Application and advantages of kraft paper

What Kraft Paper Is

Kraft paper is a strong, durable paper made from wood pulp using the kraft process. It is known for its high tensile strength, flatness, and resistance to tearing. The paper is free from folds, wrinkles, holes, and sand, ensuring consistent quality during printing and packaging processes.

Why Kraft Paper Is Used in Packaging

Its tensile strength makes it ideal for carrying heavy or bulky items without tearing. This is especially important in food packaging, where bags must remain intact when lifted. The paper also maintains shape under stress, which helps prevent deformation during handling and transport.

Moisture Resistance and Temperature Stability

Kraft paper performs well in environments with moisture and temperature changes. It resists water absorption and maintains structural integrity during freezing and thawing cycles, making it suitable for frozen food packaging. It does not wrinkle, distort, or deform under thermal stress.

Applications in the Food Packaging Industry

Kraft paper is widely used in food packaging for items such as snacks, baked goods, and beverages. It meets the needs for convenience, portability, and protection. The material is also used in paper bags, handbags, color boxes, gift boxes, notebooks, workbooks, and envelopes.

Advantages Over Other Packaging Materials

Compared to SBS paper, kraft paper offers better strength and resistance to deformation. It provides stable heat transfer during hot pressing, high flatness, and consistent performance. The roll end is flat with no more than two joints per roll, reducing downtime and waste during production.

Environmental and Recycling Benefits

As a recyclable and biodegradable material, kraft paper supports the shift from plastic to paper in packaging. It aligns with environmental policies that restrict plastic use and promote sustainable packaging solutions. It can be recycled with other paper and cardboard products.
