Compostable plastic bags are becoming a popular choice as more people look for better alternatives to traditional plastic. Many households and businesses now ask — are compostable plastic bags safe and reliable for food packaging and storage?
In this blog, we’ll explain how compostable plastic bags work, whether they’re safe for food use, their key benefits, and what to watch out for when using them for storing food.
What Are Compostable Plastic Bags?
Compostable plastic bags are made from plant-based materials like corn starch, PLA (polylactic acid), or PBAT. Unlike regular plastic, these bags break down into natural elements in composting environments, leaving no harmful residue behind.
They are often confused with biodegradable plastic bags, but there’s a key difference: compostable bags decompose faster and more completely under specific composting conditions, making them more eco-friendly.
Are Compostable Bags Safe for Food Contact?
Yes, many compostable food storage bags are certified food-safe. Reputable manufacturers produce food-grade compostable bags that meet safety standards set by regulatory bodies such as the FDA or EU food safety authorities. Look for certifications like:
- EN 13432
- ASTM D6400
- OK Compost (Home or Industrial)
- FDA food contact approved
These certifications ensure that the compostable bags are free from toxic chemicals, heavy metals, or plasticisers, making them safe for storing fresh produce, dry goods, and snacks.
Benefits of Compostable Plastic Bags for Food Packaging
- Non-toxic and chemical-free: Compostable bags don’t leach harmful substances, making them ideal for storing fruits, vegetables, bread, and snacks.
- Breathable material: They allow moisture and air to pass through, which helps keep produce fresh for longer periods.
- Reduces plastic waste: Using eco-friendly food packaging helps reduce landfill waste and supports a circular economy.
- Odourless and safe: These bags don’t carry the plastic smell that traditional packaging often has.
How Can Compostable Bags Be Used for Food Storage?
You can use compostable plastic bags to store a variety of food items such as:
- Fresh fruits and vegetables
- Baked goods
- Dry snacks like nuts or chips
- Sandwiches or meal preps (short term)
They are perfect for storing food for a short period, especially in pantries or at room temperature.
Best Practices for Using Compostable Bags for Food
- Store dry or semi-moist foods in cool, dry conditions.
- Avoid direct sunlight or high-humidity environments.
- Dispose of used bags in home or industrial compost bins, not regular trash.
