Kraft paper is the most used material in the packaging products. It is a high strength paper, ideal as a cost-effective solution for a wide range of packaging and stationery projects. Kraft paper can be coated or laminated to improve its barrier properties and provide additional strength. When wet, this type of paper can retain a third of its dry strength and can be used in high humidity conditions.
How it is made and why it is better than regular paper?
Kraft paper products are made using the Kraft process, which, like other paper production methods, involves the chemical conversion of wood into wood pulp. The structural components in the wood are lignin and cellulose. Lignin is separated from the cellulose by cooking woodchips in a “white liquor” made of sodium sulfide and sodium hydroxide. They break them apart, leaving the solid wood pulp and a “black liquor”. The wood chips have now been turned to a pulp and are screened to remove any larger pieces and can then be formed into various paper products.
Unlike other methods, it can use all types of wood, including resinous pine and bamboo, which are left out of traditional paper making processes. Additionally, since nearly all the chemicals used in the process are recovered and reused, it is a self-sustaining method.
Salient features and Applications
Strong and durable, so can be used for protective packaging.
All the chemicals used in the manufacturing and by-products can be used again or can be used in other manufacturing purposes, hence environment friendly.
With the addition of a thin coating, makes it moisture resistant.
Very economical alternative to other available paper.
