One of the biggest uses we made of plastic was bagging up veggies and fruit that had been partially used and thereafter needed to be refrigerated. We assumed, (erroneously it turns out), that there wouldn’t be a cheap, non-plastic alternative that took proper care of such things – As in, kept them relatively fresh, didn’t let them dry out, rot, mold, etc. We were wrong indeed.
We bought a box of these relatively heavy duty wax paper sheets, which were something like $9 for 500 sheets – Lo and behold, they do a great job with everything we used to trust to plastic – Veggies, fruit, protein leftovers, basically anything that’ll fit the sheet, which naturally leads us to get a roll or two of full sized waxed paper as a backup.
Problem solved, without loss of food quality or safety – A fine win-win.
