Application cases of nanocellulose in the packaging field

Nanocellulose is an ideal material in the packaging field due to its high strength, low density and biodegradability. The following are some practical applications of nanocellulose in the packaging field:

1. Food packaging

• Case: Nanocellulose Packaging at Finland VTT Technology Research Center
Finland VTT Technology Research Center develops food packaging materials based on This packaging not only has high barrier properties, but can effectively prevent oxygen and moisture from entering the food, but also extend the shelf life of the food. The technology has been applied in the packaging of fruits and vegetables, reducing food spoilage and waste.nanocellulose .

• Case: Nanocellulose Coating
Some food packaging companies in Japan are using nanocellulose as the inner coating of food packaging to replace traditional plastic coatings. This coating is not only environmentally friendly, but also has good waterproof and oil-resistant properties. It is widely used in fast food packaging boxes and paper food bags.

2. Biodegradable plastic alternatives

• Case: Stora Enso’s Degradable Nanocellulose Packaging
Stora Enso is a world-renowned pulp and paper company that has developed a nanocellulose-based biodegradable packaging material for use in Alternative plastic packaging. This material has excellent mechanical properties and environmentally friendly properties and has been used in packaging of some electronic and consumer products.

• Case: Danimer Scientific and Nanocellulose Composites
Danimer Scientific in the United States has developed the technology to combine nanocellulose with its bioplastics to enhance the mechanical properties and degradation speed of packaging materials. This material is used in disposable beverage cups, tableware and other food packaging to replace traditional plastic products.

3. High barrier performance packaging

• Case: CelluForce and High Barrier Nanocellulose Films
CelluForce is a Canadian company focusing on the production of nanocellulose . They worked with packaging manufacturers to develop a high barrier nanocellulose film for food and pharmaceutical packaging. This film can effectively prevent the penetration of oxygen, carbon dioxide and moisture, making it an ideal material for products with high demand for packaging airtightness, such as coffee, snacks and pharmaceutical packaging.

4. Composite packaging materials

• Case: UPM's Nanocellulose Composite Materials Packaging
UPM is a Finnish biochemical company dedicated to developing biomaterial-based packaging solutions. They launched packaging products that combine nanocellulose with other biomaterials. Not only are these composites high-strength and lightweight, but they are completely degradable and have been used in packaging boxes for luxury and electronic products.

• Case: Nanocellulose and PLA composite
In some bio-based packaging materials, nanocellulose is combined with polylactic acid (PLA), which enhances the strength and toughness of PLA, making it more suitable for packaging applications. For example, in beverage bottles, cosmetic packaging containers, etc., nanocellulose composites have demonstrated their potential to replace petroleum-based plastics.

5. Smart packaging

• Case: Nanocellulose intelligent packaging
In the field of intelligent packaging, nanocellulose also has certain application potential. For example, some research institutions are developing nanocellulose-based sensor materials for intelligent monitoring of food packaging. These materials can detect changes in gas composition in the packaging, helping consumers judge the freshness of food, thereby reducing food waste.

6. Recyclable packaging materials

• Case: Nanocellulose Paper Packaging
Some paper packaging manufacturers are using nanocellulose to enhance the strength and moisture resistance of paper to develop recyclable paper packaging materials. This packaging material is more tough than traditional paper packaging and is suitable for packaging of electronic products and household goods. It has been promoted and used in some European countries.

7. Packaging of pharmaceutical and medical supplies

• Case: Application of nanocellulose in pharmaceutical packaging .
Nanocellulose is widely used in pharmaceutical packaging due to its excellent barrier properties and biocompatibility. For example, some pharmaceutical companies use nanocellulose packaging to ensure the stability and effectiveness of drugs, especially in packaging for vaccines and biological agents.

These cases show the diversified application of nanocellulose in the packaging field. It can not only replace traditional plastics and reduce environmental pollution, but also improve the performance and intelligence of packaging materials and promote the packaging industry to develop towards environmental protection and sustainable development.
