What is the shelf life of biodegradable plastic bags, and how does it compare to traditional plastic bags?

The shelf life of biodegradable plastic bags can vary depending on several factors, including the specific materials used, storage conditions, and exposure to environmental factors. Here's a comparison between the shelf life of biodegradable plastic bags and traditional plastic bags:

Biodegradable Plastic Bags:

Biodegradable plastic bags typically have a shelf life similar to that of traditional plastic bags, ranging from several months to a few years under normal storage conditions.
However, biodegradable plastic bags may have a shorter shelf life if exposed to moisture, heat, or sunlight, as these factors can accelerate the biodegradation process.
Proper storage in a cool, dry place away from direct sunlight can help extend the shelf life of biodegradable plastic bags and maintain their integrity until use.
It's important to note that the shelf life of biodegradable plastic bags does not necessarily indicate their biodegradation timeline, as biodegradation may occur only under specific environmental conditions, such as exposure to microbes in composting facilities or soil.
Traditional Plastic Bags:

Traditional plastic bags, such as those made from polyethylene (PE) or polypropylene (PP), are known for their long shelf life and resistance to environmental degradation.
Under normal storage conditions, traditional plastic bags can remain intact for decades or even centuries, with minimal degradation over time.
While the durability of traditional plastic bags makes them suitable for long-term storage and transportation, it also contributes to their environmental impact, as they can persist in landfills and natural environments for extended periods without breaking down.
Unlike biodegradable plastic bags, traditional plastic bags do not undergo biodegradation but rather fragmentation into smaller pieces over time, leading to potential environmental pollution and harm to wildlife.
In summary, while the shelf life of biodegradable plastic bags may be comparable to traditional plastic bags under ideal storage conditions, their biodegradability offers a distinct advantage in terms of environmental impact and end-of-life disposal options.
