Ha not necessarily. We could also eat it if it gets into the soil. Or drink it if it gets into the water. The reason I know is because I once left a roll of shrink wrap (the kind you'd use to wrap up luggage or boxes) down the side of my shed for a summer by accident. After the tail end of a British summer that thing was disintegrating in my hands. Had to be careful to dispose of it without just spreading it.

That wrap was more heavy duty than the kitchen stuff. It had been left in partial sun down the side of my shed and it had only been subject to a few months of British summer. Where even the direct UV index would never really exceed 7. Let alone partial shade.

So it made me realise how quickly plastic wrap can degrade in UV. You can get special stuff that's more UV resistant but it costs a lot of money. Even then you'd be lucky to exceed 7 years I think.

Yeah for sure. I just thought over 26 years the family did a good job of keeping it stored well and never leaving it out.

Does in sunlight. UV tends to break down most plastic and I can't see plastic wrap being particularly UV resistant as it has no need to be. Normally. If you're not keeping it for 20+ years.

Edit: sorry, to be clear I just meant it would degrade by breaking down into tiny pieces. Not trying to say it is biodegradable or anything. Just that it'll go brittle and turn to dust if too much UV gets to it.

I was thinking it's a short life ha. I think it says something about how well stored it was though that it didn't degrade in that time.
