Biodegradable Packaging —How it Works, Definition and Benefits
What Is Biodegradable Packaging?
Biodegradable packaging refers to any type of packaging that naturally disintegrates and decomposes over time, reducing its impact on the environment. However, the term "biodegradable" can be broad and sometimes misleading. While all biodegradable materials eventually break down, the time it takes can vary greatly. For example, a cellulose-based wrapper might decompose in weeks, while a wooden box could take centuries. This wide range in degradation times means that not all biodegradable packaging is equally environmentally friendly.
How to Identify Biodegradable Packaging
To ensure that packaging truly biodegrades in an environmentally safe manner, look for products labeled as "compostable." Certified compostable packaging is designed to break down completely within a specific timeframe under certain conditions, typically within 6 months to a year in home or industrial composting systems. This certification guarantees that the packaging will decompose safely, leaving behind nutrient-rich soil instead of harmful waste.
What Materials Are Used in Biodegradable Packaging?
Contrary to popular belief, biodegradable packaging is not exclusively made from bio-based or plant-based materials. The key to biodegradability lies in the molecular structure of the material, particularly the polymer chains that make it up. These polymers must be able to break down into tiny pieces that can be digested by microorganisms. Therefore, biodegradable packaging can be made from both bio-based and fossil-based polymers.
For example, conventional plastics made from fossil-based polymers like PE, PET, and PP are composed of strong carbon chains that take centuries to degrade. In contrast, biodegradable packaging materials such as paper or cellulose have weaker molecular structures, allowing them to disintegrate more quickly.
Understanding Fossil-Based Polymers
Fossil fuels, formed from the remains of dead plants and animals, are often associated with non-biodegradable plastics. However, some fossil-based plastics, like PBAT, have weaker carbon chains that allow them to biodegrade efficiently while maintaining the durability and flexibility needed for packaging. This makes them ideal for biodegradable food packaging, as they offer the benefits of traditional plastics without the long-lasting environmental impact.
Types of Biodegradable Packaging
There are various types of biodegradable packaging available, though not all are suitable for food products. Here are some examples:
- Hemp: Derived from the cannabis plant, hemp is highly biodegradable and versatile but remains costly and not yet widely available in its polymerized form.
- Paper: A traditional, compostable material that biodegrades quickly and is easily recyclable, though it lacks the protective qualities needed for many food packaging applications.
- PLA (Polylactic Acid): A bio-based material that can be molded like conventional plastic but is slow to compost, even in industrial settings.
- Cellulose: Plant-based and highly biodegradable, ideal for short-term packaging but not suitable for long-term food storage.
- Seaweed: Similar to cellulose, seaweed-based packaging is biodegradable and suitable for short-term use but not stable enough for food packaging.
Biodegradable food packaging requires a material that is durable enough to protect the product during transport and storage but also fully biodegradable within a reasonable timeframe. TIPA compostable packaging, for example, combines bio-based and fossil-based polymers to achieve this balance.
Why Biodegradable Packaging Is Crucial
As waste generation continues to rise globally, biodegradable packaging offers a vital solution to reduce environmental harm. With millions of tons of plastic entering oceans each year, finding sustainable alternatives is more important than ever.
Biodegradable packaging, especially in the food industry, plays a crucial role in creating a circular economy. By composting packaging waste, we can produce nutrient-rich soil that supports farming and food production, reducing the environmental impact of waste and promoting sustainability.
The Importance of Biodegradable Packaging in the Food Industry
The difference between biodegradable and non-biodegradable packaging is stark. While both may be used to package food, biodegradable options like banana peels naturally decompose, whereas plastic bags can persist in the environment for centuries.
In the U.S., 63% of solid waste comes from packaging, and this figure is rising. By transitioning to biodegradable packaging, the food industry can significantly reduce waste and contribute to a circular economy. Instead of sending tons of plastic to landfills, biodegradable packaging can decompose naturally, returning valuable nutrients to the soil.
Benefits of Biodegradable Packaging
The benefits of biodegradable packaging extend far beyond waste reduction. They include:
- Supporting Farming: Biodegradable packaging waste can be composted, enriching the soil and supporting agriculture.
- Healthier Solutions: Biodegradable packaging is nontoxic and natural, making it a safer option for food and food products.
- Waste Reduction: By using biodegradable packaging, we can reduce the amount of waste that ends up in landfills or the ocean.
- Natural Decomposition: Certified compostable packaging is designed to break down within a set timeframe, ensuring it returns to nature without causing harm.
conclusion
biodegradable packaging represents a key strategy in addressing the environmental challenges posed by waste. By choosing biodegradable options, particularly in the food industry, we can contribute to a healthier planet and a more sustainable future.
At Vograce, we don't just give quality products but custom packaging as well. We are thoughtful about your presentation and will give you the best transparent and biodegradable packaging. It's our duty to give a detailed guide on the packaging for easy usage.
We use a water based adhesive that is non-toxic. Vinyl is not, however. Also, all of our materials are OSHA compliant.
