Sustainable Packaging Trends in the Beverage Industry
With the industry evolving, several key trends in sustainable packaging have emerged. Brands are innovating to meet sustainability goals and consumer demands. Here are some notable trends:
- Smart Packaging: Beverage brands use QR Codes in numerous forms to connect consumers to the digital world, providing them with quick links to nutritional information or grabbing their attention with interactive promotional content.
- Paper-based Bottles: Polyethylene furanoate (PEF) is an organic polymer with similar properties to PET. Frugalpac, a British company, created the Frugal Bottle using layers of recycled paperboard fused with water-based
- Plant-Based Packaging: Plant-based materials such as sugarcane-based polyethylene and cellulose are used for packaging. Carlsberg developed a biobased beer bottle, and Coca-Cola partnered with various tech companies to build a bottle prototype made entirely from plant-based sources.
- PET (polyethylene terephthalate) Bottles are replacing Glass Bottles. They are made of 100% recyclable plastic and are used as classic packaging for beverages like beer, wine,
Challenges Faced by The Industry in Implementing Sustainable Packaging Practices
Despite these advancements, the industry faces significant challenges in fully implementing sustainable packaging practices.
- Cost of Sustainable Packaging: Sustainable packaging incurs higher costs than conventional packaging. Procurement of materials, less developed supply chains and manufacturing processes, and limited economies of scale associated with sustainable packaging are some factors attributed to its high cost.
- Food Safety and Regulatory Compliance: The FDA rigorously regulates packaging that directly interacts with food to uphold high standards for labeling, materials, and contact. With regulations constantly evolving and differing across borders, compliance poses a complex challenge as the industry continues to globalize.
- Optimising Material Performance to Protect Goods: Sustainable materials are required to exhibit the same level of performance as non-sustainable alternatives when utilized for packaging. The primary function of packaging is to safeguard the items it contains, leaving no room for compromises in this regard.
Sustainable Materials for Beverage Packaging
To overcome these challenges, the industry is exploring various sustainable materials.
- Cellulose: Cellulose is a complex carbohydrate in plants’ cell walls. Its versatility (cellulose film, paperboard, films) allows for its wide range of applications.
- Bioplastics: PLA and PHA are commonly used bioplastics made from renewable resources.
- Aluminium Cans: Aluminium is highly recyclable, and its lightweight nature reduces transportation-related emissions, resulting in a low carbon footprint.
- Flexible Drink Pouches: Flexible drink pouches present a viable, sustainable alternative to conventional rigid packaging. They are made from lightweight materials like recyclable plastics or compostable films.

- Cellulose or bioplastic options become attractive when minimal environmental impact is prioritized at the end of a product’s life cycle.
- For situations where recyclability is a crucial concern, recycled Aluminium Cans or Cellulose with well-established recycling programs are excellent options.
- If cost is the primary factor, recycled Aluminium Cans or Flexible Pouches are the most suitable solutions.
Regulations On Sustainable Packaging
Regulations on sustainable packaging in the beverage industry promote recyclable materials, recycled content, clear labeling, and the reduction of single-use plastics. They aim to minimize environmental impact, encourage responsible packaging practices, and foster a shift towards more sustainable alternatives.
Vital regulatory bodies and their initiatives:
- Food and Drug Administration (FDA) – United States: The FDA regulates and sets standards for food safety, including beverages, ensuring compliance with labeling requirements, ingredients, and manufacturing practices.
- European Food Safety Authority (EFSA) – European Union: EFSA provides scientific advice and guidance on food and beverage safety to the European Commission and member states, ensuring the safety and integrity of beverages in the EU market.
- Food Standards Agency (FSA) – United Kingdom: The FSA sets regulations and guidelines for food and beverage safety, including labeling requirements, hygiene standards, and allergen management.
- Ministry of Health, Labour and Welfare (MHLW) – Japan: The MHLW regulates the safety and quality of beverages in Japan, overseeing labeling, quality standards, and strict regulations for alcoholic beverages.
