CHM Machinery | What Is Kraft Paper And Where Is It Used? A Guide For Packaging And Converting - News

Kraft paper is a strong paper commonly used for packaging, wrapping, bags, and other industrial applications. It is generally made from bleached or unbleached sulfate pulp, and different grades are produced for different end uses.

Unlike ordinary printing paper, kraft paper is mainly selected for applications where strength, handling performance, and packaging functionality are important.

What Is Kraft Paper Used For?

Paper Bags

Kraft paper is widely used to manufacture shopping bags, takeaway bags, industrial bags, and other paper packaging. Sack kraft paper is specifically classified for making single-wall and multi-wall sacks.

Food and Product Packaging

Kraft paper can be used as wrapping or packaging material for a wide range of products. However, the appropriate grade depends on the product and required barrier properties. Standard kraft paper should not automatically be considered waterproof or suitable for direct food contact.

Corrugated Packaging

Kraft liner is used as a facing material in corrugated boxes and other fiber-based containers. It can be combined with fluting medium to produce corrugated board for transportation and protective packaging.

Wrapping and Industrial Applications

Kraft wrapping paper is also used for wrapping products, protecting surfaces, and other industrial packaging applications. Different grades can be selected according to basis weight, strength, surface requirements, and converting process.

What Should You Consider When Buying Kraft Paper?

The right kraft paper is not determined by color alone. Buyers should consider:

For converting companies, roll dimensions and paper specifications are particularly important because they directly affect slitting, sheeting, printing, and packaging efficiency.

Basis weight (GSM)

Roll width and diameter

Tensile and tear strength

Surface characteristics

Moisture requirements

Printing requirements

Final packaging application

Kraft Paper and Paper Converting

Kraft paper is often supplied in rolls and then converted into sheets, bags, wrapping materials, or other packaging products. This creates opportunities for manufacturers to combine suitable kraft paper grades with efficient paper converting equipment.

Choosing the right paper is therefore only the first step. Matching the paper specification with the correct converting process can help manufacturers achieve stable production and consistent finished products.
