Having a lot of stored Junk, we have the problem of bringing it down a
ladder and sorting it and then putting some back.
Supermarket plastic carrier bags were good for storage and very handy
to carry up and down the ladder, but i think most are now probably
'degradable' and will soon fall apart into a thousand pieces.
Are there any plastic bags (maybe some bin bag types or similar?) that
will not be degradable, that any one knows of ?
