Packaging plays a crucial role in the protection and preservation of products throughout the production and logistics chain. It is an essential component for industries such as food and beverage, where packaging ensures not only the safety and integrity of the product but also extends its shelf life. However, growing awareness of the environmental impacts associated with excessive use of plastic and non-sustainable materials has led to a paradigm shift in the sector towards sustainable packaging. Companies are now investing in innovative packaging solutions that focus on sustainability while maintaining functionality and efficiency.
Sustainability in the Packaging Sector
The world produces approximately 141 million tons of plastic for packaging annually, and consumer and regulatory pressure is pushing companies to reduce the environmental impact of their packaging choices. The circular economy is driving innovations in the packaging sector, aiming to improve the overall sustainability of products. This approach represents a complex challenge for packaging producers, who must balance practicality, cost, and environmental impact. The adoption of easily recyclable materials and designs intended for reuse are becoming increasingly common practices.

Let’s explore the new models of sustainable packaging that companies are moving towards.
1. Biodegradable Resins
Innovation in bio-resins has made fully biodegradable materials available, capable of replacing traditional plastics. Although costs remain high, the growing adoption of these technologies promises price reductions as volumes increase. Biopolymers such as starch, cellulose, PLA, PHB, and PHA are gradually replacing conventional plastics, marking an important step towards a more eco-friendly packaging model.
2. Active Packaging
Active packaging offers a solution for preserving food freshness and ensuring product safety, helping to prevent waste. Oxygen absorbers and moisture regulators are integrated to extend the shelf life of food products, while antimicrobial agents can be added to prevent bacterial growth and enhance safety.
3. Recyclable Packaging
Among the alternative solutions explored by companies are recyclable materials like post-consumer resins (PCR), which effectively respond to waste reduction demands by integrating circular economy principles. Startups are also developing mono-material packaging that is easier to recycle than complex multi-layer systems.
4. Edible Packaging
Edible packaging emerges as an innovative solution for waste reduction. Examples include milk protein-based films that provide eco-friendly alternatives to plastic films, closing the packaging cycle and significantly reducing waste.
5. Modified Atmosphere Packaging (MAP)
Modified atmosphere packaging (MAP) is a technique that maintains food freshness by adjusting oxygen and carbon dioxide levels inside the package. This method extends the life of minimally processed products, helping to reduce waste and environmental impact.
6. Multi-Layer Film Use
Multi-layer films with advanced barrier properties are becoming a key solution for extending the shelf life and maintaining the quality of food. Innovations in coatings and resins are improving product preservation, saving billions in food waste and enhancing food safety.
7. Refillables
Refillable packaging models are gaining popularity as a sustainable alternative to single-use plastic. These models encourage consumers to be proactive by reusing containers, reducing waste, and fostering a culture of reuse. Sectors such as beverages, cosmetics, and household cleaning products are adopting this solution for a more eco-friendly impact.
8. Minimalism
Consumers are demanding simpler packaging that uses fewer materials. Minimalist design has grown in popularity, leading brands to simplify their packaging without sacrificing effectiveness. This approach reduces environmental impact and conveys a message of transparency and authenticity, appealing to a more eco-conscious audience.
Conclusion
The future of packaging is increasingly focused on sustainable and eco-friendly models. Companies must adapt to new materials, technologies, and approaches to meet regulations and consumer expectations. Adopting solutions such as biodegradable, edible, and refillable packaging presents an opportunity to improve environmental impact and maintain competitiveness in an ever-evolving market.
