What Is Edible Packaging
Edible Packaging Basics
Edible packaging is crafted from biodegradable, food-grade materials that can either be consumed as part of your meal or naturally break down over time. Its core idea revolves around three main qualities: it’s biodegradable, safe to eat, and made from renewable resources. Essentially, it eliminates waste rather than just managing it.
What makes edible packaging stand out is its dual role. Like traditional packaging, it safeguards food during transport and storage. But it goes a step further by serving as food itself or as compost. This aligns with the principles of a circular economy, where nothing is wasted, and everything has multiple purposes. These features are made possible through the use of natural materials.
Materials Used in Edible Packaging
Edible packaging incorporates a variety of natural ingredients, such as seaweed, rice, potato starch, milk proteins, and gelatin. Each material brings unique properties that make the packaging both functional and edible.
Seaweed has become a standout material in this field. It’s waterproof, flexible, and nutrient-rich. Compounds like alginate, extracted from seaweed, are used to create films that can hold both liquids and solids. Starch-based materials, particularly those derived from potatoes, offer strong barrier properties and dissolve easily in warm water.
Milk proteins also play a significant role in enhancing packaging performance. Studies reveal that films made from milk proteins are up to 500 times more effective at blocking oxygen compared to traditional plastic wrap. This superior barrier helps keep food fresh while relying entirely on natural components.
"The materials mainly used to make edible packaging include polysaccharides, proteins, lipids, and blends of these (composites) with appropriate surfactants, if necessary."
- Melvin Pascall, professor of food science and technology at The Ohio State University
Some edible packaging goes beyond mere functionality by incorporating flavors, nutrients, or other beneficial ingredients. Picture a drinking straw that adds a touch of vanilla to your beverage or a burger wrapper that boosts your meal with extra vitamins. This turns packaging into a value-added part of your dining experience.
How Edible Packaging Helps the Planet
The use of innovative, natural materials in edible packaging offers clear environmental benefits. In 2015 alone, over 141 million metric tons of plastic packaging waste were discarded globally. In the U.S., the average person generates about 140 kilograms of packaging waste annually. By replacing single-use plastics with edible options, this growing waste issue can be directly addressed.
Edible packaging also supports a circular economy by relying on renewable resources instead of fossil fuels. Materials like seaweed and plant-based starches can replace petroleum-based plastics, creating a more sustainable production cycle and potentially reducing carbon emissions.
Additionally, it helps cut down on food waste. By preserving freshness and extending shelf life, edible packaging ensures less food is spoiled before it’s eaten. And since the packaging itself can be consumed, consumers gain added nutritional benefits while businesses save on disposal costs.
The demand for sustainable packaging is growing rapidly. Over 80% of consumers now prefer eco-friendly options. This combination of environmental awareness and practical benefits is driving the adoption of edible packaging.
"We face a huge challenge in developing new packaging materials that protect food all through the supply chain while being recyclable, compostable, produced with renewable energy, or even edible."
- Sara Risch, Ph.D., principal at the consulting firm Science by Design
Globally, takeout orders alone generate around 269,000 U.S. tons of plastic waste annually. The world also uses 500 billion plastic cups each year, and more than half a billion plastic straws are discarded daily. Edible packaging provides a way to significantly reduce this waste while offering nutritional value instead of environmental harm.
