses is due to its high strength, durability and eco-friendly nature.
What is corrugated box?
Unlike traditional cardboard box, corrugated box consists of three layers of thick layers of cardboard. The outer two layers are flat and called liners. The middle layer is wavy and called fluted layer. The two liners and the fluted layer are glued together to form corrugated cardboard to provide different strength and protection. They are available in different shapes and sizes.

What are the steps involved in manufacturing corrugated box?
Pine trees are widely grown due to its fast-growing properties and are used as raw material for corrugated cardboards. Mostly used and recycled cardboards are used as raw material for pulp. A corrugated cardboard can be recycled for seven to eight times. After sometime the cardboard fibres lose its strength for further recycling. At this time pine trees are cut down and transported to the pulp mill.
Here is the main life cycle involved in finished corrugated box –
- Pulping to form kraft paper
Here, the recycled cardboards or the tree trunks are cut into chips and mixed with chemicals to convert them into fibrous pulp. This pulp is then machined into kraft paper under high compressive strength.
- Making thick flaps and corrugated layer
Few sheets of kraft papers are joined and pressed together to form thick flaps for the outer liner layers of the box. Another roll of kraft paper is fed into corrugated machine to make the middle or fluted layer. High-strength glue is used to join the liners by sandwiching a fluted cardboard. It is then cut into different required shapes and sizes and joined together to form corrugated boxes.
These corrugated boxes are ready for sell to different industries like food, shipping, automobile and pharmaceutical industries.
- Recycling
After usage, the corrugated boxes are collected from different sources. It is again treated with water and chemicals to remove stains and colors and few amounts of virgin fibres are mixed with them to form pulps. The manufacturing process continues as usual to make corrugated finished boxes.
