Kraft paper food packaging is widely recognised for its strength, natural appearance and environmental sustainability, making it a popular choice across various sectors of the food industry. Its unique properties stem from the raw material used – chemical wood pulp – and the manufacturing process, which preserves much of the paper’s natural fibre integrity. These factors combine to create packaging that is durable, versatile and suitable for a variety of food products. Notable features of kraft paper in this industry are:
Tensile strength and tear resistance
The kraft pulping process removes lignin while retaining long cellulose fibres, resulting in a tough yet flexible paper structure. This makes kraft paper ideal for bags, boxes, kraft food bowls and wraps used by takeaway and delivery services, as it can withstand handling and stacking, as well as potential exposure to moisture or grease. Compared with standard paper, kraft paper retains its integrity better under pressure and humidity, reducing the risk of tearing or deformation.
Natural rustic appearance
Kraft paper’s unbleached brown colour conveys authenticity and eco-friendliness, aligning with contemporary consumer preferences for sustainable, minimalist packaging. However, it can also be bleached or coated to create a white finish for a cleaner or more refined appearance. This visual flexibility enables businesses to adapt kraft paper to suit various branding styles while maintaining an environmentally responsible image.
Coatings for added resistance
In terms of functionality, kraft paper can be coated or laminated to enhance its suitability for different types of food. Applying a thin layer of polyethylene (PE), polylactic acid (PLA) or wax enhances its resistance to water and oil, making it suitable for greasy or moist foods such as pastries, sandwiches and fried snacks. Some versions are also heat-sealable, enabling the creation of secure pouches and wrappers without the need for adhesives.
Environmental advantage
Kraft paper packaging is biodegradable and recyclable, and is often produced from renewable forestry resources. Many food businesses choose kraft packaging to meet sustainability goals and respond to consumer demand for eco-friendly alternatives to plastic. Furthermore, it is possible to print on kraft paper using flexographic or offset printing, thus supporting branding with logos, designs, or product information.
In summary, kraft paper food packaging combines strength with adaptability, which makes it suitable for a wide variety of food products, from dry snacks to hot takeaways, while reinforcing a brand’s environmentally conscious image.
