PLA (polylactic acid) biodegradable bags have gained popularity as an eco-friendly alternative to traditional plastic bags. These bags are made from plant-based materials, such as cornstarch, and are designed to biodegrade in the environment, leaving behind minimal harm. However, many people have questions about the longevity of these bags and whether they can withstand storage for extended periods.
When it comes to storing PLA biodegradable bags, the general rule of thumb is to avoid storing them for more than two years. While these bags are designed to biodegrade, they still have a shelf life, and storing them for extended periods can lead to degradation and loss of integrity. The degradation process can be accelerated by exposure to sunlight, moisture, and heat, so it is important to store them in a cool, dry, and dark place.
After two years of storage, the bags may start to show signs of degradation, such as yellowing or cracking, and may no longer be suitable for use. If you find that your bags have degraded or lost their integrity, it is important to dispose of them properly, as they may not be biodegradable anymore.
It is also essential to note that biodegradable bags should not be treated like traditional plastic bags. While they are designed to break down, they require specific conditions to do so. Biodegradable bags should not be mixed with regular plastic bags or put in landfills as they will not break down properly. Instead, they should be composted in a commercial composting facility or disposed of in a green waste bin where they can break down naturally.
In summary, PLA biodegradable bags have a shelf life of two years, and it is important to store them properly to avoid degradation. After this time, they may start to lose their integrity and no longer be suitable for use. Remember to dispose of them properly to ensure they can biodegrade as intended.
