Pullulan is used to make bags for packaging fried foods and high-fat foods, such as ham, ham sausages and quick-frozen foods, to prevent deterioration, inhibit moisture and maintain freshness. Using pullulan in packaging can help food stay fresh and prevent spoilage, thereby extending the storage period by 4-5 times.

Pullulan is Used in Food Packaging

In the realm of food packaging, the quest for innovative materials that can enhance product safety, shelf life, and sustainability is perpetual. Among these, pullulan emerges as a versatile biopolymer with remarkable properties, offering a range of benefits in food packaging applications. Pullulan is a water-soluble microbial exopolysaccharide. It has been used as a food ingredient in the form of thickeners and stabilizers. Pullulan has been utilized in edible coatings and films for food packaging in the last years.

Understanding Pullulan

Pullulan is a naturally occurring polysaccharide produced by the fermentation of starch by the fungus Aureobasidium pullulans. It is composed of repeating maltotriose units linked by α-(1,6) glycosidic bonds, resulting in a linear, water-soluble polymer with unique physicochemical properties. The physical and chemical properties of pullulan include being a white powder with a viscosity range of 15~180mm², monosaccharide, disaccharide, and oligosaccharide content of ω≤10%, and total nitrogen content of ω≤0.05%. We can OEM customization for you according to your actual needs.

Properties of Pullulan

The properties of pullulan contribute significantly to its role in food packaging.

1. Barrier Properties: Pullulan exhibits excellent oxygen barrier properties, making it suitable for preserving the freshness and extending the shelf life of oxygen-sensitive food products such as snacks, cereals, and beverages.

2. Film-Forming Ability: Pullulan can form thin, transparent films with good mechanical strength, flexibility, and moisture resistance, making it an ideal material for food packaging applications.

3. Biodegradability: Unlike conventional petroleum-based plastics, pullulan is biodegradable and compostable, offering a sustainable alternative for reducing environmental pollution.

4. Non-toxic and Odorless: Pullulan is non-toxic, odorless, and flavorless, ensuring that it does not impart any undesirable characteristics to packaged foods.

5. Compatibility with Food Ingredients: Pullulan exhibits excellent compatibility with various food ingredients and additives, enabling the incorporation of functional compounds such as antioxidants, antimicrobials, and flavor enhancers into packaging materials.

Applications of Pullulan in Food Packaging

1. Edible Films and Coatings: Pullulan-based edible films and coatings are used to enhance the shelf life of fruits, vegetables, and bakery products by reducing moisture loss, microbial growth, and oxidation.

2. Modified Atmosphere Packaging (MAP): Pullulan films can be utilized in MAP systems to control the composition of gases (e.g., oxygen, carbon dioxide) within the packaging, thereby preserving the quality and freshness of perishable foods.

3. Sachets and Pouches: Pullulan-based sachets and pouches are employed for packaging food additives, desiccants, and oxygen scavengers, ensuring product stability and safety.

4. Single-Use Packaging: Pullulan-based single-use packaging materials, such as wrappers for individual servings of candies, mints, and chewing gum, offer convenience and hygiene while minimizing environmental impact.

5. Biodegradable Packaging: Pullulan-based biodegradable trays, cups, and containers provide eco-friendly alternatives to traditional petroleum-based plastics, contributing to the reduction of plastic waste.

Environmental Implications

In an era marked by growing concerns over plastic pollution and environmental sustainability, the adoption of biodegradable packaging materials like pullulan holds significant promise. By replacing conventional plastics derived from fossil fuels, pullulan contributes to reducing the accumulation of non-biodegradable waste in landfills and oceans. Moreover, the biodegradability of pullulan ensures that disposed packaging materials can be broken down into harmless byproducts through natural processes, minimizing environmental harm.

Future Perspectives

As consumer preferences shift towards eco-friendly and sustainable packaging solutions, the demand for pullulan in food packaging is expected to rise. Ongoing research efforts aim to further enhance the properties and functionality of pullulan-based materials, exploring novel processing techniques, additives, and composite structures. Additionally, advancements in biotechnological processes for pullulan production may lead to cost reductions and increased scalability, making it more accessible to food manufacturers worldwide.


Pullulan represents a paradigm shift in the realm of food packaging, offering a sustainable alternative to conventional plastics while meeting the diverse requirements of the food industry. With its exceptional properties, versatility, and eco-friendly profile, pullulan is poised to play a pivotal role in shaping the future of food packaging, promoting environmental stewardship and consumer well-being.
