In order to prepare this material, many types of papers are used and number of layers are formed to create proper material.
To start with all the papers and also other recycled cardboards are treated with very high-pressure steam so that its fiber can get softened and they are compressed to a desired thickness. With the combination of pressure and heat the material becomes durable and strong too.
During box manufacturing the necessary thickness and size of the material is chosen and cut according to size and given the proper shape and necessary bend so that proper box can be formed.
How is the quality checked?
Quality parameters are checked on the following basis –
- The type of papers used during the manufacturing of corrugated boards
- When the materials are passed throw corrugators then the box blanks are made which are pulled and tested
- The amount of moisture present is tested
- Glue strength, compression, bursting strengths are tested by using certain testers
- Flatness of the blank box is tested by wrap test
- No damage in the shape is accepted
Various types of corrugated cardboards
These boards are available as a single, double or triple wall variety. The strength of the box will be determined by the thickness of the flute.
