Specification :

Kraft paper, also known as Kraft board, is a versatile material that is widely used in the packaging industry. It is made from
chemical wood pulp and comes in a range of grades, including normal Kraft and high-strength Kraft. * Kraft paper can be either
brown or white, depending on whether it has been bleached.

Product parameter:

Here are some key aspects of the technology involved:

Material Selection: The technology starts with selecting the appropriate type of paper or paperboard for the intended food packaging application. White paperboard, also known as solid bleached sulfate (SBS), is commonly used for folding cartons, boxes, and containers. It is made from bleached chemical pulp and has a bright white appearance, making it suitable for high-quality packaging. White paper sheets or rolls may also be used for wrapping or lining food products.

Papermaking Process: The selected paper or paperboard undergoes the papermaking process, which involves pulping, refining, forming, pressing, and drying. In the case of white paperboard, the pulp may be bleached using chlorine or chlorine dioxide to achieve the desired brightness level. The papermaking process aims to produce a smooth, uniform, and printable substrate with the required strength and barrier properties for food packaging.

Coating and Surface Treatment: To enhance the appearance, functionality, and performance of white paper packaging for food, various coating and surface treatment technologies may be employed. This can include applying coatings such as clay, latex, or polyethylene to improve printability, moisture resistance, grease resistance, and barrier properties. Surface treatments such as calendaring or supercalendering may also be used to achieve a smoother finish and enhance the paper's surface characteristics.

Printing and Decoration: White paper packaging for food is often printed with branding, product information, nutritional labels, and decorative designs using various printing technologies such as offset lithography, flexography, digital printing, or gravure printing. Specialized inks, coatings, and finishes may be applied to achieve desired visual effects, including gloss, matte, metallic, or embossed finishes.

Die Cutting and Folding: Once printed and coated, the white paperboard or paper may undergo die cutting, creasing, and folding processes to create the desired shape and structure for the food packaging. Automated machinery and equipment are used to accurately cut, score, and fold the paperboard into cartons, trays, sleeves, pouches, or other packaging formats suitable for food products.

Quality Control and Compliance: Throughout the manufacturing process, stringent quality control measures are implemented to ensure that white paper packaging for food meets regulatory requirements, industry standards, and customer specifications. This includes testing for factors such as strength, durability, barrier properties, print quality, and food safety.
