Query: Better to use nothing

These bags are in very good condition and packaging when they arrived, but not sure whether it has been in stock for too long or whether the corn material inside the bags were breaking down or something, I found these bags are not as strong as what I used to buy, the same thing. Hope this won't happen again, otherwise, I do not trust these biodegradable bags anymore. Thanks!
