I keep a lot of my stuff organized in normal disposable plastic bags I have left after shopping at various markets. And it works fine, except after a couple years I often find a bag in shreds, simply falling apart. Biodegradable - reaching their end of life, making a mess in my stuff and not serving their purposes. I'd be better off disposing of them or not getting them in the first place. Sometimes they are labeled, but sometimes there is nothing to signify whether they can last years or will fall apart.
Is there a reliable way to distinguish these from non-degradable plastic bags before they start falling apart?
