Biopolymer-based packaging combines durability and ecological innovations to meet the demands of the food industry. These solutions reduce the carbon footprint and promote sustainable resource management.
Biomaterials represent a diverse class of materials of biological or mixed origin. These materials, often derived from renewable resources such as by-products from the food industry, offer significant benefits in terms of sustainability, performance, and environmental impact, making them ideal candidates for the production of innovative and environmentally friendly food packaging.
Performance of biomaterials in food packaging includes:
- Formation of edible and biodegradable films or coatings
- Barrier properties
- Mechanical resistance
- Adaptability to processing conditions
- Thermal stability
- Biocompatibility
- Development of active functionalities
Advantages of packaging based on biomaterials:
- Reduction of carbon footprint
- Management of waste and by-products
- Biodegradability and compostability
- Conservation of non-renewable resources
- Enhancement of food safety
- Reduction of food waste
- Reduction of waste management costs
- Savings on raw materials
- Enhancement of brand image and consumer perception
Possible forms of packaging based on biomaterials:
- Films
- Trays and platters
- Pouches
- Edible packaging: Some biodegradable food packaging is edible and can be consumed along with the product they wrap. These packages are often made from food ingredients such as gelatin, chitosan, sodium alginate, or milk proteins. They offer an innovative and ecological alternative to traditional packaging.
- Intelligent packaging: These packages incorporate advanced functionalities such as freshness indicators, modified atmosphere control, tampering sensors, traceability, and authentication. By leveraging the unique properties of biopolymers, these packages proactively respond to the changing needs of consumers and the food industry.
